Pierre,

I have a related question for you, since you seem very knowledgeable about time-remapping.

I have a project in which I want to do the 300 effect: I want to have a clip play in normal looking 24 frames per second, and then, at key moments, slow down to slow motion (it doesn’t have to be extreme, just 2.5 times maybe), then speed back up to normal 24p.

My question is this: How should I shoot this? I’m shooting on a Canon 5D or 7D (I have both). If I shoot it all in 60p, will I be able to remap the 60p footage to look like normal old 24p footage, or will it look weird (choppy or home-video like)? Should I instead shoot it all in 24p and use time re-mapping/Twixtor to slow down the parts I want to be slow? I’m afraid this will result in some artifacting, since it is a fight scene that will have fast motion.

Essentially, I’m afraid that if I shoot it all at 60p, I’ll never be able to get any of it to look like normal 24p motion – if this is the case, I’d rather just shoot my slow motion and normal 24p as separate shots, and avoid the ramp effect.

Please advise if you get a chance!

Thanks,
Keith

Aza,

Did you every resolve this issue? I want to achieve a similar effect for a project I am shooting tomorrow on the 5D – essentially the 300 effect (realtime – normal 24p motion, which I then want to ramp down to slow motion, then back up to normal speed).

My questions is whether its best to shoot the whole thing in 60p, then just speed the parts I want to look normal up, or whether I should shoot at 24p and use Twixtor or time re-mapping to slow down the parts I want to be slow.

The main thing I’m worried about is shooting it all at 60p, and then not being able to get the parts that I want to look like 24p to ever look normal – were you able to get your 60p footage to look normal with time-remapping, because it sounded like you were having problems with Twixtor.

Thanks, Keith
