MP4s in Source and Programs windows are black (24.1.0 on Apple Silicon)

[SometimesY]

Running Premiere Pro 24.1.0 on Apple Silicon. Audio plays fine, but the program and source windows, along with the export window, are all black. No issues when I last used the project a few weeks ago (not sure which PP version that was). No recent posts on this matter, older solutions have no effect. After Effects 24.1.0 and Media Encoder 24.1 display the MP4 clips without issue.

Edit 2: I wanted to add a bit of extra info: I checked to see if I could change the render engine to software (greyed out) or see if running it via Rosetta was an option (no dice, at least via the Get Info window). Anything I'm overlooking? Open to any ideas!

Edit 3: tried resetting preferences. Reset everything. Still black on all three windows.

Hello @SometimesY,

Thanks for the screenshots and notes. The community could use more info about your system and especially the media you are using. Issues like this can be due to non-performant or faulty variable frame rate video. Please give us info according to this FAQ: https://community.adobe.com/t5/premiere-pro-discussions/faq-what-information-should-i-provide-when-a...

Hope we can help you.

Thanks,
Kevin

Hi Kevin,

Thank you for your response —I've compiled some additional info using the link you provided.

As of 12-12-2023:

Problem occurred after the latest update five days ago. I did save a copy of the project using the latest version and re-opened. Issue still occurs on saved copy. No error messages. No crash log.

Hardware/OS: MacStudio 2023, M2 Ultra, 192GB RAM, running Sonoma 14.2 (updated yesterday, no effect). Vanilla install of OS with Default Folder, MS Office, Adobe CC v6.0.0.571 installed.

Software: Adobe Premiere Pro 2024 Version 24.1.0 (Build 85) (updated 5 days ago)

Video format: H.264 codec in a MP4 wrapper (screenshot attached)

C2623.MP4
Resolution: 3840 × 2160
Data Size: 604.3 MB
Data Rate: 201.81 Mbit/s
Video Format: H.264
Audio Format: Linear PCM, 16 bit big-endian signed integer, 48000 Hz
Encoded FPS: 50
Data Rate: 200.27 Mbit/s

The encoded FPS is high, as we intended to utilize slow-motion effects on shots.

Interestingly, the Timeline window loads and displays frame thumbnails, which appear a moment or two after clicking on the timeline.

I discovered that I can get the video to appear (partially) in-app: if a selected clip in the Project window is double-clicked (to the right of the filename), it refreshes/flashes the Source window above and displays correctly (the Program window remains black, though).

Converting source movies via Media Encoder into several formats, then replacing the footage in the PROJ file, had no effect on the Program window.

Hope this helps! Let me know if you require a sample of the project file and/or source footage.

Edit: double-checked the info on the video clip in VLC. Attached a screenshot below.

Some additional info, via the Properties window in Premiere. It's that nether-week tween holidays and the new year, but fingers crossed for a solution or workaround soon!

What is the adjustment layer doing, what happens if you turn it off?

[SometimesY]

Should have mentioned that earlier —the adjustment layer is just doing some project-wide color correction. Toggling the visibility on and off, or deleting it, saving a new copy, and reopening the file, has no effect.
