Hi There!
I am trying to do a sky replacement on this piece of timelapse footage: http://vimeo.com/28308019 (PW: timelapse). I am using AE CS5 & I have tried using colorama & rotobrush to mask out the sky, but they are not providing clean enough results. Anyone have any tips or tricks that would help?
Thanks!
How about a simple luma keyer with garbage matte for the lower part of the picture and the pole on the right side plus additional mattes for buses if necessary? BTW, these windows will be quite a pain to roto and composite…
Bart, your approach makes a lot of sense. I like it.
Corey, what does the replacement sky look like? Since the bus windows are tinted and don’t match the current sky you might get away without having to do major work on them. The outside bus mirrors, on the other hand, will probably be tedious.
Thanks for the help! The thing that worked the best was throwing colorama at it and raising the brightness & contrast (I did not do this the first time I tried) to completely blow out the sky and key it out.
Thanks for the help and tips!
Great! I’d love to see the final clip if possible.
