>>10664052They have some kind of secret sauce for detecting your video's compressibility - I imagine they probably run a quick set of inverse kernel resizes
like an "undo" for e.g. bicubic, bilinear, Lanczos resize on a few frames before they decide what kind of bitrate it gets.
Unless you use something fancy like SuperRes or XBR they might decide it's "bloated" and bump the bitrate down anyways.
x264 command line if you want it

or you can just grab StaxRip v2.8.0 - out of the box, it is set up to do a lot of stupid and unnecessary shit like demuxing all of your audio streams, but it's very convenient once set up
