Primatte Studio not undoing

Hi, I assumed if I took something too far and needed to undo my last action I’d be able to Ctrl+Z to go back a step but that doesn’t seem to work? How do I undo the last adjustment I made?

Hi Andi,

I believe you’ve stumbled into a Media Composer bug that has been fixed in new versions of the software. The bug is that undo of an effect param change is ignored when using keystrokes to undo the change but you can work past that by selecting Edit>Undo from the top menu in Avid.

Please let us know if this works for you.


Thanks Peter, yes, for workflow reasons I need to stay on this version. I will give the workaround a try, maybe I can map the command to the keyboard or a macro for speed.
Out of curiosity do you know which version it was fixed on?

Hey Andi,

I’m not sure off the top of my head when Avid fixed the undo issue but I’ll do a little research and share my findings.


Very kind, please don’t go to too much trouble, it’s just to satisfy my curiosity. Thanks!
