hi chris,
to create a BD from a MOV-file is simple, but in your case it´s not possible because of the BD-specs.
720p24 is not part of BD-specs, you should go 720p60 or 720p50 (for europe).
if your source-film is shot on 720p24, you can upscale it to 1080p24 and conform it to 1080p23.98 for use within encore CS4.
this is necessary, because encore CS4 can´t handle 1080p24 as it is part of the BD-specs, it could only handle 1080p23.98.
with encore CS5 it is possible to use 1080p24 as well.
so your workflow should be as follow:
1. export self-contained from FCP
2. upscale to 1080p24 using compressor or mpeg streamclip
3. conform the mov to 1080p23.98 using apples cinema tools
4. encode the file with the new chapter-marker (using compressor)
4. import the asset into encore
if you would like to have chapter-marker at a specific position you need to import the MOV into encore and set the chapter-marker over there as well, it cant read out chapter-markers out of a MOV-file.
NOTE: if you´re conforming to another frame-rate you´ll loose all your chapter-markers, in that reason it is necessary to re-set them.
cheers
