Activity Forums Adobe After Effects How to create this effect

  • How to create this effect

    Posted by Matjusm on November 25, 2007 at 10:17 am

    I want to create that effect that is used so much during action scenes in television shows these days- where it seems like the footage is captured at a low framerate or something like that (as in everything moves quite fast/there seem to be gaps in the movement of things between frames). I read somewhere that this is an in camera effect done by messing with the shutter speed but since I’m going to be working with a Sony Handycam, such an option is out of the question. Does anybody know how to, or if it is even possible at all, to create this in Adobe After Effects?
    I hope I described what I’m trying to achieve clearly enough.

    I believe what you are talking about is where its a 24p frame rate but a high shutter speed. Like the fight scenes in Gladiator. I dont know about doing it in post. What about changing the FPS in the composition to 15?

    It seems you are describing a modified strobing effect.

    If so, then this is best done with a NLE. It is real simple to do this with a video editing software and not something as complex as AE. In fact, I have never tried to use AE to achieve this effect since I can use my video editors strobe effect to do this with one simple adjustment.

    Ok, how would I achieve this in Adobe Premiere or Sony Vegas?

    Sorry,… I don’t use either Vegas or AP…

    I use Avid Liquid…

    But… I am sure there is a similar filter.

    In Avid Liquid it is Strobe option called Linear Timewarp.

    Basically, what you are doing is simply removing a frame every x frames and increasing the appearance of the a faster frame.

    “The DV Rebel’s Guide” by Stu Maschwitz describes how to do this “strobing” effect in-camera. If your SteadyCam allows you to adjust shutter speed, an Excel spreadsheet included on the DVD that comes with the book helps you calculate the proper shutter speed depending on your frame rate.

    I’ve read this book almost cover to cover and highly recommend it for anyone shooting low-budget films on DV cameras. It’s a great guide for the entire pre- through post-production process. Stu’s blog is here (https://prolost.blogspot.com/) if you want to learn more.
