Coming from an NLE background we are well used to ‘add transitions‘ to a bunch of edits (including ‘match frame/split/add’ edits).
Why? Among many other reasons:
1. To smooth removal of sections (eg umms, coughs, non-speaking sections of iso mics)
2. To smooth transitions between levels of clip gain (eg to compensate for off mic sections )
So it’s definitely a very useful thing to be able to do.
IMO Avid media composer does it best with ‘add transitions in to out’ (in to out = time selection) with a dialogue that offers duration of transition, and position (ends at cut/centred/starts at cut and custom).
