AMD h.264 Encoder Issue with FCP 11 and FCP 2.1 for iPad

I’m recording a video on one of my device(ROG Ally X) that uses AMD h.264 as hardware encoder on OBS. The video can play using Quictime without any issue.


When I import the video to FCP 11 or FCP 2.1 for iPad, I encounter same issue where the media is just black! This was working before FCP 11 and FCP 2.1.


I tried to isolate the problem

  • I tried recording a video to my other windows device using OBS using NVIDIA encoder (NVENC), and I’m not encountering the issue
  • I tried recoridng a video using my Macbook and OBS using the Macbook encoder (CBR), and I’m not encountering the issue
  • I tried to use the same device (ROG Ally X) but I changed the encoder to software x264, and I’m not encountering the issue


So I believe the issue is with the latest FCP version (11 and 2.1) handling of AMD h.264. This is really frustrating, if Apple was not able to test this kind of scenario before going live with this version of FCP


My workaround now is to use iMovie(No issue using iMovie) just to save again the video and use that new video on FCP. (Really a hassle)


Anyone encountering the same issue and a better workaround?

H.264 can be recorded in a multitude of ways. There are many parameters that can be tweaked. I think we'd need to know the specifics of the H.264 files the ROG is recording. Not all H.264 files will play in all video playback hardware/software. It's not a universal thing. And no software vendor is able to test every scenario and every combination of software hardware in the universe. It's too overwhelming of a task.
