[HELP] What noise is that?

[Selur]

I wouldn't add the frame interpolation, but if you need that frame rate use it.

But why if select FFV1 always have file with PAR 3:2 also if select 8:9 or other format??

Hybrid reads the PAR using MediaInfo if the there is no 'Input PAR', Hybrid assume 1:1.
If you know your input PAR (= pixel aspect ratio) isn't detected properly, you need to let Hybrid know the correct value for it to work properly.
3:2 usually is a DAR not a PAR.
Can't produce the effect that FFV1 always comes out with a 3:2 PAR, here at all:
