The add-on can be used to convert videos (or audios) with subtitles to Anki. The video will be split into separate scenes/phrases. It was inspired by subs2srs.

HOW TO INSTALL (ANKI 25.02)

If you're on Windows or Linux, installing the add-on with the code should be enough to make it work, but it's recommended to additionally install ffmpeg.

If you're on Mac, it's better to additionally install mpv and ffmpeg via brew and restart Anki. Otherwise, Tools > Generate Mobile Cards might fail to encode mp3 and mp4 and will only work with opus and webm, because the mpv version that is packaged with Anki might not have libmp3lame and libx264 encoders built-in.

HOW TO INSTALL (ANKI 2.1.49)

1. Install the add-on.
2. Install FFmpeg from http://ffmpeg.org.

• On Windows it can be downloaded from https://www.gyan.dev/ffmpeg/builds/
• On macOS it can be installed using brew - https://trac.ffmpeg.org/wiki/CompilationGuide/macOS#ffmpegthroughHomebrew, i.e. install "brew" and then run "brew install ffmpeg".

3. Download mpv videoplayer from https://mpv.io

• For Windows, use https://sourceforge.net/projects/mpv-player-windows/files then click on "stable" or "64bit/32bit" subfolder and download mpv from there.
• For Linux, mpv might be already installed alongside with Anki sometime ago.
• For macOS, mpv can be installed via brew either by using "brew cask install mpv" to quickly install the latest binary version or "brew install mpv" to compile and install mpv from source.

4. For Windows, update the PATH environment variable in the User or System variables by adding folders that contain mpv.exe and ffmpeg.exe. Here's a short guide how to update the PATH environment variable on Windows 10 - https://www.architectryan.com/2018/03/17/add-to-the-path-on-windows-10/ - or a quick screencast - https://streamable.com/2b1l6
5. Restart Anki.

Another possible method to install mpv and FFmpeg on Windows without manually updating the PATH environment variable is to use scoop or https://chocolatey.org.

HOW TO USE

1. Tools - Generate Video Cards... (Ctrl+M).
2. Select Video and Audio.
3. Select Subs 1.
4. Maybe change some other options.
5. Select Deck and Model.
6. Maybe click on Preview to see how many cards will be created.
7. Click Go!

In the Phrases mode, the add-on will only use the subtitles' timings to generate cards, i.e. everything that doesn't have subtitles will be ignored like the start of the video or scene changes where usually no one speaks and there are no subtitles.

In the Movie mode, the add-on will change the subtitles' timings to make them continuous to be able to watch the video from start to finish without missing anything, i.e. the end time of each line in the subtitles will be changed to match the start time of the next line.

HOW TO REVIEW ON MOBILE

1. Tools - Generate Mobile Cards... from the main window or Edit > Generate Mobile Cards ... from the card browser window
2. Export an apkg file or sync with AnkiWeb.

For AnkiDroid 2.17, if you want video on cards, the "subs2srs (video)" note type is recommended as the "movies2anki" note type may not look good.

A slightly updated version of the card template is available at https://ankiweb.net/shared/info/2061725225 ("Learn German A1: Nicos Weg").

YOUTUBE VIDEOS (OUTDATED)

This is how it may look in action using movies2anki card template.

ADD-ON CONFIGURATION

It can be edited via Tools > Add-ons > ... > Config.

The "preferred languages" can be set similarly to the mpv.conf file below. If it's not empty, it'll be used to select automatically audio and external subtitles if there's more than one (while making a new deck of cards).

{
    "audio fade in/out": 0.1,
    "join lines with": "<br>",
    "join sentences with": "<br>",
    "preferred languages": "",
    "video encoding settings (webm)": "-c:v libvpx-vp9 -crf 30 -b:v 0 -c:a libopus -b:a 64k",
    "video extension": "mp4",
    "video height": 320,
    "video width": -2
}

MPV CONFIGURATION

The add-on now remembers the selected audio stream (that was used to make a new deck of cards) and adding 'alang=eng' or 'aid=1' to mpv.conf is no longer needed.

---

If the video file contains multiple audio streams, it might be useful to create mpv.conf with alang=eng to select the English audio track by default. For example, mpv.conf can look like this:

sub-visibility=no
sub-auto=fuzzy
slang=eng
alang=eng
audio-file-auto=fuzzy
save-position-on-quit=yes
autofit-larger=100%x100%
geometry=50%:50%

It can be downloaded from this link - https://gist.github.com/kelciour/dbb573812e9a45eaa7d5b123f1ccf822

• For Windows, mpv.conf can be added to the same folder as mpv.exe or %APPDATA%/mpv/mpv.conf, i.e. C:\Users\USERNAME\AppData\Roaming\mpv\mpv.conf
• For macOS & Linux, it'd be ~/.config/mpv/mpv.conf

All the options can be found in the mpv manual - https://mpv.io/manual/master/#configuration-files | https://mpv.io/manual/master/#options

ADDITIONAL INFORMATION

The add-on doesn't generate any audio/video files by default. Instead it can play a part of the original video/audio file with mpv video player using --start and --end options.

If the original video/audio file has been deleted or moved to a different folder, the add-on will try to find and play video/audio from the collection.media folder that were generated using Tools - Generate Mobile Cards option.

By default, new cards will be added to the deck with the name of the video file. It can be changed by selecting a deck from the list of existing decks or by typing a different name for the deck.

Set "Gap between Phrases" option to 0.0 to split subtitles by sentences or disable it to prevent joining subtitles into sentences.

The add-on contains 4 default note types:

• movies2anki (add-on) – Video + Audio
• movies2anki (subs2srs) – Picture + Audio
• movies2anki (subs2srs - video) – Video + Audio (desktop) / HTML5 Video + Audio (mobile)
• movies2anki (subs2srs - audio) – Audio

DEFAULT HOTKEYS

R – replay
Ctrl+R – replay video

[ - replay the previous card and the current card.
] - replay the current card and the next card.
Shift+[ - join the current card with the previous card (and remove the previous card).
Shift+] - join the current card with the next card (and remove the next card).

, – subtract 0.25 ms. from the start time
. – add 0.25 ms. to the start time
< (Shift+,) – subtract 0.25 ms. from the end time
> (Shift+.) – add 0.25 ms. to the end time

EXPORT CONDENSED AUDIO

Open the card browser, select a few cards that were generated by the add-on and click Edit - Export Condensed Audio. The cards with the same Path field will be joined into a single audio file.

The "Store temporary audio files in the collection.media folder" option makes sense to check if you intend to later use, or maybe already used, Tools - Generate Mobile Cards to review cards on mobile.

With the full movies or series, maybe try it in a new Anki profile (File - Switch Profile) by generating a new deck of cards with "Gap between Phrases" set to 1.25 or 1.75 and "Pad Timings" set to 750ms or something similar.
