@rgr Hi, have a look at Parent-Child, you can move the Parent track which will mov all the child tracks connected, or you can add an adjustment track, Parent-child the tracks you want to that adjustment track & add whatever effects you want &/or move/zoom that parent adjustment track which will move all the child tracks..

Thanks, works!

But there is a new problem -- Parent Track Motion starts with 1080x1080 image parameters and only such a square can be animated (child tracks contain 1920x1080 video). If I manually change it to 1920x1080, the image obviously expands.

The above is a bug in my Vegas -- the width in the Motion field is taken from the *height* of the project. It's time to upgrade.

One more question -- how do I temporarily disable Parent Motion? Mute disables all Child tracks at once. The Level slider has no effect either.

Key Frames.

? How to temporarily disable them without removing them?

@rgr - On the Parent Track, Delete KF, and then UNDO? I really want to know what it is your final objective is.

@rgr said "...I would like to apply it to the track (and all other tracks)."

Try nesting.

If you want to do the same thing to all clips why not just set it up on one, copy, then select the rest and past attributes?

Yes, that's what I thought of. I thought there was a way to disable the effects of the Parent track itself.

Because there is no continuity between the clips on the remaining tracks, they are fragmented. And the effects are supposed to pass through everyone.

I wish I had your ScreenGrab to advise you further.

And the effects are supposed to pass through everyone.

I've looked through your recent posts and comments and couldn't find a mention of which version of Vegas Pro that you are using. But if you have Vegas Pro 20 or 21, you can add in an adjustment track and any FX added to that adjustment track affect all tracks below it. In Vegas Pro 21, there is also now an adjustment event that is an empty event on a track where any FX added to that adjustment event affects any tracks below it for the length that the adjustment event on the timeline.

Because there is no continuity between the clips on the remaining tracks, they are fragmented.

Could you please explain what you mean by 'fragmented' - maybe 'separated'. It is common in video editing (regardless of NLE) to have video events spread over many tracks for any number of reasons.

There is no longer a problem with zooming all Child tracks, everything works as it should.
Now I just want to be able to disable effects introduced by the Parent track so that they don't work on Child track. Of course, the Child tracks themselves should be visible.
For now I see that the only way is to remove the keyframes. Or move the Child tracks over Parent.
PS. Vegas 19.

@rgr - I don’t understand.

@rgr Hi, how's about this,

1. Add your tracks to one Parent track, that Parent track has nothing on it but is keyframed to do the zooming, you could also/or use an Adjustment track
2. Click the top one of your Child tracks, press & hold the Shift key, then click on the last/bottom Child track, this will select all Child tracks,
3. Click Make compositing Parent on the top Child track, this will release those Child tracks from the Parent.
4. Make the adjustments you want to the Child tracks, I'm assuming that's why you want to disable them from the Parent,
5. When finished adjusting the Child tracks, Click the top one of your Child tracks, press & hold the Shift key, then click on the last/bottom Child track,
6. Click Make compositing Child on the top Child track, this will add those selected Child tracks back to the Parent with all Child tracks in the order as they should be, & the Parent zooming keyframes will be intact as you left them.

Another simple way to do it is via an fx applied to the video output bus (fx button above the Preview pane). Try fx such as Pip (quickest), Smart-Zoom (deprecated but fairly quick), or Upscale (resource intensive AI). If you can get it to work at the event-level however, with an adjustment-event (still buggy), I think pan/crop might be the quickest and generally gives better quality than Pip or Track Motion.
