Well ignoring requests for ffmpeg console output and a section of the master that the provided samples were made from means that less people will even try to help you.
I don'n know how to reach for ffmpeg output console, but here is a section of the master video:
OK, so after converting good, bad and master to ffv1 and getting them start at the same frame, testing is easy = make test encode from "new" master, then a script can almost instantly make appear 4 stacked .pngs of any frame I want. They are all crap in different ways, depending on what frame is chosen but I guess the aim it just to get a look more like the good than bad. I am using newer ffmpeg/libx264 than you, and of course this test is not perfect eg. I convert to .png (with flags) which may look better/worse than whatever player you use. Also as I cut to match frames the starting point is different - but given all that the thing that gets me closer to your good sample is simply adding -tune psnr ..... -c:v libx264 -b:v 2048k -maxrate 2048k -bufsize 5000k -tune psnr -preset veryslow ...... Maybe other options will get closer - you would really have to post a screen/player shot of what you consider "bad", one with the clock on screen so I can easily find the frame and compare.
