Set To Frame Size, Then Nested. Lowered Resolution?

[Clay201b]

I'm hoping y'all can clear something up for me.

I'm working on a project shot in 4K. I plan to output the final videos in 1080p. I created 1080p sequences and dropped my 4K clips into them, then right clicked on each one and chose the option "set to frame size." I planned to take advantage of the 4K footage by scaling them up and, effectively, zooming in on my subjects. I shot the video very wide with this strategy in mind.

Later in the editing process, I needed to stabilize a lot of the footage. Warp Stabilizer will not work on clips which are not the same size as the sequence that contains them. The solution, I read, is to "nest" each clip before using the warp stabilizer. I did so.

Now, I'm at the stage where I increase the scale on the clips. However, when I do this with my nested clips, it appears that they've lost resolution. Furthermore, under "Effect Controls," I see that the nested clips are at 100% (before I increase the scale) while the un-nested clips are at 50%.

Am I going to have to go back and re-do all of this, increasing the scale before I nest and apply warp stabilizer?

I've found some previous questions and answers that deal with a similar - but not precisely the same - problem. Everything I learned from them seemed to be saying that, yes, I'm boinked.

That is correct.

Any scaling is done before nesting:

Nesting will always result in the frame setting to 100%. There is no way around this.
