sorry, i haven’t looked at the video,
but a blink replacement would take about 5-10 minutes to do in FCP7
if the head is turning it’s harder and may not be possible.
a WINK is not blink, and may not be possible as the face scrunches up too much.
my process is:
take the last good frame of the eye before,
make a freeze, put it on V2
track the eye to the head by turning freeze to difference mode, and key framing,
use an eyebrow, say to track.
do the same with the first good frame of the eye after the blink.
put it on V3
do an dissolve between the two freezes, from the before-blink to the after-blink frames.
usually i do an opacity keyframe rather than a dissolve.
over this same duration dupe the V1 section on to V4
use an 8-point garbage matte around the eye area. (generally looks like a Zoro mask!)
