Don't upload content with fansubs and try to keep the video resolution the same aspect ratio as the original (4:3 & 16:9). It's quite important to respect the original framerate as well, to protect the intended timing of the animation.

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 segments well over a minute long if possible that include elements that interrupt the flow (in the context of this website).
• 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 artifacts. 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 mp4/webm is mandatory.

04/04/2023 Update: Here's a new, updated version of sakuga encoder with a modern GUI and custom presets (thanks ftLoic). Click here and download the latest available version under "Assets". The old version is available below for archival reasons only.

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. (This is deprecated, see note above)

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

When encoding your clips keep the following in mind:

=For 16:9 video=
Keep the resolution round 848~854x480. Resolutions that are effectively wider can get away with a larger resolution while still sticking to 480 pixels of height, because enough users misunderstood (or were very cheeky about) the 480p indications so now it's just something we've already accepted. Your win, users.

=For 4:3 video=
Keep the resolution around 640x480.

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

Known Issues

• Recent versions of Avidemux sometimes show the wrong nominal framerate after encoding (such as showing 24.012... instead of 24.0). This is a minor issue that doesn't affect the actual framerate of the video, but it's recommended to use Sakuga Encode to avoid it.
• Blender Video Editor (VSE) has an unknown compatibility issue that can cause MP4 videos to get glitched/pixellated when viewing frame-by-frame or be unplayable in certain browsers. If you prefer to use Blender for editing, re-encode your video on Sakuga Encode after exporting to avoid issues.

If your video is failing to upload, check the following:

• Are you using a compatible file type and codec? (MP4 is preferred)
• Is your video above the file size limit of 70 MB? (subject to change, try to keep below 50 MB)
• Does your video have an audio track?
• Is your video bigger than 480 pixels of height?
