I’ve had the same issue converting MOV files running thru the 4K UniFab upscaler, . Worked fine a couple of months ago, now my Windows Media Player or Movies and TV player does not recognize the files although UniFab completes them. Media Player says the file is not compatible although VLC plays it just fine. Not sure where the change occurred: Windows or UniFab but it is frustrating. I’m using the H264/MP4 setting. I see a couple of critical errors in the logs, not sure if they are relevant. I’ve submitted a request for tech support, we’ll see if I can get an answer.
