video post Q's

[rastermon]

We are compositing our movie in Video Post.. We can take 2 sequences and do a cross fade. No problem. However, if we want to cros-fade 3 sequences - A cross-dissolves to B, and B cross-dissolves to C. Can't do it! It seems that only 2 items can be cross dissolved. I have to say this is STUPID! Even your basic consumer video program comes with these basic tools.
What we have to do is corss-fade A and B, then render those to a movie.. start a noew Video Post project, and bring in our rendered A-B as one movie. Then we can cross-dissolve that to part C. Anyone know how to do this?
Overlaps indicate our cross-dissolve.
