What happens if I put my 24 fps footage into a 30 fps project

Dave,

What??? Are you aware that there are times when you know what you’re talking about but no one else does… this is one of those occasions.

If your project is 59.94i (29.97 interlaced) then pulldown will be added to the 23.98 footage to make it into smooth 30fps (like what happens when TV shows shoot film at 24fps, but have it transferred to data files at 29.97). Premiere will add the pulldown.

If the project/sequence is 30p…well, then 6 duplicate frames will happen in the footage and it will look slightly stuttery. Just a little. Nothing can be done about this…progressive to progressive frame rate conversions always just double up on a few frames.

Yes this makes the most sense thanks!

If on a single clip, use “Clip->Video Options->Time Interpolation->Optical Flow”
If on an entire sequence, when you are exporting, at the bottom of export window, choose “Optical flow” as the Time interpolation method.

It isn’t perfect, and if you’re a pixel peeper you might notice some odd artifacts here and there, but in the normal course of most applications no one will be able to tell. Hope this helps.
