AV out of sync (DV500 DVD - Capture from VHS to DVD)

[cristiangatti]

Hi everyone. This is Cristian from Argentina.
I'm looking for help here ("dvdrhelp" seems to be the right place
Well anyway, these are the facts:

Problem: AV out of sync. Tried many things, still no solution.

Equipment:

Intel Pentium IV - 1.5 GHz.
256 MB Ram
2 Hard discs (1 for the system (40 GB), 1 for capture, it's always empty(60 GB))
Pinnacle DV500 DVD (I bought it 2 weeks ago... Still learning to use it).
Hercules Fortissimo II audio capture board
Winfast video board.

OK.

I don't have a DV Camera (which I don't even know what it is).

I only intend to CAPTURE Laserdiscs and VHSs (most of them on NTSC format).

I tried using the DV500 DVD capturing through DVTools and also through Adobe Premiere 6.5 from LASERDISCS, then export them with Adobe Mpeg Encoder and I got outstanding results. No frames dropped. No sync problems. I just got excellent quality DVDs out of my laserdiscs.

Now..., the problems started with the VHS capturing.

I tried capturing with excellent quality VHSs (like original ones) and there is no problem at all.
However, when I captured from old VHSs (even recorded in EP speed), I had a sync problem between video and audio (like 30 seconds in a capture of one hour.
I tried everything I know.
I also got this program called "ScenalyzerLive" and now there is no "sync" problems on the resulting AVI; the "new" problems are almost as annoying as the first one: Now the video jumps, and the audio seem to speed up all the time.
I understand maybe I'm misconfiguring this program. That's why I ask for help, cause I'm clueless about this.

I used to have a DC10Plus card, and never had this sync problem.
Now I have bought an over 500 dollars capture board, I have problems with AV sync...

It's true, DC10Plus dropped frames like crazy on old VHSs, and DV500 DVD does not drop not even one frame in one hour capture... BUT this is becoming more and more irritating.

It is not my intention to make you waste your time, explaining details or so, but I'll be more than thankful if someone here could give me a link to "hopefully" a place that will guide me to fix this problem.

I thank everyone so much. I'll be online for any help to come

Best regards from Argentina

Poor quality VHS tapes ... especially the EP/SLP speed tapes ... need what is called a Time Base Corrector or TBC for short.

There are really only two models to pick from that are inexpensive and seem to work well.

The cheapest full blown TBC can be bought from a website called avtoolbox.com for $179.00 US Dollars. This TBC is called the AVT-8710. CLICK HERE for a link directly to this TBC on the avtoolbox website

The other "inexpensive" TBC is made by DataVideo and it is called the DataVideo TBC-1000 and normally can be bough for around $300 US Dollars. Many different websites carry this product. You can try the B&H WEBSITE or the ELECTRONIC MAILBOX WEBSITE

Again these are just two of many websites where you can purchase the DataVideo TBC-1000

Most people seem to think the DataVideo is better. Most who have used the AVT-8710 seem happy with it but I have heard of a few people that haven't liked it but then again there some say they don't like the DataVideo unit either.

But that is really about it for consumer level TBC units. Professional models tend to go for $1,000 US Dollars and more ... I've seen units as high as $8,000 US Dollars.

Good Luck!

Hi FulCiLives
Thanks so much for your answer!
However, it is not an option for me to buy it now since I have to finish this job in the following next days, and it would take at least 1 week to reach me if I buy it. I have already tried finding it at electronic stores here in Buenos Aires (Argentina), but noone even know what it is...
So..., at least for now, I need to find some help through the "software" way...
Anyway, thanks alot, I'll buy it sooner or later.
Best regards

I've been thinking about this. Isn't it strange that the DC10Plus board (though dropped frames) gave an AV perfect-sync avi file? And the DV500 DVD board seems not able to achieve that?
Maybe I should go back to DC10Plus to do this job... I don't know.
Well anyway, any other help will be much welcome!
Best regards,


Cristian

Problem sorted out
"No Scene Detection" seems to be the right way to go. Capturing that way I got a perfect sync AVI. Exported to DVD format, still perfect sync, and quality seems to be the same as the VHS.
Hope this helps someone else Best regards

A brute force method is to simply transfer only 10-15 minutes at a time, with a few seconds of overlap, then stitch the resulting files back together again (best done with DV-AVI files, not MPEG2's). This way, you can remove the liklihood of sync problems being visible, and if they are, you can target a specific segment for 5 min blocks.

Hercules Fortissimo II audio capture board

Does this mean your video capture board doesn't handle audio, or is this just another name for a sound card?
