Multiple resize effects

I have some footage that was shot vertically, that is, with a 16x9 camera tilted at 90 degrees. So when looking at footage, so I don't have to tilt my head, I applied a transform as a source effect (master clip effect) to rotate it, but since it's still in the 16x9 footage, I have to reduce the size to about 53 percent to see the full width of the shot in the height of the window. Now, if I use this footage in a sequence and enlarge it using the normal (Motion) scale parameter (to something over 100) and not the transform effect, am I blowing up something that was re-rastered smaller, or will the effects cancel each other out (in terms of quality degradation) until I cumulatively surpass the original size?

As long as Transform is being used on the clip and not on an Adjustment Layer it shouldn't be rasterized. You should be able to scale up without affecting quality up to 100%. I haven't specifically tested this with a Transform effect on the Master Clip Effects, but I imagine it would still hold true.  

(And yes, mixing it with regular scale should also be fine.)

Great, thanks. So if I reduced the size in the master clip effect to 50%, then increased the regular scale to 200%, my size should be around the original 100% with no loss of quality, right?

Yep. That's correct. I just tested it on my side as well and I can't detect any difference in quality.
