Is it possible to import on kitsun from anki or create your own video deck?
Welcome!
Yep, depending on what you want we go the following two options:
If you have premade anki decks you can import them from the import page (Sidebar - Tools -> Import), it will automatically upload your media for the deck as well.
If you want to create your own video cards you can do so with Subs2Kitsun. Here is a blog article about how to get started:
Note that this works on the premise that you consume the material and make cards at the same moment.
I already tried to do this, but only the audio files and images works. Is it possible to somehow make cards with mp4 files?
Sorry, I thought you meant cards from videos, rather than cards containing video files.
While technically possible, you’d need to create a layout with a
<video width="320" height="240" controls>
<source src="{{fieldwithvideofilelinks}}" type="video/mp4">
</video>
kinda element in it and it should work. I’m not sure whether the anki import accepted videofiles though, but if they are there (with a link) then it should work.
I’m afraid Sub2Kitsun itself does not support generation of cards with actual video inside it due to file sizes and other reasons (like copyright).
