Dear FrameWorkers,
can anyone shed some light on this predicament?
I am working on a documentary which was shot on film and which
hopefully will be finished on film but our intermediate will be in
HD. This is because the source material is in 8mm, Super-8, 16mm and
Super-16, at 18, 24 and 25 frames per second, but we are finishing
everything on 35mm 24fps.
We did a telecine last week of five hours of footage running off the
Spirit Datacine at 24fps. The goal here was to have every frame of
film (no matter what speed at which it was shot) to be resolved to
one frame of HD, and from there we can work on the cadence, as one
would on an optical printer, for example doubling every third frame
if it was shot at 18fps. I was convinced we were recording at 24PFS.
But I just learned the lab made a mistake and recorded everything at
50i. That is: 25fps interlaced.
I assume that means that the Spirit created an extra half-frame every
12 frames, and that even if we deinterlace, we will still not be able
to conform our HD timeline frame-for-frame with our film footage.
Is the best solution to redo the whole telecine transfer? Or does
someone know if two decks can be cabled together and a dub made which
will recalculate at 24PFS with no extra half-frames, and no loss or
digital manipulation?
Thanks in advance,
Pip
PS: stick to film, it's cheaper and easier.
