No sound on created DVD with 11+

[JeffFinnan]

I just created a dvd with several short movies. The background sound works. However, there is no sound in the individual movies. The video part looks just find. When creating the disc, I checked performance using Preview. The sound was just fine there. I did this a second time to see if there was something obvious I did not do correctly. Nothing appeared obvious though. There is no sound through computer or in the dvd play connected to the tv.

When I look at the files on the dvd, the video_ts folder is empty.

Any ideas?

Thanks,
Jeff

When I look at the files on the dvd, the video_ts folder is empty.

I assume you mean the AUDIO_TS folder? The AUDIO_TS folder is normally empty. The audio and video are multiplexed together in VOB files in the VIDEO_TS folder.

I think the AUDIO_TS folder is used for special audio-DVDs. (I just bought an audio-only DVD, and I'll have to check it out.)

What format(s) are your original files? Are you joining these files together, or are they separate titles on the same DVD? The Read This First post at the top of the forum tells you what we need to know in order to help you.

Some compressed* formats can sometimes cause trouble, especially if you edit them, or if you combine several different formats.... You may need to convert the files to a less-compressed format as a first step.


* Almost all video formats are compressed, but the less-compressed formats cause the least trouble. AVI/DV (13GB per hour) is almost always trouble-free.

The video_ts is empty? how could that be when you can watch the individual video clips?

I made a new DVD watching every thing I did:


Properties of your source files (format, file size, where did you get it?)

I used avi format

What devices are involved and their mode of connection?

I used a miniDV camera to provide several short segments. I connected it via 1394 cable and transferred using the capture option in VS11+.

Project Settings

NTSC drop frame (29.97 fps)
Microsoft AVI files
24 bits, 720 x 480, 4:3, 29.97 fps
Lower Field First
DV Video Encoder -- type 1
PCM, 32.000 kHz, 16 Bit, Stereo

Output format (file, DVD, VCD, SVCD)

I trimmed the segments a created new avi files for each trimmed segment. Using Share > Create Video File > DV > NTSC DV(4:3)

After creating my trimmed avi files, I created a DVD with these trimmed avi files with no motion menu and no background. Preview showed segments working fine with sound.

Error Codes (if any) None

There is no sound on the segments on the created DVD. Background music in the menu worked.

From your project, try producing a DVD compatible MPEG2 file (Share>Create Video File) NTSC, DVD, instead of another DV (avi).

Although it is possible to author your DVD using VSP, or DV (avi), or other formats, they must be converted to MPEG2. So why not get this out of the way before authoring your DVD. This will lessen what your PC has to do in the Burn Module.

It may not be what is causing your sound problem, but worth a try. Generally the lack of sound is due to a TBYB version being used, which lacks Dolby Digital support.

That's an out-of-the-ordinary combination -- usually it's 12-bit 32khz, or 16-bit 48khz. Yours seems to be a combination of the two.

If you don't need 12-bit 32khz, I would recommend changing your camcorder default to 16-bit 48khz.

Something to try -- when you create your DVD, is there a "Normalize" button (I'm away from my editing machine). If you see the "Normalize" button on the last steps (burning module), try selecting that option to see if it makes any difference...

Okay, did this and it worked.

Thanks much,

I am pretty sure this what was given as the default but have now gone in and changed it. I have to check to see if this is another way to resolve the issue.

Thanks much,

I noticed it significantly speeds up disc creation.

Got a question or two on capture.

In my very first attempt, the file created was an mpeg when capturing from my camera. My first thought this was part of problem so that the next time I had the capture set for AVI.

My thinking as flawed as it may be is that I should not compress until I need to. Is this the right way of thinking? Space is not a problem and why make the computer work at compressing when it is hauling in all this data.

If I were to capture a MPEG, what are the best settings?

Thanks,
Jeff

You got it. If at all possible capture to DV-AVI, then render once to MPEG-2 for burning to DVD.

[JeffFinnan]

If you don't need 12-bit 32khz, I would recommend changing your camcorder default to 16-bit 48khz.

After I changed it, I tried making an AVI file and using that to create a DVD disc rather than making MPEG2 file which I now know works. This time the sound did work. It was the 16-bit 48khz.

Thanks to all who had input.
