Losing sound when making mpeg file

Hi! Just upgraded to Movie Studio Vegas 6 yesterday and have a problem. I made a movie in the mpeg(2) format.

However, when I play back the file, there is no audio.

I never had this problem with Movie Studio 4. Unfortunately, the files are not compatible between the 2 versions.

I haven't tried the avi format yet as I started rendering it last night. I'd prefer to stay with the mpg format anyway.

Does anyone have any ideas? Thanks.

Can you hear the audio when you're previewing? It's possible you've muted it. If you can, then check that you're not rendering the mpeg as an elementary stream - that doesn't include the audio.

Just spotted you're an experienced user - sorry if I'm teaching granny to suck eggs!

Yes, I can hear audio during preview. I used the main concept mpg-2 option. The audio shows up in the description box as
Audio: 224 Kbps, 48,000 Hz, Layer 2
Video: 29.97 fps, 720x480
Use this setting to create an MPEG-2 file with an NTSC DVD-compliant video stream, and an MPEG layer 2 audio stream.

This choice worked well with Studio Vegas 4. I tried the avi format to see if I would have sound, and I do have sound. Can't figure out why there is no sound with the mpeg-2 format.

No problem - not a granny yet!

This may be normal; when I'm rendering prior to putting my files into DVD Architect to create a DVD, I render as MPEG2 (using the "DVD Architect NTSC video stream" template). The resulting file has no sound. I then have to re-render the sound separately as a .wav file (48KHz 16-bit stereo PCM). These can then be pulled into DVDA without problems.

In other words, I think what you're seeing is intended behaviour. I don't know if there's a template setting in VMS6 that'll create an MPEG2 with audio included...?

MPG with audio included can be generated from the 'save to disk' selection of 'Make Movie'.

How did you generate the MPG which turned out mute? 'Burn To DVD' will generate seperate audio and video streams for DVDarchitect

Thanks for the replies!

I saved the mpg to the hard disk. I have an external hard drive that I save videos on and then make the dvd with a collection of videos.

I didn't have this problem with VMS 4. I've tried it several more times with MVS 6 and I still have no audio.

I just upgraded to 6 and I'm not really impressed right now. I must be missing something on this upgrade.

What version do you have? I seem to remember having this problem when VMS 6 came out. They issued an update, VMS 6.0a, which corrected the loss of audio problem. HTH

I do have VMS 6.0a.
