These are the same rules we have for gifs. Don't upload content with fansubs and try to keep the video resolution the same aspect ratio as the original (4:3 & 16:9).

A few other things to note:

• webm is natively supported on Mozilla Firefox, Google Chrome and Opera. Other browsers will require 3rd party addons.
• This one is obvious but, don't upload entire episodes of shows.
• When uploading cuts, try and split them up and not just upload 1 minute long segments that include stills and pans.
• Do not make video files larger than 480p in resolution, we want to have content viewable on most screens.
• Try to keep the bitrate high, we don't want videos with compression artefacts. It may take a bit of experimentation to find the right balance.
• Most importantly, strip the audio & subtitles from your file since we don't allow webm videos with audio (or subs) in them.
• Currently the booru only supports the vp8 codec for webm files.

Uploading webm is not mandatory, you can still continue to upload gifs. It's just now we have a way to have quality uploads in a format that's not 20 years old.

04/05/2014 Update: We now support the mp4 container. Much like webm, files uploaded with audio will be denied. Same rules as above apply. And while not mandatory, here's an easy tool for newbies to encode their mp4 files for the booru.

• For now we only support mp4 files encoded with the 8bit h264 codec. Sorry 10bit.

When making webms and mp4s please keep in mind the following aspect ratios.

=For 16:9 video=
If BD/HDTV: then make 854x480 or 712x400
If DVD/SDTV: then make 712x400 or 640x360

=For 4:3 video=
If BD/HDTV: then make 640x480
If DVD/SDTV: 533x400 or 480x360 (You can make 640x480 if it looks good enough)

SDTV - 'Standard Definition' So something that is not a HD source etc..

Try and avoid uploading videos with pixellation and lossy encoding issues.
