DVD Transfer & Authoring?

[bvaz]

OK. I extracted the video files. Do I use SoundForge to sync the new audio with the video? Will this also get rid of the old audio?
I've tried doing this research on my own, but can't seem to find it. It has made my appreciation grow for all the people that go through all this to share on this site and other, not that I didn't appreciate it before.

Since he's a newbie - he should know that there's a good chance that he'll end up with .mv2 and .ac3 files after demuxing - and not a .wav file. Just depends on what's on the DVD.

Also - much of the advice given here is based on assumption that the new audio is the exact same length as the old audio. If VHS tapes are involved - the chances are next to nil that they are the same. The audio will have to stretched or downsized to match. This is very tricky business because after making the adjustment in an audio editor, it rewrites the audio file and *can* add some funky noises to the audio. I've developed a method for stretching the audio that works really well and doesn't require that the wave be re-written. But it's extremely tedious and time consuming. Also - even if you know you simply need to stretch/downsize the audio by 3 seconds and you do this in an audio editor - even that can be problematic because with some recordings there will be stretches that are out of synch, and some that are in synch. So if you simply stretch/downsize the audio universally by 3 seconds - you'll still have portions that aren't perfectly synched.

yeah stretch and pitch correct. use audition multitrack mode. and use time code to set your points here and in vegas. there is no nudging involved with getting videos in synch. VHS?? where have I heard that before.... some kinda primitive tool right? just kidding. It's really not that hard. Lots of hurdles. but any monkey can do it.

you don't need to pitch correct if you time stretch is properly

thanks for everyone's help. I think I am at least on the right track. I rendered the new file last night so tonight I re-author it and see what happens.

I think your right. I'll have to look into that. Seems like when I stretched stuff in the past, the pitch got slow/bassy. Seems to make sense though that if in one file 10 beats take 3 measures that if you stretched file b from 2.5 to 3 measures it should be at correct pitch since it also contains 10 beats. However, the theory doesn't seem to work with what I am doing. Maybe I'm doing something wrong. Anyone else have experience? Does anyone have to make adjustments to pitch after stretching for say a matrix or when synching two sources (real synch with timecode points)?

ok, the village idiot is back.
I was able to sync the new audio. then we I rendered the new file, it is just under 2 GB when I originally started with a 4 GB+ video.
I used DVD Decryptor to get the video files off the DVD. Then I coverted to a mpg file which was still 4GB. I used SoundForge to sync the new audio with video and then rendered in Sony Vegas.

anyone know what I could have done wrong?
thanks for all the help I have gotten already and any future would would be appreciated.

[AAR.oner]

you rendered it and it changed file size?

maybe you mean *re-authored* it and it changed size...if thats the case, you might have been compressing using a lower bitrate...i would check the preferences/settings and set it to ~8.5 Mbps CBR [constant bit rate] and if the new audio source is from a ***lossless source***, make sure to set the audio to PCM [or LPCM] and NOT ac3 compression.

What are some of the best authoring software out there, I've used nero vision express , but I don't really like their menu and chapters options, what is the best programs for making menues etc.

thanks for the info.

Best maybe. Easiest no way.

I have Vegas 4.0. I think the newest is 6.0. This is probably way more software than you need. This is professional stuff -- the kind of thing George Lucas probably has. It could take you the rest of your life to lean all of it's capabilities. I use Sound Forge all of the time and Vegas is way more complicated. But I am no expert.

I can't answer you question but I'd like to hear some other opinions.

I'm installing Pinnacle Studio 9 on my PC right now to play around with. I'm hoping it is better than Nero and less complicated than Vegas.

P.S. BTW, if you want to purchae a legit copy of Vegas 6.0 it retails, MSRP, for about $675.
