Leap second FPS

2015-06-13T22:12:00.000-07:00

Isn't this an important question?
what is the frame rate we use or do we just treat it like any other second?

A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time, or UT1.

Leap Second - What is it? - Time and Date

Time and money for. The fact Date › Time Zones

Mobile-friendly - A leap second will be added on June 30, 2015 23:59:60 UTC. A leap second is a second which is added to Coordinated Universal Time (UTC) in order to synchronize atomic clocks with astronomical time to within 0.9 seconds.

Atomic clocks are slightly too accurate.

A leap second is a second which is added to Coordinated Universal Time (UTC) in order to synchronize atomic clocks with astronomical time to within 0.9 seconds.

Why Do We Need Leap Seconds?

The reason we have to add a second every now and then, is that Earth's rotation around its own axis, is gradually slowing down, although very slowly.

Atomic clocks however, are programmed to tick away at pretty much the same speed over millions of years. Compared to the Earth's rotation – which determines the length of a day – the atomic clocks are simply too accurate.

Exactly how do Leap seconds work?

How Often Are Leap Seconds Added?

Did you notice? The last leap second was added at 23:59:60 UTC on June 30, 2012.

Since 1972, a total of 25 seconds have been added. This means that the Earth has slowed down 25 seconds compared to atomic time since then.

This does not mean that days are 25 seconds longer nowadays. Only the days on which the leap seconds are inserted have 86,401 instead of the usual 86,400 seconds.

Can we live without leap seconds?

36 Seconds' Difference

The difference between UTC and the International Atomic Time (UTC-TAI) after the next leap second has been added on June 30, 2015, will be 36 sec.

are they ever going to match up?

Who decides when to add leap seconds?

The International Earth Rotation and Reference System Service (IERS) in Paris, France observes the Earth's rotation and compares it to atomic time. When the difference between the two approaches 0.9 seconds, they order a leap second to be added worldwide.

Just saw this. Having taught for years and worked in the industry, I like to pass on reels I like. This one is basically hard surface modeling and effects, but the breakdown is an inspiration for you students putting together portfolio packages. Bravo Perry!

broadcast studio of the future

2011-09-21T19:04:00.000-07:00

Having an interest in virtual sets since working on the first CBS Election coverage using a virtual set in 1996, I am fascinated by what this company is doing. Found them on Linked In, when they posted on a CG group looking for modelers.

The fountain of the future

I was just looking at FusionCI's demo reel and saw this awesome fountain they did for F10 Studios, who do just amazing architectural visualization Took a while for their reel to download (could be me), but worth it.

Entertainment Tech Show Highlights "Creatasphere"

2011-09-20T18:33:00.000-07:00

My expectations are always limited for this show, as far as CG, as it covers mostly cameras and other live-action tech, and editorial. However, I always learn something, like that Cinema4D is pretty cool now. I am told they have a great education discount.

Saw a presentation on Adobe Premier Pro. I don't see big advantages over FCP, but I'm just a hack.

Also saw the Autodesk guys, although their presence was about Smoke on the Mac. This was pretty impressive actually, running on a Macbook Pro, what I have -- not sure what board.

But the most fun I had was chatting with the Litepanels guy -- the future of set lighting using the new LED technology. Their approach is to imitate the tools and workflow of traditional lighting as close as possible. The arrays can be dimmed, and with some you can swap the color temperature (daylight to tungsten). And since they use 1/10 the power of traditional lights, a number of them are battery operated. They have these little hand-held ones like 3x8 or so, and of course they don't get hot. Close to 2 hours of battery time. 1 1/2 hrs. charge time. I can now at least explain how the new LED lightbulbs will work in casual cocktail party chatter.

Sorry, I meant to include some info. I have always been a big proponent of video art and unusual and experimental short films, as well as any type of computer-generated art of course. Some of my personal heroes include the below.

Some of them I have been fortunate enough to work with.

Isaac is the son of very good friends of mine. I believe that he represents a new generation of video/computer artists. He is only in high school, but I think his work is exceptional.

anyway, just interested in your opinions.

much more to come
