jonathan@openshot.org (Jonathan) — Mon, 16 Mar 2026 20:52:44 +0000

Buckle up, everyone. OpenShot 3.5 has arrived, and it is one of the biggest releases in our 18-year history. From a much faster timeline to better exports, improved GPU acceleration, smarter effects, and stronger stability, this release moves OpenShot forward in a big way. I am incredibly proud of it, and I cannot wait for everyone to try it.

Download OpenShot now and take it for a spin.

TL;DR

New default timeline with much faster zooming, scrolling, editing, and new keyframe panel
35% faster overall, with especially large gains in effects and frame processing
Better exports with smaller files and higher quality
Improved GPU acceleration for decoding and encoding
Improved stability with expanded tests, UI tests, and full-cycle replay testing
Audio transitions make cross-fading audio super simple

Tons of bug fixes across editing, playback, caching, and platform-specific issues

OpenShot 3.5 is all about making editing feel smoother and more dependable. Whether you are cutting together a quick video, building a more complex project, or experimenting with AI-assisted workflows, this release lays a much stronger foundation for what comes next.

A new default timeline, built for speed

OpenShot 3.5 now uses the newer timeline as the default editing experience, and it is one of the most noticeable improvements in the release. Zooming, scrolling, dragging, trimming, and scrubbing feel much smoother, especially on larger projects. The new timeline is simply more responsive and more enjoyable to work with day to day. Alongside it, the keyframe panel is now enabled by default, making advanced animation and property editing much easier to discover and use.

Technical notes: Better timeline rendering, smoother drag and snap behavior, improved multi-selection handling, high-DPI thumbnail support, more stable preview updates, and a more polished default keyframe workflow.

Big performance gains across the editor

Performance was a major focus throughout the 3.5 release cycle. Overall benchmark results show OpenShot 3.5 is about 35% faster, with some of the biggest improvements landing in effects and frame processing. That means better responsiveness during editing, faster previews, and a smoother feeling editor overall. The biggest wins show up in areas like Chroma Key, color effects, and clip processing, but the gains are broad and spread throughout the engine.

Technical notes: Faster hot paths in libopenshot, improved frame processing, optimized effect loops, better cache behavior, and broad engine-side performance work across readers, frame mapping, masks, the timeline, and writing.

Better exports and improved GPU acceleration

OpenShot 3.5 improves export quality in practical ways that users will notice right away: smaller files, better visual quality, and improved defaults for common export presets. At the same time, GPU-related handling has been improved for both decoding and encoding. This makes hardware acceleration more reliable, helps avoid black-frame issues when decoding fails, and gives OpenShot a better path for falling back safely when needed.

Technical notes: Updated export presets and encoder tuning, improved CRF-based defaults, better GOP/B-frame handling, safer hardware decode fallback, and improved hardware verification behavior.

Audio transitions and much better audio file handling

Audio got some very meaningful quality-of-life upgrades in 3.5. Transitions are now much smarter about sound, making it easier to create cross-fades, fade-ins, and fade-outs without extra manual work. On top of that, audio file handling is faster and more responsive in the UI, making import and day-to-day editing feel snappier. These improvements make audio work feel more natural and less fiddly.

Technical notes: Timeline-aware audio fades tied to transitions, equal-power cross-fade behavior, faster audio decoding paths, improved waveform generation, and faster handling of audio-heavy project workflows.

Masks, Chroma Key, and more powerful effects

Effects got stronger in OpenShot 3.5, both in quality and in flexibility. A new default Chroma Key mode delivers softer edges, better halo handling, and major performance gains. Mask support has also expanded across more effects, animated masks behave better, and new controls make it easier to build more advanced effect workflows. Together, these changes make OpenShot more capable for compositing, selective effects, and fine-tuned edits.

Technical notes: New default soft chroma mode, improved animated mask timing and trimming, mask inversion and expanded effect mask support, better effect behavior defaults, and significant effect-side performance gains.

Stability, testing, and a long list of bug fixes

One of the most important parts of OpenShot 3.5 is what it fixes. This release includes tons of bug fixes across playback, timeline editing, dragging, trimming, caching, missing-file handling, and platform-specific issues. It is also backed by stronger testing: expanded unit test coverage, new UI unit tests, and the new openshot-replay testing suite for broader full-cycle testing. The result is a release that feels more dependable and less fragile in everyday use.

Technical notes: Expanded automated testing, more regression coverage, UI-level testing, replay-based full-cycle testing, and fixes across caching, preview correctness, playback edge cases, and platform-specific paths.

Experimental: ComfyUI integration for AI workflows

OpenShot 3.5 also includes early experimental ComfyUI integration, opening the door to more advanced AI-assisted workflows. This includes support for a growing list of workflows, plus custom OpenShot-oriented work around tracking, segmentation, and SAM2-powered pipelines. It is exciting work, but it still requires setup and is best thought of as an advanced feature for adventurous users. We are laying the groundwork now so this can grow into something much more powerful over time. See our ComfyUI installation guide to learn more.

Technical notes: Dynamic workflow loading, JSON-driven ComfyUI integrations, support for generation and advanced tracking/segmentation flows, and OpenShot-specific workflow work that is still evolving.

How Do I Split a Clip?

jonathan@openshot.org (Jonathan) — Tue, 20 Jan 2026 20:32:29 +0000

Splitting a clip lets you cut a video or audio clip into separate pieces so you can remove mistakes, tighten pacing, or add transitions.

Splitting a clip is used when you want to change or remove part of a video without affecting the rest of it. Instead of trimming the beginning or end, splitting allows you to work with individual sections of the same clip on the timeline.

What does “split a clip” mean in video editing?

When you split a clip, you create a cut at the playhead (the current timeline position). After the split, the original clip becomes two clips—each piece can be moved, trimmed, deleted, or edited on its own.

How to split a clip in OpenShot

Add your clip to the timeline. Import your video (or audio), then drag it onto a track.
Move the playhead to the cut point. Place it exactly where you want the split.
Select the clip. Click the clip so it’s highlighted.
Slice the clip. Right-click the clip and choose Slice, or use the slice tool.
Choose the slice option. Select slicing at the playhead.
Edit the new pieces. Move, trim, delete, or add a transition.

Tip: Zoom in on the timeline before slicing for more precise cuts.

Try it in OpenShot

If you’re new to editing, splitting clips is one of the fastest ways to improve pacing and remove mistakes. Download and install OpenShot Video Editor (free and open-source), then practice slicing a clip a few times—you’ll use this workflow in almost every project.

How Do I Trim the Start or End of a Video?

jonathan@openshot.org (Jonathan) — Tue, 20 Jan 2026 18:56:58 +0000

Trim the start or end of a video to remove unwanted footage. This step-by-step tutorial shows how to trim video clips in OpenShot.

Trimming a video is one of the quickest ways to clean up footage before you start making more detailed edits. It’s especially useful for removing awkward starts, long pauses, or extra seconds at the end of a clip so your video feels more polished.

What does it mean to trim a video?

When you trim a clip, you shorten it by adjusting its start point, end point, or both. Trimming removes unwanted frames from the edges of a clip without creating multiple pieces.

This makes trimming ideal for simple edits like removing dead space, false starts, or extra footage after the action is finished.

How to trim the start or end of a video in OpenShot

Add your clip to the timeline. Import your video and drag it onto a track in the timeline.
Select the clip. Click the clip so it’s highlighted.
Hover over the clip edge. Move your mouse to the beginning or end of the clip until the cursor changes to a resize icon.
Click and drag to trim. Drag inward from the start to remove the beginning, or drag inward from the end to remove the ending.
Preview your trim. Play the clip to check the timing. You can adjust the trim again at any time.

Tip: Zoom in on the timeline before trimming for more precise, frame-accurate edits.

When should I trim vs split?

Trim when you only need to remove footage from the beginning or end of a clip.
Split when you need to remove or rearrange something in the middle of a clip.

In most editing workflows, you’ll trim clips first and then split them later as your edit becomes more detailed. Both tools work together.

Try it in OpenShot

Trimming is fast and visual in OpenShot Video Editor, making it easy to clean up footage without complex menus or settings. Download and install OpenShot (it’s free and open-source), then practice trimming a few clips—you’ll use this skill in almost every video you create.

How Do I Remove a Section from the Middle of a Video?

jonathan@openshot.org (Jonathan) — Mon, 19 Jan 2026 23:14:41 +0000

To remove part of a video from the middle, you split the clip at the start and end of the section you don’t want, then delete the unwanted piece.

Removing a section from the middle of a video is useful when you want to clean up footage without changing the beginning or end of a clip. This technique is commonly used to cut out mistakes, long pauses, or unwanted moments while keeping the rest of the video intact.

The easiest way to do this is by splitting the clip at two points—once at the start of the section you want to remove, and once at the end—then deleting the middle piece.

How to remove the middle of a video in OpenShot

Add your clip to the timeline. Import your video and drag it onto a track.
Move the playhead to the start of the section. Place it where the unwanted part begins.
Split the clip. Right-click the clip and choose Slice, or use the slice tool.
Move the playhead to the end of the section. Place it where the unwanted part ends.
Split the clip again. This creates three separate pieces.
Delete the middle piece. Click the unwanted section and press Delete.

Tip: Zoom in on the timeline before splitting to make sure your cuts are precise.

Try it in OpenShot

Cutting out unwanted sections is one of the fastest ways to improve a video. OpenShot makes it easy to split and delete parts of a clip visually on the timeline, so you can clean up your footage in seconds.

How Do I Rotate a Video?

jonathan@openshot.org (Jonathan) — Sun, 18 Jan 2026 23:18:34 +0000

Rotating a video lets you fix sideways or upside-down footage by adjusting the clip’s rotation so it displays correctly.

Rotating a video is most commonly needed when footage is recorded in the wrong orientation, especially on phones or handheld cameras. This lets you correct the angle of a clip without re-recording or changing the rest of your edit.

OpenShot lets you rotate a video visually using simple controls, making it easy to fix orientation issues in just a few steps.

How to rotate a video in OpenShot

Add your clip to the timeline. Import your video and drag it onto a track.
Select the clip. Click the clip so it’s highlighted.
Open the clip properties. Right-click the clip and choose Properties.
Adjust the rotation value. Change the rotation setting (for example, 90°, 180°, or 270°) until the video is oriented correctly.
Preview the result. Play the video to confirm the rotation looks right.

Tip: If black bars appear after rotating, you may need to resize or scale the clip to fill the frame.

Try it in OpenShot

Fixing video orientation is quick and beginner-friendly in OpenShot. Rotate your clips to the correct angle, then continue editing without worrying about sideways or upside-down footage.

Cosmic Dusk Theme (preview)

One of the most exciting changes in OpenShot 3.2 is our new Cosmic Dusk theme (shown below). This theme is currently included as a "preview" to collect feedback and share our progress. We have invested a huge amount of time into this UI design and work-flow, but still have much work remaining. You can switch to this theme in the Preferences to give it a try! You will notice new toolbars, new icons, a more compressed and efficient timeline design, relocated undo/redo buttons closer to the timeline, and a host of new things to discover.

Remove That Gap!

Now you can right click on any gap between clips, and select Remove Gap. This is a huge time saver, as you can do this with a single click. All clips to the right will shift over by the amount of the gap. You can also right click on the Track, and select Remove All Gaps. Previous versions of OpenShot required users to manually select all clips to the right, and drag/snap them to the left, which is slow, and prone to inaccuracies.

How to Install OpenShot

Download OpenShot 3.1 and follow our step-by-step installation guide.

400+ Video Profiles

OpenShot now includes more than 400 video profiles, which are fully searchable. The research into this feature was very interesting, and included building a large metadata database of known video resolutions, frame rates, aspect ratios, devices, and pixel ratios - and a new management script which can validate, dedupe, and generate/update our existing profiles. Moving forward it will be extremely easy to add new resolutions, new frame rates, and new ratios. For more information on video profiles, check out our User Guide.

Time Remapping Improvements

While OpenShot has included some basic time remapping features for a while, they were quite limited, and would often crash when speeding up or slowing down videos. These crashes have been eliminated, and a much more robust time remapping implementation has been added. This includes vastly superior audio resampling support for backward and forward videos. It also now supports time keyframes using Bezier curves to incrementally speed up / slow down video and audio.

Undo / Redo Transactions

One of the most requested features in OpenShot is for better Undo / Redo support, especially for multi-step edits, such as slicing a clip into 2 clips or removing a track (i.e. which moves many clips at the same time). All multi-step edits now support a transaction system behind the scenes, which groups these multi-step edits together. All operations in OpenShot now take a single click to undo.

Captions & Audio-Only Waveforms

The Caption effect has gotten some much needed love, and has improved support for VTT/Subrip syntax, including a new set of default keyframe properties, which correctly scale to different resolutions, including High DPI screens. Also, OpenShot now supports waveform visualizations for audio-only files (prior to effects being rendered), which now allows effects, such as the Caption effect, to be added to audio-only files. This is a very effective way to make audio-only edits much more interesting (waveforms + colors + caption text).

Memory Leaks & Bug Fixes

We have identified and fixed ALL known memory leaks in OpenShot's source code, including killing zombie threads, making OpenShot much better at maintaining and reclaiming memory usage. For example, after a video render, your memory will now be reclaimed and threads properly destroyed. This allows for OpenShot to run for very long periods of time without any restarts, and is especially nice for batch renders, long renders, Cloud API renders, and other scripting usages which has OpenShot rendering videos for days without stopping.

Improved Performance

Many of the changes to OpenShot 3.1 improve CPU performance, especially around Frame Mapping (which happens anytime your source video FPS does not match your video profile), and Clip performance (when effects or expensive processing is needed, such as time remapping). Additional cache is used with Clips to prevent duplicate rendering efforts, and Frame mappers are much more optimized, to also prevent duplicate processing of the same frame.

A HUGE Thanks

I would like to thank all of the volunteers, translators, software developers, testers, users, donors, and everyone who contributed to OpenShot 3.1! I would also like to give a special thanks to Shawn (and Denise), and Raffi for their efforts and personal sacrifices to make OpenShot the best free video editor in the world!

How to Install OpenShot

Download OpenShot 3.0 and follow our step-by-step installation guide.

Improved Stability

We have worked tirelessly over the past 12 months to identify and fix as many stability issues as possible in OpenShot. This was a unique challenge, both in finding clever ways to identify and reproduce crashes, and finding solutions that don't impact the performance of OpenShot. A few notable improvements are related to thread safety (during timeline changes and video playback caching), multi-threaded unit tests designed to flush out race conditions and concurrency issues, safer object clean-up and deletion, and updates to the Undo/Redo system to prevent crashes (for example, when spamming undo).

Enhanced Real-Time Video Playback Performance

One of the largest and most noticeable changes to OpenShot 3.0 is our improved video preview, resulting in smoother video preview and fewer freezes and pauses during previewing. But to understand why things are so much smoother, we need to look deeper into our decoding engine. We have rearchitected our decoder to be much more resilient to missing packets, missing timestamps, and better understanding when we are missing video or audio data, so we can move on without pausing.

Dozens of bug fixes and related improvements have also helped OpenShot 3.0 expand compatibility to more video formats and codecs, especially newer ones, which tend to be more reliant on multi-threaded decoding, such as AV1. Also, many improvements related to EOF (end of file) detection and file duration detection have further expanded the compatibility, even for badly encoded files with missing timestamps, and incorrect durations (which is very common in JavaScript encoded videos, and certain types of video capture files).

Video caching has also been heavily refactored and improved, to offer new functionality and more optimizations. OpenShot utilizes a caching background thread, which prepares upcoming frames before they are needed. This caching algorithm has been improved to operate at different speeds (1X, 2X, 4X) and in both forward and backwards directions. It also now includes a pre-roll to build up video frames before playback starts, offering a smoother playback experience. Many new caching related settings can be set in the OpenShot Preferences, and the user can now clear the cache any time, by right clicking on the playhead and clicking "Cache->Clear All".

Timeline Improvements

The timeline has seen lots of love as well in OpenShot 3.0, and includes some great quality of life improvements, making OpenShot even easier to use. Snapping accuracy has been dramatically improved (while trimming and moving clips / transitions). Holding SHIFT will cause the playhead line to snap to the edges of clips. Slicing clips with our razor tool is now faster (requiring less CPU). Keyframe icons have gotten a much needed face lift, and are also more accurate (i.e. position). Keyframe icons now represent the interpolation mode (circle for bézier, diamond for linear, square for constant), and are clickable and filterable. Video effects now have unique colors for each effect. Transitions now set their own direction (i.e. fade-in vs fade-out), depending on where they are dropped.

For those users who enjoy working with audio waveforms, this feature has also been heavily expanded and optimized in OpenShot 3.0. We now cache waveform data per file, and store this inside the OpenShot project file. This allows for persistent waveform caching across editing sessions, and fast waveform rendering when slicing and adding the same file to the timeline multiple times. We also have a more accurate waveform algorithm utilizing RMS (root mean square), and our timeline zoom slider allows the user to zoom down to frame accuracy on a clip, for perfect alignment with waveforms.

Reduced Memory Footprint

Among the many improvements in stability, we also worked very hard on reducing the memory footprint of OpenShot 3.0, and fixed many memory leaks and threading issues in the process. One of the primary goals of this work was to support extremely long renders (multiple hours), for processing really long recorded streams, security camera footage, and other long format recordings. In our tests, we achieved sustained encoding for more than 12 hours with essentially the same memory utilization the entire time... which is a huge improvement from previous versions of OpenShot.

Animated GIF & MP3

OpenShot 3.0 comes with many new export presets, including Animated Gif, MP3 (audio only), YouTube 2K, YouTube 4K, MKV, and more. We also have better support for anamorphic video profiles (i.e. videos with rectangular pixels)... perfect for working with old home videos.

Export Clips Feature

An exciting new feature in OpenShot 3.0 is the ability to split files into many clips, and then export all these clips at the same time, and in their original profile and format. For example, you can now quickly cut out highlights from your family home video files, select them all, and right click "Export Clips", select a folder, and click "Export". This will generate a unique video file for each clip, and makes it easy to upload to a file sharing site for your entire family.

Blender 3.3 Support

Keeping up with Blender's rapid development is always a challenge (they are super fast). We have updated our animated title templates to work with the latest version of Blender, including fixing various scripting errors which have changed since the last release of OpenShot. Also, we now set Blender to use the current project frame rate (FPS), so your new animated title perfectly matches it, and in high frame rate projects, this can have a huge impact by creating much smoother animations.

Improved Location Preferences

OpenShot 3.0 includes a new preference that affects the default folders used for operations (importing files, saving / opening projects, and exporting). You can choose to either use the current project's folder, or the most recent folder chosen (for that specific operation). In practice, this saves the user time by defaulting to better and more sane default folders, but with this new preference, the user can quickly customize the behavior for their unique workflow.

Sorting + Translation Improvements

While OpenShot has always sorted things in alphabetical order, such as effects, transitions, emojis, animated titles, and titles, this was only for English, and when using OpenShot with a non-English language, all our lists were still in English order, and "chaos" is the best word to describe the user interface in that state. So, we have refactored and improved our sorting at runtime, to be language independent. We have also fixed many other issues with our translation system, and we are happy to now report that using OpenShot in non-English languages is vastly improved and feels native! Also, the user can now manually change the sort columns on many views, and toggle the sort direction when needed.

New High DPI Support

OpenShot 3.0 now fully supports high DPI displays and monitors, such as 4K monitors. Many of the assets used in OpenShot, such as icons, cursors, and logos have been swapped out for vector or higher resolution images. Also, the maths used in determining many custom widget sizes, such as our video preview widget, have been updated to be aware of high DPI and scale up the pixels when needed. The end result is a beautiful, HD user interface that is crisp and fully supported on newer, high pixel count displays.

Improved User-Guide / Documentation

A very common complaint from OpenShot users (and prospective users) has always been our user guide. Old and outdated, with screenshots that no longer seem to match our descriptions, and many topics missing. Well, we decided it was time to invest heavily in our user-guide, and we are very proud of the outcome! We now have coverage of all OpenShot features, screens, effects, profiles, presets, titles, and more! We have updated all the screenshots (utilizing higher DPI images). We have over 110 pages of topics, descriptions, and information about how to use OpenShot, and a detailed glossary of video editing terminology. We also added PDF output to our documentation pipeline, and now any changes to our RST documentation files, automatically update our user-guide (and PDF) on openshot.org. It has never been a better time to learn OpenShot!

A Huge Thanks

I would like to sincerely thank all of the volunteers, translators, software developers, testers, users, donors, and everyone who contributed to OpenShot 3.0! I would also like to give a special thanks to Shawn (and Denise), Jackson, Raffi, Brenno, Frank, and Justin for the extra effort, and really helping to make this release possible. Lastly, I would like to thank all of the shoulders we are standing on: FFmpeg, Blender, Inkscape, ReSVG, Python, Django, JavaScript, Qt, and the many other great libraries and projects we depend on.

New AI Effects

For the first time ever, OpenShot now includes computer-vision / AI video effects.

Stabilization provides a simple way to calculate camera shake/motion, and completely eliminate it. This might be one of the most requested features ever, and I’m very proud that it’s now included!

Tracker allows you to draw a box around any element in the video, and we continue to track the coordinates of that object throughout each frame. Once calculated, we store/cache the motion and coordinates for super fast real-time video previews. This motion data can then be used in our animation system, attaching another clip to those coordinates.

Object Detection identifies all objects in a scene, and allows you to draw boxes around certain types of objects (i.e. identify all the people in this scene, or identify all the cars in a scene), or add text labels above each object. You can also use this data in our animation system, attaching a clip to all objects of a certain type. This effect is still in beta (and requires downloading a few extra files, for the AI model), but I went ahead and included it for your enjoyment.

New Audio Effects

A total of 9 audio effects have been added to OpenShot, many of which are based on implementations from the JUCE audio library that libopenshot-audio is based on. Each of these are pretty standard audio effects, and each include many parameters and options. All of these effects are real-time, and are plenty fun to play around with!

Compressor (reduce the volume of loud sounds or amplify quiet sounds)
Expander (louder parts of audio becomes relatively louder and quieter parts becomes quieter)
Distortion (alter the audio by clipping the signal)
Delay (adjust the synchronism between the audio and video track)
Echo (reflection of sound with a delay after the direct sound)
Noise (random signal having equal intensity at different frequencies)
Parametric EQ (filter that allows you to adjust the volume level of a frequency in the audio track)
Robotization (transform the voice present in an audio track into a robotic voice effect)
Whisperization (transform the voice present in an audio track into a whispering voice effect)

New Zoom Slider Tool

One of the historically weakest areas in OpenShot has been the control of timeline scale and general timeline usability, scrolling, panning, and zooming. We have introduced a new feature I’m tentatively calling the “Zoom Slider”. It previews the entire timeline, drawing a tiny representation of every single clip, transition, and track, including which ones are selected. In addition, it allows the user to adjust which part of the timeline they are interested in viewing. Clicking and dragging the blue circles determines which portion of the timeline is visible. Dragging the entire blue area scrolls the timeline horizontally. This feature was requested by my daughter, and I think it turned out amazing!

Improved Performance

With every release of OpenShot we strive to provide stability and performance improvements. This release is no different, and I am happy to report some very big improvements on performance, especially related to threading and CPU usage. Some threads were removed, after testing a single threaded version which was much higher performing. Our performance is very similar to raw FFmpeg in many cases, which is amazing considering how many additional capabilities that OpenShot adds. Another big change is our color format (used internally) has changed from RGBA8888 to RGBA8888_Premultiplied, where our alpha channel is premultiplied into our color data. This makes certain types of compositing/painting much faster and requires less CPU per pixel.

Improved Transform Tool

Selecting any clip now automatically enables “Transform” mode (which can be disabled in the Preferences if needed). Transform mode has been completely overhauled, and contains a ton of polish! Resizing, rotating, scaling, positioning, and shearing have never been easier! It’s also fully compatible with our animation keyframe system, and can quickly create complex animations. Even the mouse cursors are transformed in real-time… which is super cool and very intuitive, since they communicate exactly what is about to happen.

We also have introduced an origin point (the cross hair in the middle), which can be used to control how the shearing and rotation work. And just for fun, the origin point can even be animated as well… which creates some very interesting animation capabilities.

When using your mouse scroll wheel over the video preview, it now zooms in and out of the preview window… allowing you to see objects offscreen. This makes complex animations so much easier, and is a huge improvement!

Improved Snapping

Another feature that has been frequently requested is improved snapping. OpenShot now has the ability to snap while trimming the edges of clips, making it much easier to align the edges of clips on different tracks. The following use cases now work:

Snapping while trimming
Snapping clips to the playhead (trimming or positioning)
Snapping the playhead to clips (if CTRL is pressed)
Snapping accuracy is also improved

Improved Video Effects

Many of OpenShot’s video effects have been extended and improved, along with a few new features. We have added a new Caption effect, which can rasterize/render text onto your video in a very common format (VTT/SubRip). Once you copy/paste the subtitles into OpenShot, you can quickly adjust the font, colors, borders, background, margins, positioning, size, and even add a simple fade in/out animation. With a few clicks, you can add text to your entire video, which will be baked into your final video export. You can also manually insert text at any playhead position, which makes inserting text very simple, even if you aren’t starting with a captions file.

The Saturation effect has been improved to support a color-separated model, with more keyframable parameters, giving the user more control and more accuracy.

Keyframes are now parentable, and can be used to manage more complex animations and more complex timelines. For example, you can parent a bunch of clips to a single parent, and control them all in one place. This is also used on our new Tracker and Object Detection effects.

Lastly, we have new effect icons, which we hope better demonstrate and communicate how an effect will behave.

Emojis (OpenMoji)

We have added nearly 1000 emojis from the great OpenMoji project. These are integrated into OpenShot, and are super useful when learning and experimenting with a video editor for the first time. They can be used for simple animations, overlays, and to add color and interest to various video editing projects.

Quality of Life Improvements & Fixes

The following improvements have also been implemented, which we hope will improve your general experience and enjoyment of OpenShot.

Ability to Import *.osp Projects as Clips
WebEngine & WebKit Support
FFmpeg 4 Support
Faster timeline ruler rendering / more precision / super zoom!
Rotation improvements and EXIF metadata support
Updated Blender support
Faster file importing
FIXED: Incorrect PTS (blank first frame)
FIXED: More audio pops & crackles

REST Cloud API

We have released many new updates for our REST API, which is available on both AWS and Azure marketplaces. The OpenShot Cloud API allows you to create custom videos via simple HTTP Requests (GET, PUT, PATCH, POST, DELETE). With a short script (or any programming language) you can load *.osp/*.zip templates, upload files, create clips, update clips, change keyframes and animations, and export new custom videos. We have a webhook which can POST the JSON details and notify your website of the newly rendered videos once they are completed.
