I just discovered something that VLC REALLY didn't like to play. A 4K50fps JPEG2000 YUV444 12bit lossless ~48 GB video that was only 1 minute long.

To be fair the bitrate of the video is insane at ~5700 Mbit/s. The bitrate is so insane that you should really consider using an NVME drive for playback.

MPC-HC could kinda play it but only with extreme stutter and lag. My CPU (Ryzen 9 5900x) was completely maxed out.

I think you need hardware acceleration for a video like this.

JPEG2000 = not lossless

JPEG2000 supports both. That's why I specifically said that the video is lossless

Right! Sorry, I assumed this was regular JPEG
