So you get a ringing free good quality resize. The idea is to resize in bicubic (catmull-rom) for high contrast features, and spline64 for the rest. This one is not really mine, it's only my take on the one found in this post. Not the best of these 3 of course, but anyways is there. Some other options and insights in the script, check them out. Ratio Resize is a simple preview purpose resizer based only on single figures, like PAR, DAR, % of original size, and 2 interesting modes for snapping a source width (or height) to a certain value with proportional overall scaling. OK, I already know the Pixel Aspect Ratio of my source, how can I preview it quickly? with RatoResize() of course : P Yes, you can easily call it the best resizer out there. Automatically detects colorspace (RGB or YV12) (You could skip resizing and use it only for matrix change in 32bit as well) It automatically changes matrix when switching from SD to HD or viceversa. It resizes in 32 bit, with lsb_in/lsb_out options. It revolves around the resizing functions in the Dither Tools but made as easy as a one-liner. Here is a pack containing useful functions for resizing.
