Moving mask

[Leo Souza]

Hi all,
How to create a mving mask for a single clip in arena?

[HerrNieDa]

only with a extra layer if your clip is the first layer...
other ways... if i think about a workaround which is little tricky but should work
1. set an extra screen (bigger comp size) for the clips you want to get masked (3 extra layers for the second screen)
2. set layer position to the second screen for the 3 extra layers
the first extra layer is your clip
second one is your mask
third layer is an effect layer (for positioning), drop fparameter effect on it or similar to position the clip on your main screen
3. you are hopefully not using a/b layers, so set all 3 extra layers to b, the rest to a....

i don't tried this workaround now, maybe you can work without the effect layer and without the second screen but it just squirted out of my head...

other way -
