I often need to extend the very final or very beginning frame of a clip. This is currently quite fiddly to do in the Camtasia UI (I'm using Camtasia 8.1), for a couple of reasons:
1. In order to extend the frame, you first have to position the playhead at exactly the right position. Even with timeline snapping, it's very easy to get the playhead positioned slightly out, and find you've extended a frame a fraction of a second away from the end of the clip instead.
2. Extending the frame always moves subsequent clips on the same track further back in time. I almost never want this, and so end up either having to move them back again, or temporarily putting the clip I'm about to extend in its own track just to extend the frame.
3. When you extend the frame, you get the textbox popping up asking how long you want to extend it for. Again, I almost never want that - because I almost always need to judge the time by matching to other clips, rather than by specifying a time in seconds.
It seems to me that these three issues between them make extending an end frame quite a chore - a lot harder than it should be.
Any chance of addressing these issues? There are probably a few ways to do that, but I'd suggest: Fix issue (1) with two extra context menu options on each visual clip to 'extend first frame' and 'extend last frame' - these should not depend on positioning the playhead. And fix issues (2) and (3) with Camtasia-wide options to switch off moving clips and displaying timing textbox when extending frames.
(Or are there any easier options already in Camtasia that I'm not aware of?)
