With the latest macOS 13.4 update, the H264 codec 120FPS is no longer working and users are instead greeted with the ‘Render job failed as the current clip could not be processed’ or ‘The clip could not be decoded correctly’ error message. We tried many different software including QuickTime/Final Cut/DaVinci Resolve and all exhibit the same behavior, so the issue is definitely on the OS end.
Moroever, the affected clips are being shown with red ‘Media Offline’ indicators and as soon as the software comes across a XAVC-S or H264 codec clip, the software is unable to carry out its tasks any longer. In some cases though, we got the audio of the entire clip [even of the affected part] but the video was all black. So this begs the all-important question: is there a fix? Let’s check it out.
