Prores Color Bending & Other Problems

Thanks for this tip as well. I would have never thought of rechecking this checkbox on the next update (and i've been updating alot recently, due to the istability of AE with the M1).

Anyway - you have proven to be a very helpfull dude indeed. 

thanks alot

Oh interesting! So disabling the hardware acceleration also fixed the banding problem. 
Hmmm, seems Adobes implementation of the M1 hardware acceleration is even more broken than I thought if it also introduces banding. 
Fortunately it's easily turned off, but be aware, whenever you update After Effects (or sometimes after a major crash) this setting will return to the default ON state.
It's a shame Adobe thinks this problem is not serious enough to default this setting to OFF instead of ON and it's even one of the few (if not the only) setting that is not migrated when updating after effects. You know, that one setting they know is broken, that's the one they will default to and force upon you every time you update.
This problem is clearly not very high on the priority list. 

OMG , Disabling hardware acceleration in the import preference pane DID solve the problem!

It also solved the  'banding' (gradiants showing bands with hard edges) problem

Man,  that was the single most usfull advice i got in a long time....

Thank you so much!

Much respect
