GNOME Developer Comes Up With New Animated Image Format

[Apopas]

He needs to come up with a better name. Something easy to pronounce.

I'd really like to know how much we'll gain if we take some GIF and convert them to WebM. What's the compression ratio between these two? We might be surprised..

Imgur just recently started converting GIFs to Webm. They're calling it "GIFV"

they using the h264 codec. Here is a demo image (or video without audio), which already works on Firefox, Chromium and some other browsers: http://imgur.com/zvATqgs

Yes, sorry, brainfart. I think someone mentioned WebM in a comment on Imgur and then Creak's comment triggered that memory and I repeated it. It's MPEG-4 AVC a.k.a "h.264" in an MP4 container.

Animated images? That's called videos and we already have good format for them - mp4 (or google's shitty webm).

What if you want lossless compression and transparency? Neither of these are made for that. Also, WebM isn't shitty, it's the best finalized free format currently available.

I can't see why would anyone use mp4 or webm instead of mkv except if it is for the web.

I remember reading that H.264 actually supports lossless compression but nobody actually uses it. (I may be wrong)

Mkv is free.

Webm is based on a limited subset of MKV.

True but mkv is merely a container. One needs a patent uncumbered video and audio codec to play videos without any liabilities. So thats essentially what Google did. VP8 video codec + vorbis audio codec in a container that is based on mkv.

Storing each frame or even just each deltas is just a silly compression technique for videos, lossless or not.
