New DVD used to be in synch...?

[KennethS]

Howdy,

I recently did some very modest editing of a DVD, and then
burned a new DVD for my work.

It played perfectly on both my desktop, and my laptop.

Then, I used it with a client, and when it played on their
equipment, the audio and video were significantly out of
synch.

How might I avoid that sort of problem in the future?

Sincere thanks,

Welcome to the forums. It is impossible to help you because you have not provided enough information. Unfortunately, many new members here seem to think that the less they say about what they did, the more likely they are to get help. It is actually the opposite. What you have done is equivalent to taking your car to a repair shop and saying "Something is wrong with my car, but I'm not going to tell you what it is. I do expect you to fix it."

We need to know -
What did you use to edit the DVD?
What did you use to re-author the DVD after editing it?
Did your authoring program re-encode the video after you edited it?
What kind of changes did you make - for example, did you simply remove something?
You should be aware that depending on how you do the edits, some editors actually can introduce sync problems into video when you remove video. Although this is counter-intuitive, with some editors what you actually have to do is mark the areas you want to keep NOT the areas you want to remove, save those areas to a clipboard, and then join them together in a new file. If you use some editors to remove video from a file, the act removing can introduce sync problems, but it depends on the editor you use.

Howdy,

Please accept my apology for the lack of detail...

Here's what I did:

I copied a DVD to my system using DVD Fab HD Decrypter.

Next, I removed a few sections using DVD Shrink 3.2.

That created a new file that I burned to a new DVD using Nero.

When I played the new DVD on two of my systems, it played fine, but when I played it at a client site using their equipment, the audio and video were significantly out of synch.

Sincere thanks,

Kenneth

Did you test it in on a standalone player, or only on PCs with software players ? The experience can differ with software players.

What media did you use when you burned the disc ?

Howdy,

The disk was branded, Memorex perhaps. If you need the specifics, I can certainly check.

No, I did not play the DVD on a stand-alone player until I was at my client's site...

Thanks for any further thoughts,

Kenneth

Memorex don't manufacture, they rebrand discs from several different sources - most of them poor quality ones at that. If you are working for clients, use good quality discs - TY or Verbatim would top the list.

Secondly, always test on standalone equipment. Standalone players generally have lowest common denominator features and minimal error compensation. Software players often have higher levels of error correction and other trick sup their sleeves that can give a false sense of security.

Finally, if you are working for a client, use better software. Yes, Shrink can make some small cuts, however it is not an editor, and it is not an ideal solution. When you use Shrink to cut a video, what you end up doing is breaking it down into smaller titles, which will have delays between them, especially on standalone players.
