Importing MPEG-2 from film source
I have MPEG-2 source footage originally shot on film. I need to create animation on this footage in AE 6.5 and export at 29.97fps. Normally I would import my film source footage, then remove pulldown, animate in a 23.976fps comp, and finally reintroduce 3:2 pulldown during my render for a 29.97 QuickTime. However, I can’t seem to conform this MPEG-2 footage to 24fps(23.976fps). Therefore, my renders from AE have artifacts such as jerky motion every 5 frames, differently perceived frame rates between footage and animation, etc.
Does anyone have experience with this issue? What is the best way to conform MPEG-2 film footage to its original frame rate of 24fps? I appreciate any help.
Thanks,

I just found that when taking one of these clips into QuickTime Player, I can open “Properties/MPEG2 Video/Visual Settings”, then uncheck “Preserve Aspect Ratio” and manually change the Current Size from 720×404 to 720×480. When I do this, the frame rate changes from 30 fps to 24 fps.(?) I have no clue why a change in image size and pixel aspect would affect frame rate – maybe this is related to the MPEG-2 spec. I think my problem is solved for now, but if anyone has more insight into working with MPEG-2 files with 24 fps source footage, I’d appreciate any shared knowledge or experience.
Thanks,
Mike
