I have made a video wall with Vegasaur. All 9 clips are in 1080. Then I use Vegas Smart Zoom as video output effect to zoom in at an individual clip (and then out again). The 1080 rendered video do not show the inzoomed clip at full resolution, it is digital zoom.
Is there anyway in Vegas Pro (or another program) to get same resolution for individual clips when zooming in as descibed above?
Example from Youtube (from 2´16): 
That video is quite a production! :) I suspect multiple clips/renders were used.
While I am not sure exactly what you are asking, I can only say that the initial, original resolution of a video recording is the maximum quality to have, all zoom-ins in the editor will be digital and will degrade the quality. So, to have as much room as possible, go with as high resolution as your camera and computer can handle.
I can't help you with the technical aspect of your question but do have to say - wow - what an achievement and well worth the many, many hours you must have put into it.
I think the linked YouTube video is not the one made by Mats, it's just an example he found.
Add a new empty track, make all tracks be this empty track's child tracks and this empty track will become parent track;
Turn your all tracks' composite modes to 3D source alpha including the parent track's parent composite mode;
Use parent track's track motion to zoom in.
This is often called "3D camera motion" which all ather NLEs don't posses except VEGAS Pro.
But VGEAS's track motion is indirect, you can't control it in preview window. Therefore, it's difficult to adjust the motion.
Track Motion zooms in at Project Resolution. If you want to retain the full resolution of the source you need to use PAN/CROP. It zooms in at source resolution.
After Effects does this kind of stuff very well. A little harder in Vegas.
Ha, ha, if that video was created by the musician himself, unlikely he used Vegas. Fwiw, the only screen grabs he's posted are of himself doing audio projects using Pro Logic X on a Mac.
@Mats you're right. Vegas Smart Zoom would be the wrong fx to use because it only zooms. That enlarges the clip beyond its original resolution. You really want to do the opposite. Shrink the original clips in a window and restore them to original size when you want to enlarge them. Pan/crop, track motion, and the picture-in-picture fx all do both shrink and enlarge so you'd just have to refrain from exceeding 1:1 if you don't want to pixelate. If all you want to do is shrink, restore, and move the window about, pip fx would be the easiest to use. But if you want to trim at the same time, pan/crop would be the one. However, what they did in certain parts of that video with perspective in 3D space... Vegas track motion does that trick.
Thank you for all answers. I found an acceptable solution for the moment. The clips where in 4K and not 1080. So I could render in 4K and squeeze a little bit more resolution out of it. I will though test the solutions from both lan-mLMC and Howard-Vigorita.
Stunning Video!!!!
Just upgraded my experimental homebew videowall setup because I was dissatisfied with my approach the 1st time of animating opacity of cells in higher tracks blocking the view. Turns out I over thunk it and flying a cell above the other tracks isn't that hard, is simpler, and looks better. Here's my v2 rendered 30 second demo clip with 720p portrait cells in a 1440x1080 landscape wall using mostly pip FX and a little track motion for some 3D action:
Also tried upping the res on the cells to 1080p to see if it helped. Sure slowed things down but judge the difference for yourself .
The 2 versions of the project and 2 mp4s I used for the cells are on a google drive here.
It´s looks nice Howard-Vigorita.
My wish was to zoom in at the video wall as a whole not just one clip at the time. Therefore I used "Video Output Effect".
@Mats Do you want this: ? Zoom in but video is still clear.
Use Veasaur video wall's track motion to make video wall. And :
Add a new empty track, make all tracks be this empty track's child tracks and this empty track will become parent track;
Turn your all tracks' composite modes to 3D source alpha including the parent track's parent composite mode;
Use parent track's track motion to zoom in.
Yes Ian-mLMC! Exactly. I will try that. Thank you for your kind effort.
[Edit:] I have now tried it and it works. The preview is very laggy. I did proxy files of the 4K clips but maybe these are not used in this situation, I don´t know.

You should use preview or draft then VEGAS will use proxy files.

Yes I do. It´s still laggy.

Laggy is normal. That's Vegas's performance in complicated project.
