If someone has seen films like "dog soldiers" or "28 days later" you'll see a very jerky motion in short cuts of the evil beasts. The secret isn't just to exclude frames, is it? I would be very happy if someone could help me with this effect to get some really creepy results.

Are you talking about shake like that in Saving Private Ryan?

If I remmeber correctly, it is a exsposure trick the happens in camera. The shutter only exposes half the image per frame then exsposes the other half on the next frame. Left and right is the orientation I think. You could try this with a track matte or a mask. Other than that, there got to be a plugin out there that can simulate the effect.

Attach a small motor with a counterweight to your camera lens if you want earthquake/Star Trek/Top Gun shaky cam.


And removing specific frames is a great way to speed up specific motion.

Remember the blurry faces effect pioneered by "Jacob's Ladder" (and then copied by every horror film since?). That was a combination of slow shutter for blur and frame removal for speed.

Remember "Missionary Man" from Eurthymics? That was a cool use of frame removal. I was listening to Cameron's commentary on T2 and they removed frames in a scene to give it more impact (literally!).

You could
Comp 1) Apply ReelSmart Motion Blur with a scale of 1.0
Comp 2) Drop Comp 1 say 4 times in it and offset each instance with transparency so they are visually equally weighted (100% opacity bottom layer, 50%, 33%, 25% top layer)

Comp 3) Drop Comp2 into Comp3 and posterize time in the manner of your choice
There are variance on that theme of course

Once sapphire is available for AE you'll be able to do this with a click.
Right now you'll need to add mondo keyframes of position changes with motion blur turned on. You can copt/paiste some of em to save time but you'll need to go in and change some keyframes so it doesn't look looped.

If all you want it camera shake, the wiggler is much easier than hand-keyframing, and the wiggle() expression is also quite good (I rarely even bother with the wiggler any more, thanks to this expression).
