  • Interpreting footage vs changing frame rate in composition

    Will interpreting a 25fps footage to 18fps achieve same looks as putting your video in a composition and changing the composition setting to 18fps ? I am trying to achieve a super 8 look here. Interpreting footage throws it off sync with the rest of the effects and audio(lucky for me a bit, as I won’t be using the in camera audio.)

    Haha, I chose putting the uninterrupted footage in an 18fps comp. I want that jittery motion as a video recorded at 18fps would have(sort of).
    Thankyou for explaining the theory behind it as well.

    to be picky, dropping a 25fps into a 18fps will be super jerky. There is a difference and smoother motion when using optical frame blending which Ae has from 25fps to 18fps. the first method is aken to using the posterize time effect and is very, very jerky.

    smoother way-
    Choose Layer > Frame Blending > Pixel Motion.

    Thankyou, I rendered out my final footage and the results were satisfying. Pixel blending helped.
