I work for a DVD Authoring studio that specializes in digitalizing 8 mm film and other older formats for output to DVD. For the purpose of not having to re-render any material, the video is captured as Mpeg2 files. These files are later edited in DVD Author where flickerings and minor flaws are cut out. My problem is that some clients request the addition of background music, and I haven't been able to solve that since DVD Author somehow combines video and audio streams. The result is that wherever we have cut the video, the audio file is also cut by the same amount of time. Being new to Tmpgenc, I figured that if I output the edited video to an entirely new Mpeg2 file, I would sidestep that problem when I later add the audio, but I don't think that is possible to do. Are there other programs that would be better suited for our job? We want to edit the Mpeg file, add audio and then output to DVD without quality loss. I really hope that someone has a quick answer for me, since clients are waiting for results. Sincerly, Michael Nilsson, VIVID Digital Media, Sweden
I'd recommend using an MPEG editor like Womble Video Wizard to edit. Using a program like that you could save an elementary video stream with whatever edits you need. Then you can either mux it with a new audio stream in the MPEG editor or simply use the elementary video stream in DVD Author and add the audio in that program.
Thanks for the quick replies. Is there any quality loss when joining and re-rendering edited clips in the softwares you mention? How time-consuming is this workaround? (our schedule is cram packed). Thanks again, guys!
With a good MPEG editor you shouldn't be able to tell the difference between the original and the edited output. Generally speaking the time required is minimal, with most of the work being in copying data from the source to the output file.
