Convert Dolby Vision to MKV

[TheDreadPirate]

When you say it "streams DV fine", what do you mean by that? From Netflix or Disney+ or another streaming service?

Do you know what DV profile your file is in? Streaming services will use profile 5 or 8. Blurays are typically profile 7. Most devices smart TVs that can playback DV natively will usually only support profile 5 or 8. The bluray players will do all the work for profile 7.

Profile 5 should be in a mp4 container. Something about detecting it better. Profile 7 and 8 can be in either mp4 or mkv.
