Someone? Any advice?
Does this occur in brand new projects or just ones you updated from 12.0? Let us know.
Thanks for the reply, Kevin.
The projects were created in older versions of Premiere, after updating the software we did not make new project files.
Do you think this could be the reason for this behavior?
For verification I created new project files in the current version of Premiere and imported sequences and bins from old projects, I'll try to work this way.
I'll let you know by the results, whether this solved the problem.
The project file was created in the current version of Premiere, the media is reimported, the bins and sequences are re-created, nothing came from old projects.
The situation was repeated.
And as usual - no system, both automatically generated and manually assigned keyframes can be lost.
Below 2 screenshots - before and after the disappearance. Here automatically generated keyframes that were manually adjusted.
Before disappearing, I just switched to another clip on the sequence.
I will be glad to any suggestion.
