View Full Version : mixing different formats with slowmotion in one FCP Timeline

Hi,


I'm working on a project where I'd like to mix different recording formats in one timeline. Specifically I'd like to do the majority of the shots in PAL 1080 25p.
For the slowmotion shots I would like to use the NTSC 720 60p format and have it play back at 25 frames. I don't wan't to use overcranking, because I need the sound to be recorded with the slowmotion.
In final cut pro I encounter the problem that when slowed down and played back in a timeline set to 25p, the 60p clip is as choppy as any other 25p clip slowed down.
I can slow it down beautifully in a timeline set to 60p, but when I import my 25p footage here and export it to 25p, frames are missing and the overall video get's messed up.

Is there a setting that allows me to simply import a 60p cliip to a 25p timeline and simply play it back one frame per frame at 25 frames, resulting in smooth slowmotion?


thanks,

David

Create 2 sequences.

MAIN SEQ: 25p
SECONDARY SEQ: 60p

Set up your slow motion stuff in the Secondary Sequence. When you've got it the way you want it, drag the Secondary Sequence into the Main Sequence. This is called "Nesting Sequences".

No can do. FCP will not allow you to nest a sequence with a different editing timebase

I dont know if this is related but I had a problem in Vegas Pro akin to this and solved it by clicking "disable resampling" in footage properties. See this thread here: http://www.dvinfo.net/conf/what-happens-vegas/143919-ghosting-normal-motion-blur.html

Unfortunately FCP lags behind Vegas in its options for telling it how to treat clips, so this isn't possible.

If I understand correctly, that means I have to convert the footage to ProRes, then conform it in Cinema Tools, then import it into my timeline.
Or I can export it from Quicktime as Image Sequence, re-import it into quicktime with new frame rate, export it, import it into the timeline and re-sync the audio...

Man, and I had hoped to get away from countless hours of re-rendering and timelines with different formats which are usually sluggish for editing...
So there is no way in FCP to simply have a clip played back frame by frame in the sequence settings, ignoring the original timebase?

Youre propably on a mac right? If you have a change you could try downloading Vegas Pro trial and test to see if you get different results.
