Burning disk does not include audio

Hi -

I created a slide show video including images, titles, and audio. The audio is a .wav file. When I burn the DVD, the rendering does not include the audio. Otherwise it is fine. I'm puzzled since it seems like when I burned the DVD the first time, the audio was there. But then I changed the audio track and now when I attempt to render (burn a new disk), there is no audio.

Thoughts?............thanks in advance.

What are the properties of the wav file?

What are the audio properties of your output file?

Jeff -

When I click properties in Video Studio for the audio track I get "Microsoft WAV files", "56 MB", compression "'PCM", 44.1kHz, 16 bit stereo, about 14.5 M samples. I have (3) of these tracks in my presentation.

I'm not sure how to get the properties of the output (rendered?) audio.

I also notice that the rendering does not include additional slides I've appended to the previous rendering. The original was about 6min, this presentation renders at 6min; but when I play from the timeline, it runs about 13min. The sound also plays ok from the timeline.

By the sounds of it, you are not following our recommended procedure of doing your editing, then first, while still in the Editing module, going to Share > Create Video File > DVD to produce a DVD-compatible mpeg-2 of your project. That way, you can play it back and will know immediately if you have the audio.

Instead, I think you are doing your editing, then going immediately to Share > Create Disc > DVD. The burning module opens and your *project* file is in the burning timeline... That way works for some people all the time, but for many others, it doesn't. So try the workflow suggested above...

Ken -

Are you saying I can't do editing, title, effects, audio, etc in a random sequence? If so, does that mean I now have to go back and recreate the presentation from scratch? Also, if I can't slice and dice the sequencing, how do I insert images, titles, etc., after a share -> disc burn has taken place?

No, I am not saying that at all. What I *am* saying is that you do all your editing, in whatever order you like. And when satisfied with the way the project looks, you convert it to a DVD-compatible mpeg-2 which you can then burn to disc as a separate step.

You of course save your project file so that, later, if you want to add something to it and produce a new DVD, you can. You simply open the project file as normal, add your extra files or change existing ones (as normal), but then finish that new editing, save the project file, and produce the new mpeg-2 which can then, again in a separate step, be burned to disc...

The extra time taken in this recommended workflow is really only a couple of seconds (to key in the Share > Create Video File > DVD command and, when you eventually open the burning module, to Add Media to insert your new mpeg-2). But no more than that. In the recommended workflow, the conversion to mpeg-2 takes place as a separate process in the Editing module. In the workflow you are using, it still has to take place -- and will take exactly the same time for the conversion. But it takes place as a sub-set of an already complex process of multiplexing the video and audio, converting the menu to video and the actual burning.

For some computers, this added burden during the burning process seems to be a bit too much for their computers to handle well and something, as in your case, seems to fall over in the multiplexing of video and audio...

Ah.........an epiphany. I think I see where I've been straying from the path. I haven't been creating the video file before doing the burn. Thanks for kicking me in the right direction.

Glad that the Road to Damascus was short in this case!!
