So I can animate a movie/short film, take a screencast of it, and use Phosphor to render the movie on the client side?

That plus html5 audio could be a new low bandwidth way to stream movies in the future

if you are animating the movie, just export from your app as prores. that's how some of our gallery clips are done (the logo spin for instance in blender 3d model rendered straight to quicktime)

Isn't it interesting how, caused by our inability to directly embed video onto websites, we are basically forced to reinvent video codecs in Javascript?

This basically means that on most mobile devices, instead of a hardware-accelerated decompressor, a slower, more CPU-consuming Javascript VM is in charge of video.

While technically impressive, I would much prefer the possibility of directly embedding (and controlling) real video.

On iPad 1 all samples from the Gallery run at, what feels like, 1-2 fps. The screeencast in the blog though is very smooth. Why's the difference?

Same on the iPhone 4S. I have a feeling it's because they're all running at once.

So Apple dug a hole by:

- not allowing iOS to play videos in-DOM.

- deciding not to support WebM, so Firefox users can't see their videos.

And now others are following them by helping to dig deeper in a vastly inefficient way of displaying moving images ? What could previously be offloaded to dedicated engines is now going to burn the CPU via JS. Hum, now that's gonna work…

This looks great - And fits perfectly into a need I had at the moment for sharing smaller screencasts.

I had a few crashes with it this morning on a rMBP, what's the best route for support ? (your forums do not seem updated yet for phosphor)

The video was so smooth I didn't realise what the example was. I actually watched the example video through several times thinking "what? there's no video on that page!" before realising that the thing I was watching was the video.

    HTML 5 video: iOS devices won't play video tags in the
    DOM, they instead open in a standardized player. Apple
    also stops them from auto-playing on iPhone.

This is what makes Vine so useless on iOS outside of the native app. It makes it preferable to use GIF sans audio generally, whenever it's an option.

I get where Apple is coming from, but this is definitely sorely needed for some use cases.

html5 video and a good codec are a way better use of bandwidth. This technique is good for animations with few moving parts. For example the Alfa animation http://www.divergentmedia.com/phosphor/gallery#alfa needs to download 14 additional images for a total of 3.5 megabytes for a few seconds' worth of animation.
