Google A few months ago, Google open sourced the VP8 video codec as part of the WebM video project, to create a truly Free/free unencumbered video format for the web as an answer to the non-Free/free patent-encumbered H264 format. Today, Google launched a new image format for the web, WebP, which aims to significantly reduce the file size of photos and images on the web.

You know, I'd tend to trust devs working on H.264 technology talking about their competitors just as much as Xiph devs talking about H.264.

Just sayin'...

Competitor? The very same guy also wrote a VP8 decoder for the ffmpeg project from scratch.
He's an active contributor to both worlds. I don't see him competing with his own software.

If you don't trust him, feel free to repeat his tests and compare the results.

He is a competitor. He is pushing X264 as the web standard for video, and he and other x264 devs are trying to get permission to dual-licence x264 so that they can charge money for propriety projects that want to incorporate x264. The fact that he and some other developers (he wasn't alone) wrote a vp8 decoder for the ffmpeg project does not change this.

No, good old Dark Shikaru has a little too much personal interest in x264 vs webm/webp for my taste. Also, why the heck did he use a motion video frame as source? Smells like a tailored test methinks.

I'll look forward to totally independant comparisons using a wide range of raw images (so that it won't favour either encoder) which can then be compared quality-wise between jpg and webp when encoded to the (near as possible) same file size.

Like I said earlier though, even if webp would prove to be a better format in terms of size/quality than jpeg I seriously doubt it will gain any traction. Jpeg dominates the web by being supported everywhere and being 'good enough' in terms of quality/size. I believe a new format would have to be so much better (quality/size, no submarine patent threat, permissive licencing) that it's simply a no-brainer to do the switch from jpeg even with the pain of transition, and I really don't see that webp is or ever will be that. Time will tell.

Dark Shikari doesn't care about "web video" per se, he's just interested in high quality.

And btw, x264 is *already* dual licensed and being sold. Lots of companies want it. And you know why? Because it's simply that good.

As another commenter said, if you don't trust DS results, do your own test. These conspiracy theories regarding DS here at osnews are quite silly to me.
(if that last sentence gets this comment downvoted, so be it. won't chance the fact that by constantly accusing DS of bias, you're doing nothing but actually showing *your* bias)

Oh, and regarding using a motion picture... here's what Dark himself said (yes, it's advisable to read all the comments to his blog post):
"That video is taken on 65mm film by a camera that costs more than most houses — it is higher quality than almost any image taken by any “photo camera”. I highly doubt your average Creative Commons images even have a quarter the detail that an Arriflex 765 can take."
