Faux High Speed Film
I don’t know what the name of this effect is. I don’t think it’s bullet time. You know those cliche shots where they use high speed film, say 120fps, and the camera quickly moves to a specific location of the subject, then once it’s locked in on that location it slows way down so you can appreciate the detail it wants to you show you? Then the camera quickly moves to another location and slows down again? Think of a Gillette Razor commercial or something. Well, I’m looking for the best way to recreate that using only CG frames. since my 3D app doesn’t allow me to choose a “film speed” for my camera, I guess I would just have to take my original animation, select all of the keys, then scale it out to 4x it’s original timing. So if a turn table originally took 30 frames to rotate 360 degrees, it now takes 120 frames. Then I would drop my painfully slow animation into editorial (in my case Premiere) and scale the timing back to normal.
My question is this: How do I put the speed of my clip on an bezier envelope, so I can slow down and speed up the clip in a fluid manor?
Thanks,

Read about the Time Remapping effect. Also make sure Frame Blending is checked.

I’ll do that. Thanks, Mike.

If it is CG, then create it at the proper speed for each part. Then you don’t have to ruin good animation with frame blending.

Point taken, but if the client wants the camera movement slowed down or sped up a tad, I’d much rather have the option of making that change quickly in post than having to re-render that stuff out of 3D again. Besides, if you slow down your 3D by a factor of four, then speed it up by a factor of 4 in post, the timing should look normal again. The only difference being that you would now have the option of slowing it down at the desired points without suffering frame loss. That said, I haven’t seen the results of frame blending, so depending on what it does I may be inclined to agree with you.

You may want to look at reVisionFX (dot com) Twixtor, as it goes way beyond frame blending. It can take some effort to get clean results, but it’s very impressive. I use it in Combustion; not sure if any functionality is compromised in Premiere, but I think there is a demo version.
