60fps-24 or 60fps-30??
 

Hello,

I own a 5D, and ordered a 7D which will be here next Monday. BUT, due to some last minute scheduling conflicts, I HAVE to plan out my shots now (meaning whether to shoot the project all in 30fps, or 24fps) before I have a chance to test out the 60fps on the 7D.

My question is this: Which conversion will produce the more smooth slow motion 60-24 or 60-30 or is it indistinguishable??? I will be using Premiere cs4 and Prospect HD to edit.

Thanks for any help.

I shoot 60-30 mainly for stock video, most of the buyers I sell to are working in a 30fps timeline. Frame rate is really governed by final use of the footage.

If your work flow is correct then a frame is a frame..

Think about it.

If you shoot 10 seconds at 60p. Then playback all 600 frames on a 30p timeline, it will take 20 seconds to play your footage.

Now, how long will it take to playback all 600 frames in a 24p timeline?


25 seconds...

Thanks.. i guess what i'm after, is if the 7D's 60p more dynamic conforming it to 24p or 30p? Which looks the best?? Or does it not really matter, because they are indistinguishable??

I find the 24p studders, so I mostly shoot in 30p.

Just got a response in Cineform forum that hdlink conforms the 60-24p, cant wait to see how that looks compared to the 60-30

As I said earlier, if you post it correctly, it will look the same - just slower.

If I understand the question - shooting at 60p, you can slow the footage down by 50 percent in a 30p project and 60 percent in a 24p project. Both will give you the same "smoothness" but a 24p project will give you slower slow-mo.

(I think I got those percentages right. 60p = .5 in 30p, .4 in 24p)

got it. i think i was psyching myself out, because of the way 30 and 24 look so different. and so mentally i was transferring that to the 60conversion without thinking about the math
