    Dear Creative Cow,

    I am working on a presentation for the Future Lions competetion deadline this monday

    I have been working all night trying to fix an issue masking a image. I have placed a mask on the screen and animated so when the buss drives by it disapears. But when a place effects on the layer it doesn’t include it in the mask? See the OldTV effect and color difference on the buss.

    Can Anyone tell me what seems to be the problem?

    Hope and regards
    Peter Ammentorp Lund

    I’m a little confused by the set up here – I’m assuming the top layer (hej.mov) is the man/screen footage and the second is the traffic, in which case your mask is on the footage layer which I think is what’s causing the problem.

    For future reference it would have been better duplicate the traffic layer and masked in the bus on top or even masked out the screen on the traffic layer putting the screen footage behind. Either way would have kept the screen footage mask free which would have made things easier (Not to mention the bus version would probably be easier to mask!).

    Still, if you select the top layer and pre-compose it (Layer>Pre-compose) leaving all attributes where they are, you’ll make a new ‘sub composition’ where the screen-footage should look normal. Add the TV effects to the footage inside this new comp, and they should be better contained by the mask. (I think – I haven’t actually managed to replicate your problem here – just decided this should fix it 😀 )

    Paul is right that it would be better to have a second instance of your traffic over the top of your tv screen layer. It’s not too late to do it his way either.
    Duplicate your traffic layer and move it on top of your comp.
    Select the mask that’s on the tv screen. Copy it. (I’m not in front of my AE machine at the moment, but I think you can just use cmd+c on the mac, ctrl+c on the pc)
    Paste it on your top traffic layer.
    If all your keyframes and everything line up properly, then delete the mask from the screen layer and all should be well.
