Burned DVD has no sound

[dkonnen]

I've done searches, and I'd appreciate any help.

I used VideoStudio V10 to create some sports highlights. I captured the clips from a digital camera, edited them in VideoStudio and set them to mp3 files. Then I used the share option to create DV avi files of the finalized footage.

When I watch the individual clips, they all have audio to them. Now I'm trying to create a DVD of the clips. I go through the process of adding them, creating a menu, but when I burn the disk, I have a problem.

Half of the chapters have sound, the other half don't.

When I create a DVD files instead of burning, there's no information in the AUDIO_TS folder, yet when I burn I get audio to some chapters. Help would be appreciated, because I like working with Ulead but if the problem persists, I'm not sure what I'll do.

First, the Audio_TS folder is going to be empty, so it is as it should be. Next using MP3's has caused problems, mainly due to poor codecs like the Lame codec. It is recommended to convert the MP3s to WAV files before inserting them into VS. They will need to be converted anyway (VS will do this, if you want to or not) to be burned to a DVD as MP3 is not part of the DVD spec. You can use a free program like Audacity. This can be found in our Ulead Products Tutorials Section, in the Free Stuff for Ulead Products Forum.

Or you can scroll down to the bottom of that page and find a list of Links to Freebies, to convert them.

I think that once you convert them before inserting into VS, your audio problems will be rectified.

Your work flow also sounds a little strange and may be contributing to your problem.

First, you do not say what format your original video is in. Next, I am assuming that you may be referring to video short with a digital still camera... or is it really a digitial video camera?

Next, you say you produce a DV file. This is fine if you start with DV format video, but there is little point in doind so if your video started in some other format. Hence my original question about the format of your captured video.

Just as the audio has to be converted at some stage, so does the video. DV is not the format of video DVDs. So at some stage your project has to be converted to DVD-compatible mpeg-2, and it is better done as a separate step after you finish your editing. You go to Share > Create Video File > DVD. There you will be given the options of standard high quality LPCM audio or compressed but still good quality Dolby or mpeg layer 2 audio.

Then when you have that new file, you close the project, and with a clean timeline, go to Share > Create Disc. This will open the burning module. You insert your new mpeg-2 file(s), create your menu and burn the disc.

I'm not using any mp3s in the final burn though. All the files I'm trying to put on DVD are AVI files with their own sound. Would that make a difference?

[Ron P.]

What flavor of AVI? AVI is a container, that can hold DV, MPEG-4, DivX, Xvid or MOV. You should be creating a DVD compliant MPEG-2, using either LPCM or Dolby Digital if you are located in NTSC area, or MPEG-2 audio, Dolby if PAL.

Why are you trying to put AVI files on a DVD? Are you trying to create a DivX DVD, or just trying to archive?

Out of curiosity, when you created the DV .avi files, were they DV Type-1 or DV Type-2

On the BURN step, do you get audio for all "chapters" if you check the "Normalize Audio" box

All original video was digital, captured through the Sony HandyCam through the DV port on the camera through the FireWire port on the computer.

When I talk about digital short, I'm referring to a 3-4 minute "highlight" like you would see on ESPN. Basically, we took the best highlights of sports teams and set them to an audio track.

I'll convert all the files to DVD files from DV files and try again. It still is odd that everything was compiled the exact same way, all the videos have sound when I view them on the computer, but only 4 of the 9 have sound when burned to DVD.

As Ken said, your process sounds strange and you haven't elaborated on it. Please read and follow the Recommended Procedure.

Correct me if I'm wrong here but doesn't that cause the mpeg2 files to getting re-rendered again? Therefore, the project properties in the burning module would need to be set to the same as the source files or smart-rendering will not work.

Hi MD,

The way I read the posts (that were available at the time I posted), it seemed like the OP was using DV .avi files in the Create Disc module
