WebM is clearly a far inferior experience compared to gif on firefox: - at the start there is a stupid "fade in" effect. - the loading animation does sometimes not disappear even though the video has fully loaded. - the loading animation is generally annoying. Gifs just stop when bufffering and continue as soon as there is new data. - a useless control bar shows at the bottom on hovering. - Unlike gifs the video does…

>WebM is clearly a far inferior experience compared to gif on firefox

No it's not. I'm using nightly on linux so my experience may have differed somewhat, but 90% of gifs load just as fast or slower for me. Ever since I started seeing webM videos appear online I've enjoyed them immensely more than youtube videos or gifs because of the quality and loading times (they usually start immediately), and the fact that they're usually very short which forces them to be packed with the most in-demand content, but can be longer than a gif if need be. I'd take a webM over a gif any day of the week.

edit: and I'm running Ubuntu 14.04 on a laptop with an intel core i5 and integrated graphics and not experiencing any problems, but I'm also closing the videos after I watch them. The fact that they don't pause/stop when you scroll is kind of a minor bug that can be fixed pretty easily.

What other reasons were there to limit videos to 2 minutes, without audio? They certainly aren't technical limits. The commons reasons cited on 4chan are: 1. All videos with sound would be "screamers", where the audio would get really loud unexpectedly halfway through, as a simple troll. 2. 4chan is an _image_ board, not a video board. 3. the MPAA and other copyright holders would crush 4chan with DCMA takedown reque…

>what 4chan wants is basically better GIFs.

_And_ sound, as evidenced by anybody who posts links to youtube or soundcloud, e.g., /a/ or /mu/. Having such functionality directly in 4chan uploads would further the goal of anonymous ephemerality/content creation better than links to other sites. I can see your point if by "4chan" you mean "moot and site admins" due to the copyright concerns, but my feeling from other anons is that audio support would be awesome overall.

>You haven't been on 4chan much, have you?

If the novelty truly never wore off, every gif would still turn into cheetus after the first frame, and every link to youtube would still be Rick Astley.

Plus, think of your argument if we already had audio webms for their legitimate uses and had never known restriction. Would you give up audio on all webms just because of an occasional "screamer"? Would you give up all images just because some anons occasionally post shock pictures?

Has anyone had experience optimizing for webm? I really want to support this codec, but it's insanely slow in my experience. I'm finding that it's generally around 4x slower than mp4, but I've also had cases where it's taken up to a minute to encode a file where h264 take under 10 seconds. My use case is to have the best performance/quality ratio for a 30 second video under 3mb. These are my ffmpeg flags: h264: "-vco…

The last time I did any testing was about 6 months ago, but libvpx is terrible at multi-core. x264 scales pretty much linearly with more cores.

I am generally batch encoding thousands of short videos, so I just run the encoder in single thread mode, and create a queue for each core.

IME, VP8 is about half as fast as x264. If you are trying to encode a single video on a 24 core server, then it is about 20 times slower than x264.

WebM is a fantastic step forward. I prefer gfycat links over imgur gifs when browsing reddit (gfycat is a service that converts gifs to WebM). It does have minor teething problems (controls, loading animations, etc) but its advantages outweigh its negatives. WebP however for some reason hasn't gained as much traction as WebM. Firefox refuses to merge support, despite the fact it leverages the same library is WebM. I'…

Gyfycat does not use WebM, it uses mp4:

Take a look at gfycat: http://gfycat.com/CheapDecisiveChipmunk 30MB gif is a 17MB video that you can pause, resize, slow up/down. No fade No loading animation No bar

I'd say Google has its own share of responsibility for the lack of adoption of APNGs. Chromium doesn't support them out of the box.

I suppose because that requires using libapng instead of libpng, maybe?

APNG support can be implemented on top of regular libpng. I have the working code.

My hypothesis for the performance disparity is that h264 encoding is hardware accelerated and webm is not.

x264 does not use GPU hardware, so they're both using just the CPU. WebM fails to use more threads or 256bit or 128bit registers correctly.

recent versions of x264 do use GPU hardware via OpenCL, but the performance gain is questionable.

This is a very big moment for WebM. I feel 4chan has become the 'porn' industry of the internet. With VHS vs Betamax the largely deciding factor was which standard porn supported (this was again to a lesser extent with bluray). The general lack of adoption of animated png's is often pointed squarely on 4chan. Since it generated most of the web's viral funny content. And since most of it was in .gif, who needs to supp…

When is this "Porn decides video formats" argument going to die ? H.264 versus WebM wasn't decided by Porn. BluRay versus HD-DVD wasn't either.

I doubt that it really won the VHS/BetaMax war either.

OP's link is 404ing and moot's won't connect at all for me. There's no way HN took down 4chan. Anyone have additional info/a mirror?

HN mods should probably update the submission URL to this one: http://blog.4chan.org/post/81896300203/webm-support-on-4chan And you need to disable HTTPS Everywhere for blog.4chan.org since Tumblr doesn't support HTTPS :(

Tumblr does support HTTPS, just not by default yet.
