I’ve been digitizing our collection of oddball VHS tapes, generally without problems, always going from iMovie HD to iDVD from which I “burn” a disk image (File menu: Save as Disk Image) rather than a physical DVD, then burn one or more DVDs based on that image.
When the length of the VHS movie requires it, I “burn” to dual-layer DVD then use DVD2One to compress it down to regular DVD size and THEN burn to DVD.
I am having a problem with this one movie.
In iMovie it has sound, works fine. So no problem with the digitizing process bringing the sound in from VHS.
In iDVD when I “share” it, it again has sound when I click the > play button to get a preview of it. But twice now I have done the “Save as Disk Image” thing and the result has been a DVD diskimage with video but no sound. Nada. Zilch. Totally soundless. The second time around, I went into iMovie and did the Extract Audio (which usually fixes the occasional sound glitch) and saved the project and THEN shared to iDVD. Still no joy.
What could conceivably causing this behavior?
Between Attempt #1 and Attempt #2, I completely deleted the .dvdproj Project-package from ~/Documents so as to start fresh. Redid all the menus & everything. So presumably the encoded assets went down the toilet at that time and got re-encoded from iMovie.
After this movie failed to work, TWICE, I did a test; I had another extra-long iMovie project handy so I “burned” (to disk image) an iDVD project of that, to rule out a problem caused by something I had installed recently, corrupted setting, etc; and it worked fine. Has sound. Like the problematic movie, this one was also “burned” as a Dual-Layer project.
So it’s something specific to this iMovie project. It’s a bit SHORTER than the test-project that worked fine so it has nothing to do with being overlong. As mentioned before, I tried extracting the audio before Attempt #2 and that did not fix the problem. What gives?
