Or don't see a need because you know the points :), AFAICT most human 
editors work that way.

Brings another question- if you want to select 15 seconds and no additional 
frames starting at 00:00:03.0 do you give the out point as 00:00:18.0 or 
:17.999 or :17.29 (for a frame count, not a fraction of a second)? I suspect 
.999 will do the job, but it's cumbersome and not as simple to calculate. (I 
prefer frame numbers, myself.)

Later,
