Bryan Mitchell March 26th, 2005, 04:53 AM I am getting similiar problems. I recorded some footage with my 9600 AIW card. I have 5 video files, about 15 min each. They are .mpg. I dropped them into Vegas, edited out the commercials, strung them together. They look fine in the timeline. When I export them as Video for Windows DV NTSC, the audio is way way off.
Right now, I'm exporting them seperate. I'm going to try putting them togther in virtual dub and hope that works. Hopefully it's not exporting them at different speeds (ie: speeding up the footage even the smallest amount in the export). Though... it doens't get progressively worse in the file. It's only after the first edit point. So the first 15 min are fine. Then its all way way off.
Brent Marks March 26th, 2005, 07:18 AM Comon guys...?
Anyone...??? We need help here...
This has to be a common simple problem?
How can we fix it
Edward Troxel March 26th, 2005, 08:34 AM Bryan's problem I can understand. Capturing via an AIW into an MPG is not a good option. Much better to use an external convertor and capture to DV-AVI. Then all his problems would go away.
Brent's problem - could you explain a little more? Are you doing hdv?
Brent Marks March 26th, 2005, 10:02 AM Shooting on HDR-FX1...
capturing HDV using Cineform Connect HD
capturing to m2t file...
Dropping the m2t file onto Vegas timeline
then doing a simple render out to mpeg2
HELP!
Jack Smith March 26th, 2005, 04:09 PM Have you tried converting the audio to the project settings then putting it on the timeline ,syncing it with the existing audio, turn off the events audio ,then render?
Brent Marks March 26th, 2005, 04:42 PM no, i have no clue as to what u just said...
why would i need to do all that?
can't vegas handle it?
Bryan Mitchell March 26th, 2005, 05:38 PM See the thing is.... After several tests.... It's the Video that is off. Not the audio. I exported each seperatly, then played them back. The audio played back beautifully, with no sign of the cuts. The video however, had parts of the commercials I had cut out, along with alot of other really weird side effects. For some reason, even though I cut it, and even though it looks fine in the timeline, IT's exporting the video differently than I have cut it. It's 45 min long... And only 1 vid track, 1 audio track. This is absolutely ridiculous....
Brent Marks March 26th, 2005, 06:31 PM Anyone...?
HELP
Dan Euritt March 28th, 2005, 12:17 AM bryan, it sounds like vegas isn't combining the mpegs correctly... download the womble demo and see if it'll put 'em together and keep 'em in sync... but ed is right, you shouldn't even be using mpeg as a capture format... unless it's hi-def off of a cable feed?
David Ennis March 28th, 2005, 06:19 AM Brent,
I guess the problem is that not many people are working with HD (including me).
If you have confirmed that the audio is in synch on the timeline, try rendering the project to .avi first. You're demanding less of the program when you do that. Once you have it in .avi rendering to .mpg should be smooth.
Another option along the lines of Jack's suggestion above is to try rendering the audio alone into a .wav file. Then add that wave file to a new track in your project. Make sure it's in synch, mute or delete the other sound track and render.
Brent Marks March 28th, 2005, 08:49 AM My final product doesn't have to be HD....
I just want to maintain the quality and the 16x9 aspect ratio.
What's the best way for me to capture/edit?

Brent Marks March 28th, 2005, 11:13 AM How are you guys editing then???
What am I missing here?
Steve Roffler March 28th, 2005, 08:49 PM Most of us are capturing DV-AVI and editing in that format. Then you render to whatever you want.
Brent Marks March 28th, 2005, 11:48 PM How exactly do you capture DV-AVI from the HDV tape/camera?
thanks
I didnt know you could capture HDV to DV
Steve Roffler March 29th, 2005, 03:15 AM As I said, most of us are capturing DV-AVI. That means we don't have a HD camera (wish I did but they are too expensive for my needs).
The links posted above by Edward tell you what you need to know. You will have to do some reading and research. Then you can tell US how to do it for the day when we all have HD cameras ;)
Bryan Mitchell March 29th, 2005, 06:08 AM Well, I capture all my DV footage that way too.... however.... I am talking about capturing the TV (ie:tivoing) with my ATI9600 All in Wonder Card. I don't believe I can capture it as non mpeg with my current software. (And I can't record this show again) I want to edit out the commercials, and compress it. I used someones earlier suggestion of using MPEG Video Wizard. It worked great, but now.... when I try to compress it in cleaner or virtual dub, the sound and audio are off in that!
Edward Troxel March 29th, 2005, 08:23 AM Bryan, your case is totally different. As I said before, using the AIW to capture is simply asking for trouble. Editing in MPEG is asking for even more trouble. Save yourself the trouble and capture DV-AVI via firewire through a convertor instead of trying to use the AIW card.
Brent, I don't have an HD camera so, as Steve said, I capture DV-AVI from my MiniDV source (Canon XL-1, Canon GL-2).
Bryan Mitchell March 29th, 2005, 09:39 AM Edward. How do I capture video from my cable line (cable tv) into my computer via firewire? What product would you recommend, that can convert the live TV signal to a firewire connection/cable/card in real time?
I'm wondering if I could record TV into my XL1s using the RCA cables.... But I would need some kind of converter from coaxle to rca. Then I could later capture and edit this footage with ease. Hmmm.. Still, I couldnt schedule this when I was at work.
I am trying another encode right now by different processes. The early recommended mpg programs solved the editing problem, and in fact render the new cut in about two minutes, which is awesome. The hard part is now getting it to encode into Xvid without losing the audio/video sync. I'd say this is more of a general mpg2 problem, than anything in vegas... so perhaps I should post this on another board.
I'm using virtual dub right now to encode it. It looks to be working but only time will tell :)
Thanks for everyone's help on my issue. Hopefully Brent can get some help on his.
(Mpgs suck!)
Edward Troxel March 29th, 2005, 09:52 AM You have SEVERAL options. First, you need to get the coax to either S-Vid/Rca or just RCA/RCA. From there, you can:
1) Hook it up to your camera, hook the camera to the computer via firewire, and let the camera convert from analog to digital while you capture standard DV-AVI
2) Hook it up to a convertor (such as the Canopus ADVC100), hook the convertor to the computer via firewire, and let the convertor convert from analog to digital while you capture standard DV-AVI
3) Hook it up to a deck, hook the deck to the computer via firewire, and let the deck convert from analog to digital while you capture standard DV-AVI
Dan Euritt March 29th, 2005, 04:13 PM <<<-- Originally posted by Bryan Mitchell : I'm wondering if I could record TV into my XL1s using the RCA cables.... -->>>
it would be foolish to wear out an expensive xl1s capturing t.v. footage.
are you aware that all the major t.v. programs are easily available for free on the 'net? they are already encoded in xvid, ready to burn to a cd.
Bryan Mitchell March 30th, 2005, 07:36 PM Who do you think is putting them there? In Xvid...
Btw, I got it all encoded. I found the right programs that let me do it, and it works great now. Thanks for everyones help.
I don't see how it would be any more foolish than filming for 45 minutes... And I'd only wear out the heads. That's only a couple hundred for the repair, and it's under warranty anyway. It's not near as foolish as capturing footage from your XL1s to your computer, when you could use a cheap $300 camera... and a "deck" is what I use. That would just be pointless. But I don't think my smaller camera has AV in... but maybe it does. However, I already solved my problem another way, so I don't need to.
Dan Euritt March 31st, 2005, 12:08 AM just today i dropped my xl1s off at canon irvine to get the drum replaced... the estimate was $380, not "a couple hundred."
i lost irreplaceable footage because of this head failure, no warranty will save you from a sudden failure in the middle of a shoot.
when minidv cameras are going for $250 or less brand new, it's crazy to waste an xl1s on something silly like tv footage that can be downloaded off of the 'net.
Bryan Mitchell March 31st, 2005, 08:50 AM $380 is a couple hundred to me. Heck, I thought the repairs were more than $500. And you clearly did not read my post AT ALL. Try again.
A) I already said I use a $280 miniDV camera to capture my footage, but I wasn't sure if it had AV in.
B) I already said the problem was solved, so I don't need to "waste" my XL1 on recording it.
C) I asked you, who do you think is putting tv footage on the net for you to download? Is it appearing magically? Because the studios don't do it. It's illegal. There's something called advertisers which pay for the broadcasts, and when those are cut out, it's not very beneficial.
D) An hour of recording on an XL1 is NOTHING compared to how much I use it during a shoot.
E) Sudden Failure of my XL1 is not going to result from using my XL1s to capture TV footage, any more than it's going to happen capturing footage for my movie.
E2) Did you capture TV footage using yoru XL1s? It sounds like you never would... yet yours failed... Are you saying it could fail by just shooting normally? Oh yeah! That's what I'm saying too!
F) You seem like you just want to argue an issue that's already resolved, as if I'm incompetent, and unable to comprehend what you have already said once, and failed to sway me about.
