Uneven audio in iMovie HD

There seems to be a serious problem in iMovie HD which wasn't in earlier versions. I like to add music (MP3s from iTunes) to a movie, fading it up and down around speech, which used to work perfectly, altering the Clip Volume. It still sounds fine in iMovie, but when I burn it in iDVD, the result is jerky, with sudden bursts of volume when it should be fading smoothly to silence, or into another piece of music. I have wasted 5 DVDs so far, trying to correct it each time. Can anyone help, PLEASE??!! Has anyone else found this?

Instead of wasting DVDs, try Save as Disc Image from iDVD. I believe you can open that as a disc and use DVD player with it.

Have you got any third party codecs installed like Flip4Mac? For some reason I think that one has caused odd issues for people.

Try exporting the movie as a Full Quality Quicktime movie and see if the audio problem still exists. If not, you should be able to import that file to iDVD and even iMovie if you have to fix chapter markers.

Irregular sound in iMovie on DVD

Thanks. Yes, I just tried that (disc image). Can you believe: when played from that, there is no sound at all, except for the iDVD menu At least my DVDs did have sound, even if it was cr*p!

I tried exporting from iMovie to camera, and then recording that on a domestic DVD recorder. The result was exactly the same, so the problem isn't with iDVD.

I believe it is a bug in iMovie HD, because I've done exactly the same process many times before with earlier versions, lots of music fades and cross-fades, and no problem at all. . . (You may seen one result, SPACE MUSIK, on my website at www.astroart.org)

Are both audio sources the same bit rate. You camera can record at either 12 or 16 bit. You're music import may not match. I've heard those type of differences can cause issues, but have no experience with the problem. When I've heard of that, it seems to to be a syncing problem as in timing with the picture.

Perhaps you should try copying the project, export the audio tracks, check them, and re-import them if they turn out well.

Also, Garage band is designed to do what your talking about. It is called ducking I think.
