Strobe-like camera effect
For those who have seen Saving Private Ryan and the slew of war movies after that, they began using this camera technique where the footage appeared almost strobelike, like it was skipping every other frame almost. This added extra intensity for when it was used.
Is there anyway to replicate that in After Effects?

The easiest way is to add the effect Posterize Time and set the frame rate to half of the footage or comp frame rate. That’ll grab and hold every other frame.

I know what you’re talking about… it was popular as hell for a while. You should be able to find info on how the effect was done.

apparently it was done with the camera itself, but it’s using a high shutter speed, and a 45 degree shutter angle. Then the film is developed using a technique that desaturates the images.
so, maybe you could simulate the effect, but I think you need a camera capable of a shutter speed of like 10000 to get that no motion blur effect.

The strobe comes comes a low frame per second 24 but a high shutter speed way above smooth blur 1/48th/sec. The same effect can be done with dv by 60i at 1/100th shutter then fps reduced to 24 without adding motion blur or adaptive motion stretching to reduce strobe.
That’s why shooting from 60i to 24p film-look timewarp, you shoot at 1/60 shutter because blur is always best at twice your fps, but if blur is lower, your eye sees strobe from uncharacteristic sharp frame transitions. -
Thanks guys for your awesome knowledge and tips. I know understand the shutter scenario, but here’s my problem:
All my footage is completely digital and does not come from a camera, it comes from After Effects particle work itself and footage of video game scenes. Will it still be possible to achieve the effect with that Posterize Time trick? Or is there a better way?

true strobe is breaking the shutter to fps law. 2:1 24fps at 1/48 24*2=48
We need more information because the posterize time will just make it jumpy like a slideshow. You want strobe. Remove all the blur you can with like something like Twixtor. or try adobe’s trick..
->60-field-per-second video footage can be locked to 24 frames per second (and then field rendered at 60 fields per second) to give a filmlike look. I haven’t tried that but I’m guessing it will create stutter not strobe, but if it looks fine, then use it. That’s probably your only option because you have pure non-blur footage.

This might be work if you use this effect very, very small. Time shuffle in a micro ammount might look similar to strobe.
