I have only thought at a quite high level on how the interface between 
Kdenlive and piave will work for capture. Here are my questions/thoughts on 
recording.

Will Kdenlive use an existing monitor for capture (for example, the clip 
monitor), or a separate "record" monitor? My thoughts are that we should have 
a separate record monitor, so that we can customize it with record-specific 
functionality.

I think that a separate piave process will be used (Edwin, don't be scared by 
this detail, it is all handled internally in Kdenlive ;-)), so we could tell 
piave very early on what it's task is.

If you have any questions on how to start, then please ask :-) As a hint 
though, take a look at the existing KMMMonitor class. This handles the 
exiting clip monitor and workspace monitor, and would be a good starting 
point for adding another monitor. 

Cheers,
Jason
