This behaviour should be changed
mkv is perfectly playable
Convert to mp4 maybe only needed if browser throws error etc
I am uploading 2.4GB mkv file and it takes forever to get it displayed
Now ChatGPT 5.5 identified this issue and i am trying to patch it but this should be default behaviour
just upload a big mkv file into a video preview field
edit
ChatGPT 5.5 was able to patch it to skip this conversation and it works perfect
