I figured it out:
Two Point Controllers: Point A (x,y) and Point B (x,y)
One Slider Control from 0-100
Camera null with separate dimensions.
On x position:
var ax = effect(“Point A”)(“Point”)[0]
var bx = effect(“Point B”)(“Point”)[0]ax-((ax-bx)*effect(“Slider Control”)(“Slider”)/100)
On y position:
var ay = effect(“Point A”)(“Point”)[1]
var by = effect(“Point B”)(“Point”)[1]
ay-((ay-by)*effect(“Slider Control”)(“Slider”)/100)Keyframing slider from 0-100 tweens the camera null from Point A to Point B, even if Point A and Point B move also.

I think I got it to work, but as you warned in your article, it’s just way too slow to do it using the frame by frame integrator. I’m just going to take the camera’s speed value and convert it to keyframes, and use the linear integrator on that. The camera velocity doesn’t jump around so much that I can run a smoother to reduce the number of keyframes if I wanted, and the wiggle doesn’t have to be 100% accurate, that this is a good enough solution.
Thanks!
Next question: is there a way to get an object’s rotation “velocity”? I wanted to link the camera’s Z rotation to the velocity of its Y rotation, in order to simulate a banking/head tilt when the camera turns its head. I’d need it to rotate left or right depending on which way the camera is turning, obviously.

I just wanted to reply to this and thank Adam for his suggestion. My renders are flicker free and rendering even faster than the default setting.

Cinema 4D uses the CPU for rendering, not the GPU. A faster GPU would help in the viewport when using “enhanced Open GL,” but it wouldn’t lead to faster render times.

if the person doesn’t need to be moving other than passing the camera you can find silhouettes here:

Make one ambient light to lighten the entire scene to normal brightness, and then make another light that will add extra light to just the part you want.

Thanks! When I do the log to linear conversion the first time around, should I have that as an adjustment layer and do my compositing under that, or do I just apply it to the source footage and do the effects on top of it?

I just encountered this problem myself and the easiest solution I could think of, quicker than out points, was to mark in and outs of the audio file and make a subclip. Then you can multiclip that subclip and the video via in-points and it all lines up.

All that says about importing and using .swfs in AfterEffects is that it is supported, it does not supported scripted and interactive animation (which my files do not have), and can be rendered continuously rasterized.
It doesn’t have any other limitations and doesn’t say anything about why AE would be able to render partway through and then freeze (beachball) before it can finish. It’s not on a specific frame either, it feels like it’s running out of available juice (RAM, I would assume, but I’d never had a crash like this with no error).
Also it seems be based on how many different frames of the swf it’s rendering. A one frame swf frozen and used as a vector still in AE will not crash even if the comp is 20 minutes long, but a 30 second swf file on a 30 second comp will crash.

I am not using multiprocessing.
