Best Way To Achieve Slow-Mo

Hey Everyone,

Every search I do for this wields countless tips for HVXs (grrr), but I can't seem to find anything on the A1. I'm looking to shoot an entire commercial slow mo. I've heard that the best way to do this is shoot 60i then just slow down in FCP. Does anyone have any suggestions?
 
High shutterspeed is the key to good slow-mo. Even at 60i anything under 1/120 is too blurry for a clean image.

Shutter Speed

Thanks for all the info. At the beginning of those threads, the person mentioned they shot at 1/120, but no one commented on if that was appropriate or not. Does anyone know at what point strobing becomes an issue?
 
I'd say at 1/180 and above you may notice extra-crispy strobiness...but you might like that.

Gavin, if you're going to do the whole commercial as slow-motion and don't need to intercut with actual 24p material, it's best to just shoot fast shutter 60i HDV, capture and edit 60i HDV, and then downconvert if needed. It should look fine and will save you a lot of hassle over trying to get progressive slowmo from 60i. Field-blended HD 60i slowmo can look pretty darn good, actually.
 
The first ten seconds don't need to be slow-mo, so I thought I could shoot them in 24 or 30, then move on to 60i, going to decide in about 6 hours. I looked at your posts on the other threads, and I'm going to try to follow your import --> CT --> QT workflow. Now that I think about it, I could just shoot regular speed shutter at 60i then ramp it up for the slow mo stuff. Would that work? Thanks for the tip, I'll post some footage in a few days.
 
Elton,

Shot in 60i, mostly at 1/120 because I'm a wuss. So you're saying since I'm not intercutting with any 24p, I should just slow down the 60i? It's currently rendering doing that. I shouldn't convert to DVCPRO720/60P?

Yeah, that's what I'm saying. :) No need to convert to a progressive format if you're just looking for decent slowmo on a regular 29.97 60i timeline.

If you want some of your footage to be normal speed but have a bit of a film-look, just deinterlace that footage in the NLE. Both should intercut fairly well.
 
cool vimeo video.

One thing i don't get, is how to use PP CS3 slow motion effect with the time remaping to get the whole ramping effect ( 300 ).

Using just time remapping, the slow motion is crap. So does one use the slow motion effect ( can't remember the name at the moment ). Slow the footage down to desired slow motion is achieved, and then use maping to speed it up when wanted?
 
Ah, that would have been helpful too. Yeah it is for the Heinz Take Two contest. I think we got decent slo-mo. Elton's suggestions were helpful.
 
We shall see. I think there were 2,000+ entries. You know how these contests go, they normally pick the most home-grown looking stuff. Good practice, regardless. Motivates you to at least get something done.
