Shouldn't 60i on 24p timeline be slow-mo?

I've put a 480/60i video on a 23,98fps timeline on FCP expecting to see it in slow-motion. But I am not. What's wrong in this equation?


* I'm using HVX200, shooting SD on tape.

Doesn't work like that. It will interpolate it out to only 23.98 fps. you need to do a time remap to get it to go slo-mo.

That's weird, because when I'm shooting 720p60 in a P2 card and put it in a 24p timeline, I do get slow-mo. But when I try it with a 480i60 tape recording, I don't.

Over and under cranking only works on P2 cards. Not on tapes.

It will work but you just have to tell the clip to not do what it's doing which is interpolate to 24fps. Access the Speed controls for the clip and then reset speed to about 40%. Turn off frame blending. You should now have approximately 2.25X slow motion. Not going to look amazing but definitely better than doing the same thing to a 24p clip because you actually have more captured motion to work with from 60i.

But only if you shot in pN mode, right? If you shoot in 720P mode, instead of 720pN mode, then I would wager it would perform exactly like your 60i clip is performing.

The BETTER way to do this is duplicate the file that is 60i that you want to be 24, open THAT clip in Cinema Tools and change it's playback rate metadata to 24 fps and import THAT clip to FCP. That way you use EACH frame for slow motion. By using the Speed method in FCP, it interpolates the "in between" frames.

No it doesn't actually- the effect is identical. All you're doing is overriding the frame rate conform and telling FCP to go back to using all the available frames.
