Okay, I tried the technique listed above. Here's a low res version of it:

I tracked the eyes with Mocha, changed them in After Effects, then used Optical Flares to give them that special ethereal glow/shine. |
.. how long did it take you to do this (assuming you are an experienced video-editor)?
just curious .. |
Maybe 2 hours. I spent probably 20 minutes or so tracking the eyes in Mocha (it did a good job but there were a few points where it lost the track and I had to keyframe those individually), then maybe another 30 minutes or so fiddling with the eye color and the glow (which, as it turned out, I decided to trash in lieu of the optical flares), then another 30-60 minutes deciding which flare looked best, adding it and keyframing it. I could have done the keyframing of the flare location quicker but I was waiting on a phone call so I decided to do it manually to give me something to do. I'm guessing that if I had all my ducks in a row, I could probably have done the whole thing in 30-40 minutes or less.
For a shot like this, it COULD be done manually from the start and wouldn't be that difficult since the eyes didn't dart around, they looked one direction, paused, looked another, etc. One could keyframe the location of the flare, move forward until the eye just started to move, add another keyframe, move forward until the eye stopped again, add another keyframe, etc. Each frame wouldn't have to be done, just the beginning and ends of each eye movement, with a few keyframes in between on occasion if they were warranted.
In other words, Mocha was a big help but in this case it wasn't totally necessary. You could do it with just After Effects (or Final Cut Pro, I'm sure).
One other thing I did and forgot to mention, when the eyes looked directly at the camera, I keyframed an increase in intensity of the flare at that point so it was brighter when the eyes were in that position.
If I remember to do it when I get home, I'll upload another version of it without the flare, only a change in eye color and luminance that could have been done manually but was much easier using Mocha AE. |

thanks for your detailed explanation :)
interesting ..
(here - in written text - it all looks so clear, logic, ´obvious´ and ´simple´, lol :)
... or - maybe - it´s just your talent for explaining things clearly .. ) |
