This repository is only for the frontend delivering the videos to the end-users. I believe you want to open the issue here: https://github.com/voc/voctomix - which is the video mixing software used by us to produce the recordings.

Sorry for the issue, but i'll close this one because "can't fix at this point".

Just discovered github allows me to transfer that issue to another repository, TIL.

ah, sorry for the wrong repo. I did not read my own notes properly 😅
