That's a very big step.

Why is that?

That's fine. At present piave does not allow empty frames, i.e. frames where 
no information and all other inconsistencies. PIAVE fixes all such 
errors/inconsistencies, but this is actually a 'feature' that can be switched 
off.

MovieDVperfect displays a test screen. This way you'll notice directly if you 
have such errors/inconsistencies in your timeline.  It's trivial to implement 
a command to let the user choose what happens with empty frames (black, 
white, testscreen, etc.)

What do you mean with overlaying? One problem I see is, when you have two 
clips on top of each other in the timeline and you have not defined an 
operation between the two. In this case piave uses a NullOp which will just 
pass through the fame from he first (top) track. Is this what you are 
referring to?
