I would like the effect of the alpha track matte - a transparent mask - but it seems to only work on text and shapes that are directly drawn in After Effects. Is there a way to get this to work with PNGs? I would like to use a transparent mask on moving PNGs.
Thanks in advance!
Alpha track maps work on any layer below them. The layer above needs some kind of transparency. Put a solid above a PNG, draw a closed mask path. Set the layer below to use the layer above as an alpha track matte and voilà transparency.
Ahhhh thank you soo much! You are a lifesaver!
Glad I could help. BTW, the first line should have read Alpha Track Matte's .... got to love voice to text....
