JC & Rob,
Some advantages of doing a stabilized transfer over doing the
stabilization in post (Flame or Henry) are 1) minimizing video processing -
if you're using a compressed format (DCT, DigiBeta, etc) the pixel shifting
done in stabilization will give you a (very slight, admittedly) hit when
recompressing. Ampex and Sony demoed their compressed dvtrs using pixel
shifting (H&V) to show worst case degradation in multigenerations. Bottom
line - a very minor effect, more theoretical than visible.
2) If you use Flame for stabilization you need to worry about the
degradation from 601(YUV) -> RGB -> 601 color conversions. This is a much
more significant effect and can be very visible and objectionable depending
on program material.
3) Blanking - post transfer stabilization of images implys that the
blanking will now be variable. Depending on the material and degree of
stabilization required this can be very minor(nanoseconds) or major
(microseconds). If the telecine is well maintained and the film is in good
condition then it will generally not be significant but is something which
should be kept in mind.
