[MEncoder-users] Convert MTS to MP4: Video and audio out of sync

[Ooe Eoo]

> Using MEncoder about 3 years ago, I tried to convert DVB videos from a PVR 
which uses the MPEG Transport Stream.  Even with -noskip -mc 0 -vf harddup 
and some other tricks, the audio would never be in sync at all.  Usually a 
second out.
So this looks like a bug that has not been fixed for a long time...

The MTS extension file is a high-definition MPEG Transport Stream video 
format used by Sony, Panasonic and other HD camcorders. It is based on the 
MPEG-2 transport stream and supports 720p and 1080i HD video formats. MTS 
files are opened and edited using the software included with Sony and 
Panasonic HD camcorders. Looking for how to open mts files? Checkout
