[Kdenlive-devel] composite changes

[Dan Dennedy]

I checked in some new features today to the Composite transition. A few notes:

- fetch latest MLT from svn - the kdenlive change triggers a segfault
when a property is empty string.

- Alpha Channel Operation determines what happens when video in both
tracks have an alpha channel. So, don't expect much unless you have
that.

- The Luma options are nice for picture-in-picture. However, it will
not appear to work until you keyframe changes in opacity. IOW, the
opacity level determines the progress through the luma wipe. For
example, imagine you fade in and out a picture-in-picture: 0 -> 100%
at the beginning of the composite, hold for a while, then 100% -> 0 at
the end. Now, choose a luma file, and instead of fade, it "wipes."
Therefore, do you think there should be a hint after the label "Luma
Image File" that reads "(tracks opacity)"?
