When I import video, I have no sound...

Any video that I take with my HD camcorder, no matter what the quality is, absolutely no sound plays when I import it into my software editing program, the files are in .mov format. The sound works with the original video, but when I import it, no sound. I don't even see a wave in the audio track. Again, the original video has sound. I have the latest version of quicktime. What's the problem?

What kind of camera is that? It is possible that Vegas simply doesn't support the kind of audio that your HD camera records at. To verify that, please shoot for me a 2 second video (no more than that), and send me the file, directly out of the camera, either at eloli-AT-hotmail-DOT-com or better, upload it on a server and send me the URL. I will take a look at it.

Ok, here is the video link: http://jamesfurlan.com/FILE0011.MOV

I don't understand, with other programs it works, but, when I export it, no sound plays. I even took the video directly from the camcorder, converted the format, and still no sound. I have an aiptek HD camcorder.

I can verify the problem. Vegas can't read that version of AAC that Aiptek is recording at.

1. Download SUPER from here http://www.softpedia.com/progDownload/SUPER-Download-23696.html (select the Romanian server) and install it. Load it. Right click on the application and set the “Output File Saving Management” to a folder that you would like to save your files to. This step needs to only be done once.

2. Now, drag n drop your MOV Aiptek files, onto the file area of SUPER, and make the app look EXACTLY like this: http://eugenia.gnomefiles.org/images/aiptek-to-mpeg2.png then, press "encode" (that's for NTSC 720x480). If you shot in 720p HD use it exactly like this: http://eugenia.gnomefiles.org/images/aiptekHD-to-mpeg2.png or the exact same for 1920x1080 too, but with 1920x1088 for width/height instead (everything else is the same).

3. In Vegas, it’s very important to have the right project settings before you start editing. Click “File”, then “Project Properties”, and a new dialog will pop up. In there, click the right outmost icon called “Match Media”, the one that looks like a yellow folder. From there, select one of the MPEG .mpg files you will be editing with (the ones outputted by SUPER), and click “open”. For the quality option in the "Project Properties" dialog select “Best”. Click "Ok".

4. Add these .mpg files on Vegas (not the .mov files), and edit your video as you would normally do. When you are done editing, export at 720x480 or any other DV/DVD 4:3 setting. If you recorded in HD, use 720p or 1080p exports or 16:9 DVD settings.

Alternatively, to lose as little quality as possible, you can purchase Quicktime Pro, and export in mpeg4 .mp4 h.264/AAC, which lets you re-encode only the audio and leaves the video unchanged (when you select "passthrough"). The problem with this is that Vegas is really slow editing .mp4 and .mov formats, so you are better off with some slight quality loss with the SUPER suggestion above.

Eugenia, Jimmy,
Thanks for investigating this problem. We do not currently support reading the AAC audio streams generated by the Aiptek cameras, but are planning to update our Quicktime plug-in to handle this format better in the future.

Eugenia,
Thanks for the workaround suggestion!
