Twice sizing

I'm trying to make picture in picture effect.
First I make some zoom and sizing on the color page in input sizing or node sizing mode. Then on the edit page I'm trying to put that clip in the left bottom corner of another clip. When I do this I change the the sizing effect which I did on the color page. How can I avoid that?

use a node size for the second pass...

That doesn't work.
I made some zoom and sizing on the color page in node sizing mode. Then I created new serial node. In this node I'd like to move all the shot to left bottom corner. But when I do sizing in this node in node sizing mode I make changes inside the shot. The position of whole shot is not moving.

is it a picture in picture?

does any of this help:?

It doesn't help. Let me explain. I'd like to get the same clip:

But with one addition. I want to apply some zoom, pan and tilt to the shot with the man with guitar.

Use a compound clip. then you can position the compound clip for the PIP & reframe the shot that is inside the compound clip. The User Manual tells all.....

Thank you.

I did it. Everything looks fine in DR. Even during rendering process everything looks great, no errors, no artifacts. But when I open the exported file (youtube max quality preset, data level full) I see some strange artifacts. My mask which was 100% red becomes green with blinking lines around and inside it. I see also strange color spots in different parts of the screen. This happens in that part of the clip where I use compoud clip. Other parts of the clip are fine.

are you rendering from cache? I had some weirdness with compounds clips

My export settings:
QuickTime
H.264
Field rendering - Turned off
3840*2160
29.97
Quality Automatic Best
Key Frames Automatic
Frame reordering - Turned on
Pixel aspect ratio Square
Data Levels Full
Data burn-in Same as project
Use optimized media - Turned off
Use render cached images - Turned off
Enable Flat Pass Off
Disable edit and input sizing - Turned off
Force sizing to highest quality - Turned on
Force debayer to highest quality - Turned on

DNxHD export does the same. I found out that not only the compoud clip generates artifacts. The end of the clip before the compound clip also has artifacts.
My mask - red arrow (255, 0, 0) looks like this after rendering:

1, test an export as dnx HD and see if it is working
2, can you post the specs of the system?

Change the render data levels to "video" and see what happens.

I observe this kind of color change only in optimized media / render cache when I select a low quality format like DNxHR SQ.

In the final render it disappears, if I do not use optimized media / render cache for rendering.

I'm sorry, did you do 1920x1080 (HD) in your test?
