Voice out of synch

What causes voice to be out of synch with video on a newly burned dvd? And are there any fixes?

How did you go about burning the DVD? Did you follow our recommended procedure as discussed in your other threads?

If you produced a DVD-compatible mpeg-2 after you finished editing (Share > Create Video File > DVD), did you play the file back and was the audio in sync with the video in that?

If you did not do it that way, and instead put a video project file in the burning module, that is probably the reason as it could have gone out of sync during the conversion process which took place during the burning process. If you did it this way, then try the way I suggested in the previous paragraph.

If in fact you did first produce a DVD compatible mpeg-2 of your project and it was in sync at that stage, did you make sure 'do not convert compliant mpegs' was ticked in the middle of the three icons in the bottom left of the burning screen?

Steve thanks for the link, im trying to read through them.

Ken - Maybe i have been doing something wrong. I open my project, go to share, i go straight to create disc, do the chapter stuff and then select create image file (ISO). Then burn with roxio and i also tried IMG Burn. Did i screw up and not follow properly?

In the burned DVD the sound seems to start off ok but gets worse as time goes on. In reading through the link that Steve provided it seems like that may be an issue with VS. Since i am relatively new to video software and totally new to VS (don't fully understand much of the technical stuff) I would imagine I probably have some settings wrong.

If i understand you correctly you are suggesting that from share i should go directly to create a video file? Is creating a video file the same as rendering the video? And why perform this step if my video is already an mpeg file?

When you click on create video file there are many options. What do you recommend that i select? Once the video file is created what is the next procedure?

If you started with an mpeg and edited it, this may be the cause of the problem, as mpeg was designed as a viewing file type, and editing it can be problematic.

What do you suggest?

Post by **Ken Berry** » Wed Jan 16, 2008 9:10 pm

I have already suggested it: follow our recommended procedure.

1. Capture.
2. Edit
3. Go to Share > Create Video File > DVD to create a DVD compatible mpeg-2 of the project. Play it back on some third party software player to make sure the audio and video are in sync. If it is NOT in sync at that stage, they repeat the conversion process, only make sure that SmartRender is turned OFF.
4. Create a new Project (File > New). Don't bother giving it a name -- the objective is just to clear the timeline.
5. Go to Share > Create Disc > DVD to open the burning module.
6. Insert your new mpeg-2 in the burning module.
7. Make sure 'do not convert compliant mpeg files' is ticked in the central icon in the bottom left of the burning screen.
8. Build your menus and Burn either to DVD or to an .iso file or a DVD folder.

1. Can you tell me or maybe tell me where to find a good definition and the differences between creating a video file, vs. creating an Image file vs. creating a folder.

2. Is creating a video file a recommended process for all projects?

3. I presume they are all performing the same "rendering" function but saving them differently.

Thanks

You create a video file after completing your editing.
You then use that video file in the authoring stage.

At the end of the authoring stage you have 3 output options.

1. Burn to Disc.
The video is rendered and burned to a disc and you can also specify how many copies you want. Nothing is kept on the had drive in the way of a completed DVD s if at a later date you wanted to burn a few more copies you would have to wait for it all to render again.

2. Burn Disc Image.
This creates an ISO file on your hard drive. It is the raw image of a DVD and so you use that to burn off as many copies you want whenever you want.
You will not be rendering your video again.

3. Burn to Hard Drive Folder.
This creates an exact copy of the DVD on your hard drive that you can view with Windows Explorer. You can use a software player such as
PowerDVD / WinDVD / Windows Media Center etc to play the completed DVD on your computer. You can also use third party software such as MenuEdit / PGCEdit to make alterations to your completed DVD.
You can then burn off as many copies you want whenever you want.
You will not be rendering your video again.

I hope I¡¦m not beating a dead horse here, and I am going to use your advice but what am I doing when I go directly from editing to share and burn (either to disc, folder or iso)? Other then the audio synch not being perfect the video seems to come out ok?

I know this may sound naïve, but what is the purpose of creating the video file?

can i ask you an additional question. I just created a video file (mpeg2) and when i brought it into the share mode to make chapters, etc.. i noticed that the amount of disc space the data would need went down considerably compared to when I went directly from edit to create disc. Is that something that occurs when you create the file?

sjj1805 · Post by **sjj1805** » Thu Jan 17, 2008 6:47 pm

That is normal. When you go directly from edit to create disc then you need a certain amount of hard drive space to allow for the conversion of the edited project file to take place.

If instead you render a video at the end of the edit stage and bring that new video into the create disc stage no further conversion is required and so that additional hard drive space is not necessary.
