sky replacement
on Nov 21, 2016 at 10:15:03 pm


I'm Trying to replace sky with some clouds,but bride is in the scene,and i tried every way to do it,but unsuccessful,
there is a question,

how can i replace sky with a huge white subject in the shot?

sky is white and bride dress is also white.and when i put cloud footage it covers sky and bride dress.

if the sky and dress have exact luma and chroma, then not even a key will work.

i made a template that will procedurally key stuff.

if it fails, i recommend looking up rotobrush for AE

hi guys,
this is what i mean,the bride in a super bright background,
by the way tanx Chris im reading that article you send.but i have a big problem with luma and chroma.
there should be a way to isolate back Scene and for Scene.

I don't even think the rotobrush will help you here. The veil on her head and sky are blown out. Not sure if you tried color correcting to see if you could get any additional info back, but I think it is probably too over exposed. You could try to manually rotoscope, but the computer can't differentiate the veil and sky and I'd be surprised if you could while going frame by frame.

There's no way to isolate the foreground and background when both are essentially pure white.
