[HELP] Audio/video out of sync in output

[Selur]

Is there anything I need to change in Hybrid previously used for NTSC to encode PAL?

NTSC -> PAL is mainly:
a. adjusting the resolution
b. adjusting the frame rate
the only tricky part is the decision on how to adjust the frame rate.
Personally I would either:
a. just change the frame rate and reencode the audio (stretching the audio without reencoding is also possible when using a mkv container)
b. interpolate the missing frames to compensate the higher frame rate and leave the audio as it is.

Another idea: The problem might be with handling the avi container. -> does it help to remux the container to mkv using MKVToolnix before reencoding it?
