I've been battling with Sony Vegas Movie Studio 11 (SVMS11) to have the audio correctly in sync with 3D video shot with the Sony HDR-TD10.
The crux of the problem seems to be that when the TD10 shoots for more than about 20mins, the MTS files in the camera automatically get split into 2GB segments, and when SVMS11 imports these files onto the timeline, it gets the audio sync all wrong. SVMS11 doesn't recognise that the start point of the audio and video don't always coincide and it also sometimes miscalculates the correct length of the video clip AND the audio clip. As a result the audio can be very wrong at times.
I've tried using "Videoredo" to "Quickstream Fix" the MTS file, which does overcome the audio sync problem, but Videoredo doesn't recognise the secondary MVC 3D stream so the output file is only 2D.
Someone on this forum suggested using the Sony PMB program supplied with the camera to join the individual 2GB MTS files. In my case one of the resultant M2TS files is ~8GB in size (~60mins of video). This does seem to solve the audio sync problem when playing in an external M2TS player, however when I try to import this 8GB file into SVMS11, the full length of the video file is not shown on the timeline (perhaps only the first 2GB). Is SVMS11 limited to 2GB files?
I've also tried using another utility (TSMuxer) to intelligently split the 8GB M2TS file into 2GB segments, but this particular app also doesn't recognise the secondary MVC 3D stream so the output file becomes 2D again.
Has anyone found a solution to these issues?
It seems to me that (a) SVMS11 doesn't correctly interpret the audio/video sync in the unusual 3D MTS files, and (b) SVMS11 won't import files larger than 2GB. I'm been trying to find a workflow to preprocess the files to overcome these hurdles, but no luck so far...
This is of course in addition to SVMS11's problem of the incorrect decoding of DD5.1 in the 3D MTS files (introducing clicking sounds in the audio) of which a solution was discussed here:http://www.avsforum.com/avs-vb/showt...6#post20492186
In my case, I couldn't find the installer for SVMS10 so I used Videoredo to strip the audio out of the MTS file and Goldwave to convert the AC3 file into a 2 channel WAV (SVMS11 won't directly import an AC3 audio file). BUT... audio sync is still a problem since SVMS11 seems to be incorrectly detecting the correct duration of the video file. sigh...
