Masking Problem??
Hi,
I have never had this problem before, but i seem to be having a problem with my masks. It seems to be not masking exactly what i have outlines, but a few mill to the side?
Hopefully the screen shot i took will explain it a bit better, but im doing this for my major assignment, and i have sat for about an hour now trying to figure out where i have gone wrong..
I moved the mask in the screen shot to show what is happening a bit clearer.This is really bugging me. Any help as to what could be causing this would be much appreciated.
Thanks heaps,
JDEdit – The top of the mask is where the problem is easiest to see… Please note that i purposly moved the mask so it does not line up with the actor to highlight the problem…

Hi, I would recommend not tracking on the same layer as the footage, but rather on a solid above the footage. Then set the footage layer’s track matte to ‘alpha matte’.

Hi Jordan, by the way in my first post I said tracking but I meant masking. I guess that’s what I get for responding at 4am 😉

Haha, no worries..
Just wondering, as i want to alpha matte the masked area to a solid layer with fractral noise (teleporting effect) would this still be possible to do? Even after i have already alpha matted the newely created solid to the original raw footageThanks heaps for your replies..

Hi, if I understand it correctly, I think what you would need is
Layer 1. Solid with mask
Layer 2. The footage with effect applied (set to Alpha Matte)Then bring this comp into another comp with a cleanplate of the footage.
As an aside, although it is hard to get used to at first, for more versatility in doing compositing style shots in AE, precompose everything (especially mattes) and keep your project panel very organised.
