The process relies on residual chroma information retained on
cine-recorded colour TV programs, so it's of no use for film.
Personally, I recover faded photos by scanning them (with as many bits
per colour channel as possible), then re-levelling R,G & B in Photoshop
(16 bit mode). It gives you a pretty good result, & with some tweaking,
an excellent result - even on badly faded colour prints dating back to
the 70's.
