Understanding Video Bus Tracks (Would appreciate input!)

So, it is my understanding (please correct me) that in the audio world, Bus Tracks are used to minimize stress on your performance. So for instance, if wanted a reverb, I would dedicate a bus track with the reverb - patch the intended audio event to that particular bus track. This way, the BUS track would use the CPU thread ONLY for the reverb and nothing else, as oppposed to throwing effects on a regular track, which rides the processor beyond the grave since it technically will process that effect infinitely using everything you've got.

Once again - please correct me.

VIDEO BUS Tracks appears to be a global method of adding effects, in other words, whatever I do there, effects every single video track I have available. If my above understanding is correct on BUS Tracks and in theory, Video Bus are the same, is it possible to assign my video bus track to a specific video track?

The video busses are called "Parent Tracks" in Vegas Pro and a Parent Track (aka Video Bus) will then affect all the Child Tracks associated with that Parent Track.

Thank you for responding, Marco.

Can the association be done manually? In other words, if I have 4 video tracks and only want 2 effected by it, can I associate only said 2 to that bus?

Sure, on the track header of each video track there are icons available (you may need to make them visible via the hamburger menu) which let you make tracks to be child tracks of the track above (if there are at least two video tracks).

The only requirement is (which is different from audio busses), all Child Tracks of one Parent/Child composition (no matter how many they are) must be directly below the corresponding Parent Track. Then you could have as many Parent/Child compositions as you like.

Also this can be further nested, so the Child Track of a Parent Track can have further Child Tracks of which them it would act as Parent.

This explains a lot!

I'll try to test this and see how it can suit my workflow. At the moment, I would guess that this is deal for multiple camera scenarios for something steady like an interview.

What's further to be done then is to apply FX which should affect all Child Tracks as Track FX in the Parent Track and set the FX after Composite in the FX window. So you could further adjust which FX would affect the Parent Track only and which would affect the whole Parent/Child composition.
In some cases it is useful to use an empty Parent Track which does nothing else but controlling the Child Tracks.
