A quick updated comparison on my M3 pro:
- VLC 3.0.20 STILL couldn't do HDR or Dolby Vision and looked terrible
- Movist Pro handled HDR and DV very well, the UI isn't so pretty but it makes up for it with customisation
- Infuse did HDR very well and I slightly prefer the colours to any other app but I have a bug and so do a few others it seems where DV videos flash/flicker every now and then making it unwatchable (thread). Best UI out of the bunch but AWFUL customisation. Can't even change something simple like how far it goes forward when you click and arrow key. Deal breaker.
- Didn't try IINA, has very mixed reviews and no major releases for months
- Didn't try optimus player, seems good but also no updates in ages
Going forward Movist Pro is my main video player, coming from MPV on windows I need the customisation it provides. The price isn't too bad and it isn't an expensive subscription like Infuse.
