![]() 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). In my case one of the resultant M2TS files is ~8GB in size (~60mins of video). Someone on this forum suggested using the Sony PMB program supplied with the camera to join the individual 2GB MTS files. 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. As a result the audio can be very wrong at times. 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. 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. 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. ![]() ![]() ![]() I wouldn't delete it incase you need to resync later in your project. Once everything is lined up, then just disable the camcorder audio track on the left or reduce it's volume leaving just the soundboard audio. Your ears and brain will be much faster just listening and sliding. Extraneous crowd noise from the camcorder track will mess with the accuracy of this 3rd automatic method. It is an automatic lineup but your waveforms have to be close to work right. There is a third way too that works but I don't think too accurately in your case. If you expand the resolution of the timeline Use mouse wheel or click on the + in lower right corner, you can also see the waveform match up. Then play it and listen to both together and slide the soundboard clip while playing until the echo or reverb goes away. When you put the soundboard audio recording on the audio track just below your camera audio track, do a rough lineup using the waveform. You can line up the audio two ways, I always used both at the same time because it was easy. Or use time code lock on the cameras and audio recorder. When recording audio separately, always clapboard with a slate and voice countdown as in "title, scene 2, take 5, mark(clap) then count them in. It was pure labor and I billed by the hour. Only one camera had the audio track recorded or the project would have been lost altogether. I once took on a project for a company when my work was slow to sync audio with video for them where some new employees shot multicam with no reference audio, just the video. Once they are close you can look for clues in the speech patters like long moments of silence where the speaker should have his mouth shut. When working blind, to get things roughed in is difficult unless you know what clips are close video / audio. (LTC) Using timecode lock on all cameras ( professional camcorders) I just lined up the TC and all was in sync since every cAmcorder and audio Nagra recorder were locked to same LTC. By markers do you mean you used a clapboard in production? I used to but then I switched my shooting audio and video (recorded separately on multicam shoots) with the use of timecode.
