This has happened with many editions of Roxio, but only with some files. I have three cameras that capture video, but I do not associate the problem with any specific camera, though I may be mistaken.

Latest instance: a clip shot with a standard def JVC camcorder; an MOD file. When I play this MOD file with Windows Media Player, the sound is 100% good.

I open Videowave -- Videowave15.exe in this case -- and with media selector bring in that MOD file, and play the clip. The video is 100% good, but the audio is not. I have "experimented" with using Any Video Converter to process the clip just to convert the MOD file to other formats, such as m2ts and mpeg2. These converted files play OK with WMPlayer, but not when I bring them into VideoWave, then hit the play arrow. However, and this is astonishing to me, if I hit the TRIM button and then the play arrow, the audio is 100% good. This difference between playing the clip in the storyline and playing it in the Video Trimmer may provide a clue to those who understand audio codecs.

I know nothing about Codecs except that they exist, and in my ignorance wonder if my issue has anything to do with such functionality.

Creator 2012 and another competitor's video editing program open and play the mpg video clip with no issues. I'l try Creator NXT2Pro later. I would expect them to.

Can you upload a short clip of the mod file before you do anything with it? If you can't get it to upload to this site, upload it here (link). (Yaa.im)

Edit. I tried with NXT2 Pro and had no issues with audio.

That attached clip was trimmed in VideoWave to be short enough to be smaller than the attachment limit, but is an actual piece of the MOD file that would not play audio properly from the Storyline, but OK in the Video Trimmer window.

If you had no such issue, then the difference might lie with the audio utilities on the computer I am using. This would make the problem very hard for me to troubleshoot, but in my ignorance of the technicalities I would suspect that it had something to do with different codec utilities being employed in playing in the storyline and in Video Trimmer.

I cannot get a good MyDvD as it is now, when I try to include the clip. No use trying unless and until I can get VideoWave to play the audio properly.

My suspicion is that my problem lies in audio utilities on this particular computer. How might I go about troubleshooting along that line of inquiry?

By the way, I get hundreds of hits when I search my C: drive for "codec" which hints at the possibilities for complexity.

Ok, here is the easy way. Download a free copy of "Gspot" (I know, funny name) You can get it here (link) . Drag one of the MOD files to it. It will tell you both the audio and video codecs used and if they are on your computer.

Since the audio starts to play and then stops, I don't believe it is a codec issue. Are you going to upload a 10 second MOV file to that sharing site?

I did the Gspot thing, and nothing appears amiss.

How do I create a "short clip of the mod file before [I] do anything with it?" And then how do I identiify it as coming from me if I upload it via the YAA.IM link?

Why not record a short mod clip with the camera and upload to the website. Then post the link to your uploaded clip in your reply here.
