  • Effects on only one part of a video?

    Posted by Mark Young on October 18, 2008 at 5:01 am

    Does anyone know how I can add effects to only a certain part of a video? I keep looking around but I can’t find anything that only limits an effect to a certain part of the video.

    thanks to anyone who can answer.

    Try adding your effects to an adjustment layer and then drawing a mask onto the adjustment layer. The effects will only show through on the masked part of the adjustment layer. You can animate the mask position to change the region of influence.

    Adjustment layers affect all layers below them. If you only want it to affect one of your layers, precompose the adjustment layer and the layer you want to affect.

    If any of this isn’t clear, let me know.
