Mix / Blend Movies for Mac

From cf/x:

"Simply the best movie mixing plug available for iMovie."
Mix/blend movies is our best-of-class movie mixing plug-in for iMovie, and represents one of our finest achievement in composition technology. It combines the capabilites of our 'minify', 'multiple movies' and 'simple mask' plug-ins into a single, powerful, and incredibly easy-to-use package, and then improves on them. Mix/blend movies can * position, and re-size the movie to be inserted anywhere on the clip (this means that the you are not limited to a 1:1 blend!) * auto-generate a wide range of blend masks (16 base masks with millions of variants each) * import blend masks created with other applications * create blend masks from any picture * auto-scale the blend mask to fit the blended movie (freeing you of this tedious task) * auto-sync the imported movie to the clip''s length, ensuring that they play exactly the same time (making filming the two clips much easier) * auto-enforce proportions, so you can re-size the imported movie without distoring it
the plug-in comes with 32 professional blend masks created by our art department.
since this plug-in allows you to place and blend movies at arbitrary size with arbitrary blend masks, it allows effects in a single pass that most FCE users will be hard-pressed to achieve in a whole day. finally, as a member of our ''reference class'' series, it also allows real-time preview for all editing.
What should I use it for? Use this plug-in whenever you need to insert a movie into your clip, but need more finesse (e.g. blending, shaping) than our 'multiple movies' or 'minify' plug-ins offer. We recommend that you use it for any non-trivial composition work that doesn't require chroma keying, e.g. * blending two or more movies * knock-out style overlays of two or more movies (e.g. ?burning letteres? with real flames) * documentary-style blends of narrator and story * flashback-style blends * overlay-blends/insertions * side-by-side synched montages * video-wall montages etc.
