using a mask-clip to combine two sources

[Rene]

Hi,

can I combine two videos (1 and 2) using a videoclip (Black and White) as a mask?

Like this:

Code: Select all

1111111111          2222222222
1111111111          2222222222
1111111111          2222222222

          BBBWWWWBBB
          BBBWWWWBBB
          BBBWWWWBBB

result -->
          1112222111
          1112222111
          1112222111
