Video format support (last update October 2021)

If you find your video can't play, or that your video will play but there's no audio, it's almost always because your browser can't play the file's video or audio codec. This is the case with HEVC/H.265 video and AC3 audio, which almost all browsers can't support due to licensing issues. Current state of browser support:

Will play almost any file that doesn't use AC3 audio.
Chrome and other Chromium based browsers (except Vivaldi/Opera)
Will play almost any file that doesn't use HEVC video or AC3 audio
Vivaldi and Opera
Will play few video formats (these browsers deviate from Chrome by rolling their own implementation of HTML video)
Will play few video formats
Everything else
Probably not a good option

So, if you want animebook to play the most video files, the Marmaduke all-codecs builds of chromium are your best bet, and you can install Yomichan on it (instructions below). Otherwise your best bet is Chrome, and you'll need to avoid using HEVC video or AC3 audio with it. And in my experience, while a lot of anime uses HEVC video, AC3 audio is relatively rare, so I've been able to get by with just using Marmaduke and occasionally having to avoid releases with AC3.

Marmaduke Chromium installation instructions:

  1. Find and install a Marmaduke all-codecs build of Chromium on https://chromium.woolyss.com. Make sure both the tags "Marmaduke" and "all-codecs" are tagged on the release.
  2. Enter the browser flag chrome://flags/#enable-clear-hevc-for-testing into your url bar and enable it in the page that shows up.
  3. Enable the Chrome web store, by manually installing https://github.com/NeverDecaf/chromium-web-store into Chromium (this is required because the Chromium build is ungoogled)
Note: I used to recommend Microsoft Edge with HEVC Video Extensions to watch HEVC video on animebook, but as of October 2020 the Microsoft store started charging money for HEVC support, so I removed it from the browser list. It technically does support AC3 audio though, unlike Ungoogled Chromium.

Automatic Anki Export (February 2021)

Animebook now supports exporting flashcards to Anki with a Chrome extension. It's meant to work together with Yomichan, so if you're interested, you can download it here.


To use the Animebook Chrome extension,

  1. Click the extension to open its settings
  2. Configure the Anki deck, model, and fields you want to export to
  3. Add a word to Anki using a tool like Yomichan
  4. Select and highlight the subtitle text you want on your card
  5. Hit the plus button
  6. Wait for the most recent card in your Anki to get a screenshot, audio, and text added to it
