Currently, Premiere uses the Lanczos method for intrinsic scale and rotation. Lanczos is an exceptionally high-quality interpolation method which generally yields better results than bicubic, bilinear or nearest neighbor. From reading the forum post, it seems that up-scaling is the real issue here. I suggest looking at the Detail-Preserving Upscale effect in After Effects. It does a really good job and gives you some parameters to tweak to fit your specific content.

Game trailer editor here! I work on pixel game trailers all the time where a bit of nearest neighbor on motion-scaled shots would save me hours of my life! Please add this to the next version of Premiere, Adobe. Pretty please!Mjoshua cauller supported this idea ·
