I render with Kineme's Quartz Crystal, which is particularly excellent: http://kineme.net/product/QuartzCrystal
Then I open both my audio file and my movie file with QuicktimePlayer/Quicktime Pro (still running the older Quicktime app with the Pro extensions in addition to the default Quicktime X). I "select all" on my audio file, and "copy". The I bring focus on the movie file, and choose "add to movie". Then I export to whatever file type I want. That's pretty much it, since I usually program fades, titling, etc. with QC. If I need to do anything more complex I use Final Cut, but that's kind of overkill for adding audio to a movie file. -GT On Fri, Oct 1, 2010 at 7:02 PM, Rua Haszard Morris <[email protected]> wrote: > Aha - Indeed this is very accurate!
