[BUG] audio not synchronized after cutting videos

[Selur]

Hybrid by default should use the frame rate of that the source was detected at. (assuming the source if cfr and not vfr)

I see at the bottom of NVEnc->Base, the command line, which contains --fps 25.000, so I understand that the video track is encoded with this framerate

Can't see that anywhere in the debug output.
Encoding call in the debug output states:

and NVEncC also states:

-> no clue where you saw the 25fps, but it doesn't look like it was used anywhere.

If Hybrid would have been 'oiff' with the frame rate, the reencoded output would already be asynchronous.

-> no clue why it isn't working for you
