It wont chase unless you specify an inframe value... (unless its 00.00.00:00)
The inframe defines the start point to sync - if timecode is running at a value greater than the movie - it wont play if the inframe is unset (or 0) - unless you "enable SMPTE looping outside movie length'...
Nice idea - but I dont think its currently possible as you describe...
... but it would save a lot of time
Richard - is this possible??
