What kernel does After Effects use for resizing and what is the algorithm behind it? For example if i have a 1920x1080p composition and i make a 200% zoom, which kernel is used to upscale the picture? And if i do a 120% zoom, or i downscale it to 50/80% of the original resolution? Is the same for Adobe Premiere as well?
details about scaling in the new version of After Effects:
... and in Premiere Pro:
Yeah, that made things clear, but it dosn't says which kind of bicubic, Catmull-Rom spline, Mitchell-Netravali, Hermit and so on. Is it always the same whatever it is upscaling or downscaling? Also, the UV channels (when they are used) are always upscaled/downscaled with the same kernel?
