Next-Next Generation Video: Introducing Daala 86
An anonymous reader sends this excerpt from a post by Xiph.org's Monty Montgomery:
"Xiph.Org has been working on Daala, a new video codec for some time now, though Opus work had overshadowed it until just recently. With Opus finalized and much of the mop-up work well in hand, Daala development has taken center stage. I've started work on 'demo' pages for Daala, just like I've done demos of other Xiph development projects. Daala aims to be rather different from other video codecs (and it's the first from-scratch design attempt in a while), so the first few demo pages are going to be mostly concerned with what's new and different in Daala. I've finished the first 'demo' page (about Daala's lapped transforms), so if you're interested in video coding technology, go have a look!"

Wikipedia claims that VP9 does/will support alpha channel

Yes, as far as I can tell thats a pretty solid 'will', closer to a 'may', but alpha there as far as I can tell is just another
channel with no special consideration, unfortunately.
But of course, the more the merrier, its just a very under supported requirement, and one that is heavily used in content creation circles.
Most end up having to use png or target image sequences, or quicktime/animation codec for support, which are somewhat poor workflows.

Daala? That will play well in test/focus groups - I'm certain of it.
Hmm, yeah, because the input of "focus" groups are well known for their role in chosing video codecs. So, let's look at the real commercial codecs out there:
ISO/IEC 11172 aka MPEG-1 ;-)
Dirac Pro aka SMPTE 2042-1-2009 VC-2
H.222 aka H.262 aka MPEG-2 Part 2 aka ISO/IEC 13818-2
MPEG-4 er, which was that, Part 2 aka H.263 aka ISO/IEC 14496-2 or Part 10 AVC aka h.264 aka ISO/IEC 14496-10
MS MPEG-4v3 aka (unofficially) Divx
etc.
So yeah, Daala is terrible by those standards
So, basically you're randomly grousing about OSS is nonsensical and in complete contrast to reality and apparently this has caused your post to be upmodded.
I expect I'll be downmodded by whoever modded you up, but I have karma to burn so what the hell.

We abandoned Tarkin, but not because of VP3. It was an interesting crazy idea that simply wasn't workable.
Tarkin was an attempt to replace motion compensation with a directional 3D wavelets that could predict across time. It had... disturbing... encoding artifacts.
