“Interpret Composition” or equivalent script/workaround:
When working with vendors supplying things like matchmove or 3D, I often get projects back in the wrong framerate. Basically, imagine I have a comp which is 100 frames long at 24fps and has tracking data for each frame. Sometimes the comps I get back are, for example, at 30fps. It’s still 100 frames long, and all the data lines up per frame, but it’s all at the wrong framerate, so the shot in this case would be playing faster than normal.
At this point, I’ve got two options:
•I can go back to the vendor and say “Hey! Fix this!” which will take 24hrs at least, and may still not be right. Or:
•I can copy the keyframe data into a text editor and change the framerate header to the proper frame rate, and paste it back in. This works pretty well, except if there are many many layers in the project.If the composition was a footage layer, the “Interpret Footage” dialogue would solve the problem. However, no such option exists for compositions. Merely changing the composition’s framerate would leave me with extra frames and data that doesn’t line up.
•The RD_Compsetter script is very useful for related tasks, but unfortunately just changes the comp framerate as you would in Compositor settings.
What I’m wondering is this: Is there a way (probably a script) to “Interpret” the composition and all keyframe data in it as a different framerate?

You could precompose the tracked footage and leave the inner precomp’s frame rate wrong, change the outside containing comp’s frame rate to the correct frame rate, and use Time Remap to adjust the duration, correcting the frame rate.
