I have the new Macbook pro M1 and the QT Gamma Cube isn't working anymore. when i apply the lut it just turns my entire video black. can't see anything audio only. Who else is having this issue or know a fix to it.

Did anyone find a fix for this? This issue has just started happening to me out of nowhere.

I found a part solution. When I change in the preferences to Software encoding away from METAL it allows the LUT to work and be previewed but the play back is highly jittery and does playback smoothly in QT when rendered out.

Anyone find a solution to this problem yet? Or has anyone developed a LUT that would solve the Adobe QT LUT problem. I am working on a M1 Mac aswell. When I am on METAL the only option that allows smooth playback in QT it only goes to black.

Thank you jakem, I've just tried to change the project settings to Mercury playback and it works.

So it seems to be METAL related.

Annoying because I already can't export with hardware encoding in Metal.

The option here would be to edit with the render system in Metal in order to have a smooth playback and then switch to Mercury Playback before exporting with the LUT. Tricky...

Hi Marco,

Sorry for this! Are you sure the LUT is installed in the proper directory? Or have you installed it in the app package? Let us know! Hope we can help fix it.

Thanks,

Kevin

definitely am having the same problem with this. Usually we just select the lut option and it would fix the colors of the video with the Intel version. But now theres no preview at all and when exported, only the audio gets shown with a blank screen. Could it possibly be the M1 Beta problem?

First thing, are you able to work with any other LUTs on that machine?

yes other Luts work, but for some reason, the gamma lut stopped working. Maybe it's because it's a beta version for the M1 macs?

Perhaps, I know some features and effects aren't fully functional yet with the M1 from what's being reported. Including engineer/developer-team replies.

Where do you have that parked on your machine, also?
