our needs and I understand this better now. The "close enough for
jazz" concept doesn't quite work when we labor on every frame in our
Will the original transfers to digital need to be done on a frame by
frame optical printer type set up? Or will master files done on say a
Rank or other telecine machine now be later useable when the blu-ray
or HD technology is affordable for "avant garde style" filmmakers.
Eg. will we have to start the process all over again with the first
stage film to digital transfers? Assuming we save the original files
done before compression.
