Scaling Pre-Comp losing resolution

I have been working all day on a wide tracking shot that shows a character moving from the sidewalk into a driveway to the front door from the side. I have been stabilizing it by both tracking points, manual rotation, and 2% warp stabilizer as I don't want the clip to crop too much.

Each transform I did in a different composition:

Comp 1: Scaled to 84%, manual rotation for the horizon line;

Comp 2: Single point track on the character (x-axis only);

Comp 3: Rescaling, and manual Y-axis keyframing;

Comp 4: 2% smooth warp stabilization (for the small jitters)

This issue here is that pre-composing the footage scales down the resolution, not just the clip size.

TL;DR

Is there any way to scale down footage in a pre-comp and scale the pre-comp up without loss in resolution?

If anyone can help me with this, I would really appreciate it.

Thanks so much.
