Export Framerate: What's The Difference?
on Dec 6, 2015 at 12:04:16 am

This is something that's always been a curiosity to me. Say I've filmed something in 23.976 FPS. My project includes only video, no generated media t all. I understand that changing the project framerate makes a difference in the editing process. But since all the source footage is 23.976 FPS, what would be the difference if I set the export rate to 24 FPS, or 30, or even 60? Would the exported file have any visible difference? If so, what? Surely, footage that is 23.976 can't be viewed at any higher framerate than what it already is. Thanks in advance.

The exported video would contain more frames that were synthesized from existing frames by blending them to create new ones. This happens all the time for every motion picture that was recorded at 24p but must be converted to 29.97 for viewing on an NTSC TV.
