Yes it does. I have only a handful of 35mm shots done at 1080p for Empire, so I can do v2.5 at 1080p in the manner described above, only render the movie at 720p for v2.5, so I wouldn’t need to replace the 35mm shots already done at 720p for v2,0 and then keep the 1080p timeline ready for v3.0.
I was also wondering - has anyone written AviSynth scripts to conform the BD to NTSC GOUT sync? That would make my work much easier! 😃
