So I'd like to use another track to record mouse movements.
Ideally, i'd like to have the track be about 16x16 pixels (or whatever
the
mouse size is), and be able to specify that it a) overlays the other
track
[this I'm pretty sure I can do, after having read the QT tutorial],
and b)
specify it's position - that is, move it about - not have it fixed at
0,0.
Sounds like you need a sprite track and a modifier track that sets the
position of the spite (through the matrix).
If not - is using a clip region effective? (e.g: a full size secondary
track, just for a mouse cursor - where almost the entire track is
blank/empty/white (whatever is appropriate), with a clip region around
the
mouse area? If I do this - will QT be smart about what is encodes?
will
is record only the small area defined by the clip region? or will it
still
encode an entire frame?
It will encode the entire frame but if do any compresssion (like high
quality JPEG) the data size of the white part should be negligible.
