Please help with syncing av from diferent sources

[Peter82kr]

I maded synchro with audacity witch change speed effect & synced manually during muxing with mkvtoolnix. Its not perfectly synced but watchable. I stay with this method because gives me best results.

I synced adio from movie with 25 fps with movie 23,976 fps.

Thanks for reply Selur.

P.S.streching with audacity gives bad effects so i think streching in hybrid makes same problems like another synchro on beginning movie and another on ending.
Next time i check speed changing in hybrid.Thanks for reply.

Edit:
Weird but i can achieve same effects on another file ,and speed change in audacity gives same effect like speed change in hybrid.I mean unstable synchro

Edit2:
Do i can chanche speed in filtering using passtrough option?

Edit3:
I used option filtering change speed but a/v synchro is not stable. Changing audio or video fps gives same effects unstable synchro.
