The project frame rate is 30fps but the trouble is a lot of my sequences are at 25 or 29 for some reason. Currently to correct this I have to go right-click > Sequence Settings > change frame rate setting to 30 > OK. Is there a way to do this faster via scripts or actions or similar? It's tedious.
I set a keyboard shortcut for sequence settings to save a right-click.
ExtendScript can change a sequence's settings, including frame rate; I'm not sure what you mean by 'project frame rate'?
If you "sequence-ify" a project item (drag it onto the new sequence button in the bottom edge of the Project panel), the created sequence will have the same frame rate as the project item with which it was instantiated.
By frame rate I mean the Timebase attribute of the sequence. I'm trying to set them all to 30fps.
You can definitely change that.
The source of my confusion was your use of the term 'project frame rate'; PPro projects don't have frame rates. 🙂
Sorry I meant of the sequences.
