Get PhotoToMovie to create a DV stream and import that into iMovie. Job done.
Once you have timed and arranged and manipulated the photos to your liking in Photo to Movie, it exports the file to iMovie as a DV stream. You can add music in Photo to Movie, but I prefer doing this in iMovie where it is easier to edit. You can now further edit the slide show in iMovie just as you would a movie, including adding other video clips, then send it to iDVD, or Toast, for burning.
This slideshow is actually going to be used as the background video to the menu of a DVD created in iDVD 6.
I infer from what you are saying that iDVD's "native format" is DV and not Apple Intermediate Codec or H.264 etc.
Now that you mention it, of course that's the case.
One can actually export directly from P2M to an "mov" file using the DV Widescreen codec.
If I've got the slideshow already edited and tweaked the way I want it in P2M, would exporting it to iMovie HD 6 as a DV result in any improvement in visual quality?
It's the visual quality at this point that I'm concerned about. Using AIC resulted in an improvement (fewer "jaggies") than H.264. Perhaps DV Widescreen will be even better than AIC.
Many thanks again for responding! It's guys like you that make this forum an incredibly helpful resource.
