How to change frame rate by speeding-up/slowing-down?

Hi,

I always shoot in 24p. Now I have access to some really nice drone footage, which was shot in 30fps, which I want to use in a 24p project. How can I change the frame rate of these clips to 24 fps without converting, but just by slowing them down? When I use this material in my project I need to conform it by one of the FCPX methods "Floor", "Nearest Neighbor", "Frame Blending", or "Optical Flow". All of these somehow process the material. That is not what I want. I basically just want to change the playback information for these clips without really touching the material. That is not what I want. These are all nature shots, so it doesn't matter if they playback a little slower.

I found a tool that does exactly what I want, but it only works with Quicktime movies :-/

Lossless Frame Rate Converter (free) download Mac version

Any help is appreciated.

Regards,

Nippie

If I understand correctly what you want is what FCP X calls “Automatic Speed”.

I am not at my mac but I think it is in Modify->Retime->Automatic Speed or something like that.

Hi fox_m,

thank you for your reply, but I think you explained exactly what I DON'T want to do. Let me give you an example: Let's say I have a 2 second clip at 30fps (which has 2*30=60 frames in total). I do what you said and put it in a 24p project and let FCPX handle the conforming. I will end up with a 2 second clip at 24fps, which has 2*24=48 frames in total. That means FCPX converted 60 frames to 48 frames by skipping or merging frames just to keep the clips length at 2 seconds. THAT IS NOT WHAT I AM TRYING TO ACHIEVE! I want to keep all 60 frames and just adjust the clip length. So my result would be a 2 seconds and 12 frames long clip with 24fps.

Final Cut handles all of this ("conforming") automatically. All you have to do is set up a Project that's 24p. In the open

then add your footage to the storyline...
