Perhaps this is obvious for many of you guys, but I've just discovered editing scenario where the "Fit to fill" function of the new Trimmer can be very useful; here it is:

Suppose you have your events already cut (roughly) and aligned on the track. Now, you would like to change the in and / or out point(s), but maintain the exact position in timeline the clip is occupying... Here is the easy way: double-click the event on your timeline (it will put the looping blue bar above it), and from the right-click menu choose "Open in Trimmer". The clip will appear in the trimmer at its entirely, but with selection range of exactly the same length as it occupies on the timeline... Notice that the "Fit to Fill" button is active!

Now, using the Trimmer preview, just drag the selection loop bar left or right (without changing its length), and you can fine-tune the new start / end points of the clip content to replace those on the timeline (where you originally cut/trimmed the clip). With the "Allow to overwrite" option active, press the "Fit to Fill" button - and voila! - your event content has changed as desired, without moving its position on the timeline!

Of course, it's also possible to change the selected time duration in the trimmer - the "Fit to Fill" will still be active, but clicking it now will stretch the event in the timeline slot, causing it to play faster or slower accordingly, but still preserving your original cut points.

My problem with how all this works in Vegas is the reliance on the Loop Region thingy. I feel we need something far more robust i.e. hard in and out points, not markers, not some kludge used simply because the real thing would be hard to code, we need new, unique properties that's attached to the clip. When I set an In or Out point it MUST remain until I take a conscious action to remove it or move it.

Bob.

I absolutely agree Bob - dragging the Loop selection is just too coarse, and doesn't save the in/out edit points permanently.

But with things being as they currently are, I find the technique described above perhaps the only really useful application of the "Fit to Fill" functionality. The in/out points are those of the cuts already in timeline, and this method can guarantee they won't be moved.
