Shoot 30fps change to 24fps slow mo in FCP??

I'd like to get sound with my slow motion... so I would like to shoot 30fps and then in FCP some how have the clip playback rate be changed to 24fps which would give me slow motion. I could then fix the sound with a speed change.

Does anyone know how to do this?

Changing speed - just gives your frame blending - not same as shooting 30fps played back at 24fps.

Exporting it to 24fps and reimporting at 24 - doesn't work - as it just dropped the extra frames and plays back at normal speed. Help?!

I know there's a way to do it in cinema tools but haven't tried it. You could also export it as 100% jpg frames in it QT Pro and then open the sequence, also in QT pro, at 23.976 fps. Then save the movie.

I'm sorry but I can not get this to work. Anyone else know how to export and re-import footage from 30fps to 24fps (slow motion). Thanks.

1. Find the Quicktime file in the Finder (not in FCP) and double click it to open it in Quicktime Player.

2. Choose File/Export

3. Change the popup at the bottom the the Export dialog to "Movie to Image Sequence"

4. Click Options

5. Select TIFF, or JPG - small window opens

6. Click Options (within the small window). Tiny Window Opens. Set the quality to the best, and the bit depth to the best.

7. Click OK in the tiny window

8. Make sure the frame rate listed matches your source frame rate (29.97fps) Click OK in the small window.

9. Make a new folder where you want to save the (very large) frame sequence. This is a temporary save - you can trash it when you are done.

10. Click the Save button in the Export dialog - the frame sequence will export to your folder.

11. Close the original movie.

12. Select File/Open Image Sequence

13. Find the first frame in the image sequence you created in the folder you created. Select it and click Open.

14. A small dialog pops up. Select the desired frame rate (23.976) and click OK.

15. The movie opens in a new window at the desired frame rate. Save the movie.

16. Save the movie or Export it in the desired codec.

Note that this process involves two compressions and can slightly reduce the quality of the movie. There can also be some slight color shifts that need to be corrected. And time code is lost.

That other technique using Cinema Tools may well be better but I have not explored it.

Thank you very much Eric. I will give it a shot first thing tomorrow.

I do enjoy recording sound with my slow motion - like crashing waves. Thanks!

UPDATE - IT WORKED!!! WOW thanks... I missed a step or two trying to do this myself.
