I'm using After Effects CC 2017. I've imported a PNG image with transparency, then I added a simple CC Light Wipe effect:

enter image description here

The problem is that the range of the lights produced by this effect are limited to the image size, so it produces an annonying thingy. Is there a way to resize the canvas of the layer of the image or another way to solve this (avoiding the need to resize the image canvas using external programs like Photoshop)?.

I really tried to find out the answer researching in Google before asking here but I only found questions about resizing the entire compossition in the compossition settings...

    May I suggest that you spend a few hours going through some introductory video tutorials: aefreemart.com/…

Add an adjustment layer on top (right-click in empty area of the layer names. Go to New menu) Apply the effect to that.


And because there's always two ways of doing anything in After Effects:

  • precompose the layer to which you want to apply the effect.

  • In the pre-compose dialogue choose "leave all attributes…".

  • Resize the new composition to the size you need.

  • Then in the original composition apply the effect to the pre-comp.
