slowing down (not converting) 30 fps to 24 fps at DVinfo.net

Hi all, thanks for the forum.

Am new here and new to video courtesy of the 5dmkii, so am a sponge at the moment.

I think I understand the process of converting 30 fps to 24 fps so that a clip stays the same length as the original.

Audio issues aside, if I shoot at 30 fps, is there a way that I can export all the captured frames at 24 fps, effectively "slowing down" (and making longer) the resulting clip?

- Copy raw captures from 5D Mark II CF card to desktop.
- Open in QuickTime Pro.
- Export as Apple Pro Res 422 (HQ), 1920x1080, stereo 44.1khz (this is a very fast export)
- Open in Cinema Tools and conform to 24p (instantaneous)
- Open in Final Cut, create new project, drag clip into browser allowing sequence settings to conform to clip.
- Add clip to Timeline and double-click to open in Viewer
- Add Effects>Audio Filters->Apple->AUPitch
- In Viewer edit the AUPitch settings Pitch->300 (cents, I believe, meaning 25 percent pitch correction)

Steven, I'm interested to know if you have found this to be a workable process, and if you have any examples of how it looks....
thanks

23.976/30 = 0.7992

Simply slow your video down to 79.92% and it will be 1fps in a 23.976 sequence.

If you are actually working with 24fps and not 23.976fps, then slow the video
down by 80%. This will slow down your video so you don't lose any frames and
your video will be longer.

I tried it in Premier Pro CS4 and it worked perfectly.

thanks Clint, will give it a try.

Just open a clip in cinematools and reconform to 23.98- no codec conversion necessary. Then edit inside of a 23.98 timeline in FCP.
