This is both the beauty and the bane of Vegas, namely the interaction between:
1. Selected events
2. Loop region
3. Selected tracks
I have never found this interaction satisfactory, because I can never predict what the heck is going to happen. I have written various scripts to help me edit the way I want (thank goodness for scripts) in order to get around these interactions.
In your case, you've got an interesting problem. If you define a loop region and don't select any events, and then press Ctrl-X to cut, then you cut out every event on every track within the loop region. If any events are selected, then only those events are cut, and only the portions within the loop region. The selection of the track header doesn't make any difference when doing a cut.
But wait, now for the really amazing part. This is where things really get confusing. Make sure no events are selected (click on a blank area on any track), and then make sure no track headers are selected (Ctrl-click to deselect). Now, double click your loop region to make it active. Press Ctrl-X. The events get cut across all tracks just like before. Good. Press Ctrl-Z to undo. Press the delete key. Same as Ctrl-X. Good. Now press Ctrl-Z to undo. Select any single track header, press Ctrl-X. Same thing again. Good.
So much for the setup; now for the finish.
Press the delete key.
Huh? The whole track disappears. Yes, Ctrl-X sometimes does the same thing as delete, and sometimes it doesn't.
Just for fun, press Ctrl-Z to undo the delete. Notice something different? That's right, there is another track selected -- so undo doesn't actually get you back to where you were.
I just tested this on 5.0d and on 6.0a. No difference.
I'm asking because i am so stuck between Avid and Vegas. I love Avid for cutting/handling of media, and i love Vegas for its features.
In Avid, you would simply mark your in and out points on the edit time line. Then select the tracks you want and simply copy, paste, cut, (also lift in avid)
And the result is that it only cuts the clips on the selected tracks.
And if you paste... it simply drops them into the selected tracks.
I see no easy way in Vegas to do this.
I always have to do the left to right click workflow to select the clips i want within the region.
Is there no similar work flow to avids?
I would like to mark my in and out region (aka loop region) THEN select the tracks... and then simply cut copy paste only the clips from the selected tracks. This seems basic to me and it should be in the editing work flow.
Right now i just go through and shift select from left to right etc on the tracks i want.. but that can get tricky... sometimes you cant tell whats selected and whats not etc. Plus its just too many steps for something that could be done much easier with the avid steps i listed above. Its so fast in avid because it can be done all on the keyboard as well as mouse. Vegas does not seem to have a similar capability.
I'm not trying to come down on vegas, its just one of the things that i've noticed.
The other thing i've notice is that Groups are not respected in the Cut/copy/paste features...
If i select a video clip that has a grouped audio clip... (That is to say.. if i select JUST the video clip) and do copy... The copy doesnt respect the grouped relationship and only copies the video clip.
Is there a copy/paste/cut feature that respects groups?
It appears that it costs $99. Really this feature should be inside the program by default. I hope Sony doesnt shy away from it now that there is an addon being sold by a third party.
