Problem with frame rate of RAW 1:1 mkv

[atomico]

good morning Selur,

2 news:
-try with "overwrite output" (into actual OSX) and seems working well.

- try installing (on VIRTUAL MACHINE) ubuntu desktop last version and download hybrid for linux. in this case i find in FILTERING -> Misc -> Overwrite Input   what you suggest me before
  try to encoding and i obtain the correct mkv

one notice, when i load the MKV RAW 1:1 hybrid read always 29fps

best regard and thanks
