Recommended encoder: ffmpeg
I will not be covering how to use this encoder. Our staff's encode settings are stored in the repository.

Hint: You can use our comfy encoding script.

Check out this page for information about how to find good video sources.

• Your video must not be larger than 40 MB unless the video is for some reason longer than 1.5 minutes, then ask Quad for details.
• The average bitrate of a video must not surpass 3.5 mbit/s, keep it below 3 mbit/s if possible.
• The max bitrate of a video should not surpass 4 mbit/s.
• Use two-pass encoding if possible.
• Videos must be 720p at most. Videos larger than 720p should be scaled down to 720p.
• Videos must be in a WebM container and use the VP9 video codec.
• You must use the Vorbis audio format. This may change when Opus support in browsers improves.
• Audio should be normalized to -0.4dB.
• Videos may not contain subtitle tracks (Firefox doesn't cooperate well with these).
• There should not be any black frames at the start or end of the video (unless it's a fade in/out, then it can have 1 black frame).
• Using the encoding settings provided in this repository does not guarantee that your encode will be accepted.
• Filenames should be in the format "Title-AnimeSeries.webm" (e.x. "Opening1-GurrenLagann.webm").

Your encode will be checked by staff, for details about the process, check the QA page

• 3 mbit/s is a max, not a target. For videos that could make do with 1.5 or 2 mbit/s, try to use that (i.e. endings that are pretty much just a slideshow).
• Videos should not have hardcoded subtitles if possible. We can actually display .ass subtitles, so use them instead.
• Easter eggs are pretty much exempt from the above terms as long as quality is somewhat acceptable and the bitrate isn't above 3 mbit/s. We're not picky about that as long as they're not complete crap.
