Thread: fine-tuning motion of high-speed captured videos

    Default fine-tuning motion of high-speed captured videos

    hello! I'm new to this forum and I also know very little of video editing. My problem is the following: I have recorded facial expressions videos with a high-speed digital camera that captures up to 500 frames per second! Clearly, I have a lot of added information that can't reasonably be viewed in real motion, but I have to approximate real-time motion as much as possible. Above all, what I look for, is that the changement appear smooth and absolutely not jerky. How I can do that?
    Currently, I am doing the following: I import up to 600 static TIFF in adobe after effects, and then I export them to make a movie, setting the speed of the composition at 60 fps or more.
    But the movement is jerky. How can ameliorate this?
    Is it possible with after effects?

    I probably won't be able to answer, but to give people a better understanding of what you're doing, could you explain why you used a high speed camera? Typically this would be for ultra-slow motion playback.

    60fps of uncompressed footage would also playback choppy on an underperfoming system regardless of inputs. Did you compress at all?

    Default high speed motion

    I do use an high-speed camera for the purpose of behavioral study in psychology. I would like to explore how the EXAXT temporal parameters of a naturally displayed facial expression do affect recognition judgments of the same expression. Thus, I will have subjects viewing facial expression movies recorded at 500 fps, which means, videos displaying as much information as possible concerning what happens when producing a facial expression..but I need to speed up the movement a bit, preserving smoothness and information, so that the subjects'sensation while watching the videos would not be too unnatural and confusing with respect to the real world scenes!
    I hope someone will give me some useful advice..
    thanks!

    Have you tried including some motion blur?

    To be perfectly honest, I can't see how using more than 25fps is going to provide much more detail than 500fps to the naked eye. You'll also run into problems playing back on a TV.

    As I say, unless you're going to slow the motion down I don't really see there being an advantage to the ultra high frame rate.
