Has anybody noticed a green flickering hue with Prores 4444 material?

Preview and rendering have random flickering frames.

I noticed this in my latest project. Did not happen before with other Prores material. Tested both with the client's original and re-encoded versions. Colour management or anything does not seem to affect it, but...

Turning off the hardware decoding option in Settings seems to help:

Settings - Import - Video Footage - deselect hardware accelerated decoding box.

Just lost two days' worth of hours.

I am seeing this same exact problem appearing in Adobe Premiere Pro. ProRes 4444 clips, Premiere Pro 23.6.0. Mac Studio M1 Max running macOS Ventura 13.5. When I play files they appear tinted green, when I pause they are tinted magenta, when I scrub through the timeline I go back and forth between green and magenta tints. Makes Premiere completely unusable for color when using ProRes 4444 files.

Thank you for the information

Do I understand correctly, we must upgrade to macOS Ventura to get a fix for the green/magenta flickering!? Can you confirm if all Adobe products are fully compatible with Ventura, please?

My previous post (Aug 11) was moved to this thread. However, my problem with Proreas files is not the chroma flickering, but a luminance/gamma drop on the first frame on the timeline (may be related though). Is there any information/solution for this yet?

I can't use AE V26.3.0 for professional work until Prores problems are addressed and fixed. The last functional version (for me) is still V23.2.1. All later versions have Roto Brush or Prores problems. This really starts to feel your date prediction (2923) is true [apologies for the sarcasm] 😁

Hi all,

Thank you for your continued patience on this. Apple has informed us that a fix for this issue was released with macOS Ventura 13.5 on July 14th, 2023.

If you continue to experience flickering with ProRes import after updating macOS to 13.5 or higher, please let us know as soon as possible.

Thank you again for reporting this issue,

Mac Studio M1 Ultra

macOS Monterey Version 12.6.8

After Effects 23.6.0

The new update did not fix the flicker problem with Prores 4444 and Prores XQ.

No hardware encoding or decoding in preferences.

Metal GPU acceleration.

OCIO Color management - ACES working space.

Import a Prores file and preview it in the timeline. Increase the contrast and lower the gamma to make the fault more visible. The frame you start previewing from and the first frame in the timeline will have dropped luminance/gamma levels. Advancing frame by frame does not make the level drop.

The rendered Prores file has this fault.

Not good. Trashing 23.6. and reinstalling 23.2.1.

Please Adobe. Fix this.

Where can I claim a refund for my subscription fee?

I have experienced chroma flickering in AEwith the Mac Studio and M2 chip. The same footage playing on an iMac Pro with Intel chip is flicker free.

Hi all,

Thank you for your reports about this issue, and for your patience. We are currently working with Apple to get this issue resolved for M1/M2 machines. In the meantime, you should be able to avoid this issue by disabling hardware encoding/decoding of ProRes files. Those preferences for After Effects are located in:

Preferences > Import > Video Footage > Enable hardware accelerated decoding (requires restart)
Preferences > Output > Enable ProRes hardware accelerated encoding, if available

Please let us know if the issue persists with those preferences disabled.

Thanks again for your patience as we work to address this issue,

- John, After Effects Engineering Team

Help!

Hardware acceleration is turned off in settings. Prores import is still flickering on AE 23.4 with M1 Mac!

Is it just me... or?

Mac Studio M1 Ultra

macOS Monterey V12.6.5

After Effects V23.4

Just got a client's comment for flickering renders. Nasty surprise.

Nothing helps - Clearing caches. Color management on or off (Adobe and OCIO tested both). Hardware acceleration on or off. Restarting Mac.

Had to downgrade back to version 23.2.1 which I know works.

Anybody else experiencing this?

Hello,

Thank you for reporting this issue as well as supplying the details of your AE installation and system.

Would you be able to supply us with a version of this project to try to reproduce the problem internally? I know that sometimes isn't an option depending on the project/client. If you can, posting them on dropbox or your creative cloud shared space and send a link would be helpful.

All the best,

I'm having a big issue with ProRes 4444 on Apple M2 Max -- after upgrading my Laptop to Apple M2 Max. Aftereffect is unable to render ProRes 4444 without color shifts/glitches flickring. This issue is happening only with ProRes 4444 and ProRes 4444xq. Every other ProRes file works fine.

I have 10 shorts to finalize - I'm getting stuck because of that,

Please help this a desprate situation that is already consting me a lot time.

Yes, known issue.

Turn off Hardware Acceleration in the Preference>Import pane.

Be aware, every time you update After Effects, this setting will reset to the default on setting.

AE 23.2 unfortunately still produces green flickering with hardware decoding on on a M1 Mac.
I know this is a known problem and the Premiere team needs to come up with a fix or something.

So what I’m wondering is WHY is this setting still on by default, since it’s clearly not working.
But even worse, off all the setting that are migrated from 23.1 to 23.2 THIS is the one that is not migrated?
So the ONE setting that is KNOWN to be broken is deliberately (and silently) reset to the faulty default state.
Why? I don’t understand. Feels like sabotage.

Please, if something is known to be not working, don't have it on by default and certainly don’t silently switch it back on when it’s already set to off.

Losing a lot of time here checking and re-rendering VFX because it…
