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.Letty commented
Any thoughts on RedGiant's Instant4K vs. PPro's basic upscale? I think the 4K is a pinch better because you can adjust a few settings, but, it's a plugin and not processed by the gpu, so it adds time to an export. It's always something with this software. Any thoughts would be highly appreciated. I'm wondering if PPro is better, but there doesn't seem to be any tests or data on the issue other than 'salesman' pitches online. I wish there was a 3rd party test on those 2.
