i thought i was computer savvy, but for the life of me i cannot seem to figure out how to sync audio/video w/ TMPGenc. i have searched here, dp.com, & dvdrhelp.org til i was blue in the face. some step by step instructions would be sweet. btw i hope this is the right forum for this.

try vegas video

i "tried" it but i could not get the plug-in for mpeg2.

then you have..wait, mpeg2 ? pardon my ingnorance, but is that for vcd's ? or Svcds ?
-
Mpeg 2 is the standard for most DVD's. Mpeg 1 is standard for VCD. I'm not sure what you mean by "i couldn't get the plug-in for Mpeg 2". Vegas should come stock with all the codecs you need. What version are you using? This doesn't help that problem but i find it easiest to find the 1st vocal & mark it on the original tape then find the same spot on the new audio & mark it. Subtract the difference & then line 'em up. Once you get them close to in sync you can listen to see if they match up nicely(no echoes). If they don't take a frame @ a tme off until they do.

vegas video requires you to register w/ them online to get either mpeg1 or mpeg2 plugins. trust me. i am using TMPGenc. the files i have are mpeg1 for vcd. my first goal was to sync w/ audio and convert to mpeg2 for dvd. that seems more difficult so i could keep them as mpeg1 and make vcds which seems a little easier. i just cant seem to get them in sync.

adobe premier? I'm sure you can find a free copy online

An easy way to synch is to extract the crappy audio from the camera into a wave file. Then line it up with your good sound in multitrack (as if you were doing a mix). You can see exactly where you want your audio to start and how much drift there is between sources. Edit your good sound to match the crappy one (same start and end points), then 'mux' them (stick em together) with tmpgenc by using your wave file as the audio source.

sweet dood. gotta try that. should i use wavelab or soundforge? thanks a ton. oh and +t!

you should use cool edit pro. it has an easy interface.

This link has been very helpful for me. ;)

this is the route I go. Extract the cam audio in tmpgEnc as one .wav...drop it in cool edit pro multitrack, then mix in the good source, song by song. Mute cam audio when I'm done, and mix down. I use dvd-lab to author, so I mux it back with the video at that point, finding chapter points by getting the time for each track on the audio mixdown, then inserting them via the timecode in the video preview. Very easy, very fast, works like a charm.

Any CoolEdit Pro users who have succeeded with this, I'm looking for some tips. I find that when I stretch my external audio to match the length of the camcorder audio, the external audio becomes slightly garbled and distorted. I'm using the constant pitch option (i.e. adjust tempo). Also, I'm using the constant stretch tab, as opposed to the gliding stretch tab in Cool Edit. Am I doing this right? Any guesses on why the audio quality would deteriorate after it's been stretched??
-
the audio from the cam should be visible in vegas. you can then bring in your good audio wave and overlay it/sync it, whatever.
you should then be able to save it as the huge uncompressed avi file, you could then load that file in tmpgenc and encode to mp2.
i have the codecs for mpeg 2 in my version of vegas - i dunno if its possible to send them to you, but if you know of a way, i'll be more than happy to to help you thru this "learning experience" ;)
-
The problem I'm having though is actually the overlaying/sync'ing part. I use Pinnacle Studio for the video editing/layout, and Cool Edit Pro for the audio editing. I'm taking the camera audio from Pinnacle and importing it into Cool Edit Pro so I can sync my better quality external audio with the camera audio, and then replace the audio back into Pinnacle using the superior audio. Problem is I'm having trouble actually stretching my external audio so that it sync's exactly with the camera audio. The sound quality seems to suffer after I run the audio through the "stretch" function in Cool Edit Pro and I don't know why that's happening...
-
you might want to cut each song into its own track and then line up each track to the cameras audio. i have this problem on occasion too. but i try to mix in the camera audio a bit inbetween songs if i'm having a problem with synching.
this way the better quality audio only has a few minutes (or however long the song is) to get out of synch not a full show.
-
Cool, that's not a bad idea. Thanks for the tip.
-
no problem. or if the camera audio is bad, even too bad for the clapping inbetween songs where the other source is spliced and theres a gap, you could always make the clapping between the songs its own track and stretch that. it'd probably be less noticable than stretching the actual music.
-
Right! I figured I could just use the clapping inbetween songs from the superior audio source and tweak that a little because it would be less noticeable. Sounds like song-by-song is the best way to sync up audio. Too bad it'll probably be a much more laborious process..
-
its not too bad, i did a sbd/aud matrix this weekend and it took me under 2 hours to do it (only a 45 minute set tho). however, video is a bit harder.
-
I've used Audacity before for quick jobs. Shows that run long 2hrs + seem harder because the songs near the end tend to be more out of sync. Syncing each song or a couple of songs would be the way to go for me for long show recordings. Could be my camera is getting old.
Vegas users can buy a plug in called Excalibur 3.0 to help syncing up audio with video. I mainly tried the demo for it's multiangle use but syncing the audio is as simple as dragging the wav to the desired trim. I haven't tried this yet but sycing the audio to video for a song was very easy. Just match up a point in the video of a cymble crash to it's audio and Excalibur syncs it up. Matching up multiple videos is easy when hunting for a camera flash. :-\ Humph, I really should cough up the C note for this plugin. You can download a working demo and use it for 15 days. Well worth the effort for any vegas users.
