Problem with frame rate of RAW 1:1 mkv

[atomico]

good morning to all,

i have a little problem with frame rate of a source RAW 1:1 mkv.

i extract the mkv RAW 1:1 (dvd ntsc JP) with MAKEMKV and i obtain a RAW file with 23,976 fps

but when i load this file into Hybrid in the info tab i see 29,97 CFR

when i start encoding the resulting file mkv have audio not syncronized.
i try the same encoding with Handbrake and the resulting mkv was perfect (also the audio sync)

turn back to Hybrid (because, for me, the encoding are better) and go to FILTERING TAB --> Misc and activate OVERWRITE OUTPUT and setting the correct fps.

at the end of new encoding the mkv is perfect, also the audio sync.

my quest is: it's the right way to have the correct fps of the original RAW 1:1 mkv?

or i have to go to the SPEED CHANGE TAB?

thanks to all
