Only working alternative I found for this wast orender in 4k and then re-render in 1080p (resolution I need)

You can also do 'nesting project', put this required large-resolution sequence in separate VEG project. Then put the VEG project on your final project where you can do event pan/crop zoom. By doing this way, you don't have to do 4K prerender.

I would like to know more , I havent tried such thing so, I f there is any guide,info on how to do this, it would be great!

easy, just put the VEG project to the timeline, just like other Media sources.

OH right.. well render times seems to be about the same lenght +/- as 4k render.. interesting

Thanks a lot for info! I'll check if quality is up to par to aht i want/need

4k render time : ~33min for 1min of video

1080p re-render time : 2 mins

-----

Nested project render (720p nested to 1080p render) : ~22mins

Nested project render (4k nested to 1080p render) : ~24min (better but still 1:24 ratio which is terrible!)

Quality of nested one is not up to par!

Nested project render (4k nested to 1080p render)(changed format,codec & quality) : ~24 min & no change in quality!

----

will test later the removal of track motion substituting it for pan crop in the final project...

Update :quality is spot on how i need it, BUt for 30sec clip render time : ~24 min ..idk ..more testing needed

When you set up the scene make sure nothing is in front of Zero in z space. Or minus space in z space. Make things bigger in + z space so your camera pan always stops at zero in z space. The perspective will stay the same = bigger things in the background look the same as smaller things in the foreground = same thing. result everything is in focus if that is what you want.Also set up a square work size 2000 x 2000 square pixel.  Example

Or like this sample  my back ground work space size or project size is say 3000 x 3000 but everything moves x,y  and almost no z spacemotion . the camera moves only + in z space.

Here's one of my nesting project I did a year ago:

The 1st main project was 4K size (max size is 4096x4096), then on the 2nd project I make an event pan/crop zoom to the nested 1st 4K project.

the issus is also Set that when you nest the veg the camera motion canot be brought farward to the new veg file so is rendered at the current parent veg file project settings. so why nest it then? nesting can help with compositing issues but thats about it

1st main project contains the 'book flipping' motion. And due to complexity of the 'composition' of this book flipping, the zooming motion is done in other 'timeline' (2nd project).

Only with Event Pan/Crop - the large resolution is maintained when you zoom in.

Track Pan/Crop cannot do this. (I think it follows the audio volume workflow - where event volume is like event pan/crop - an track level volume is the overall volume)
