if you want to fix individual frames,
yatta is right there, you know (edit:
the only reasonable guide to it that has ever been written - it's hardly user-friendly)
like, you can replace individual frames with like three keystrokes or change field matches with one keystroke, and you have full control over exactly how the ivtc/deinterlacing is done down to individual fields and can visualize it directly, so it's exactly what you want and autogenerates these insane scripts/override files for you
then again you don't seem to be in the habit of taking advice, so I'm kinda wondering why you're even asking questions
