Idvd Audio Problem, Will Toast Fix?

[jluecke]

I am having a problem with iDVD which is well documented online.

I have imported and edited hours of footage in iMovie, I'm actually transferring VHS footage onto DVD for my parents. I'm working with about 30 hours of video.

Everything looks great until I either burn a dvd with iDVD or export to a disk image or a video_ts folder. In every case the audio gets out of sync near the end of the videos, which are about 2 hrs. each.

I've learned through internet searches that this happens because my imported video is 12-bit audio versus the 16-bit needed for iDVD to do long movies.

 

My question, I'm sorry for the long build up, is whether toast can burn dvds using my current iMovie projects with 12-bit audio and keep the audio in sync.

If so, it would be well worth the purchase over having to do some other solution involving totally reimporting all this footage.

 

Thanks!

I don't know if it will be different using Toast. The audio must become 16-bit for the video DVD spec. Toast encodes as AC-3 audio instead of iDVD's PCM/AIFF audio so that might make a difference. One difference it does make is that Toast uses much less disc space for the audio so the video can be encoded at a higher bit rate for movies longer than an hour.

 

If you want to test Toast, Roxio has a refund policy for a certain number of days when purchased as a download from Roxio's site.

 

Thanks for the info. I've downloaded Toast and I'm burning a DVD as I type. I'll post back later with the results.

Nope, it did not work, I am still having the same audio sync issue I had under iDVD.

If you have QuickTime Pro I can think of a way that might put the audio back in sync. Let me know if you want the details.
