When talent forgets to bring flesh coloured underwear and refuses to go naked (to be honest I don’t blame him it was a very crowded and cold set) it’s up to the VFX team to fix things.
Luckily for me the advert was shot in 4K on my RED Scarlet. More pixels means you have more information for tracking, rotoscoping or creating skin coloured patch to cover tightie whities.
Taking a single frame of 4K footage into photoshop I painted out the underwear. The skin patch was then tracked using After Effects CC onto the model so it stayed in place during the dolly move. There was little hand tracking to be done to the shape of the mask to keep to compensate for the perspective shift as the camera pushed in.
The next shot required the artist to hold a paint brush up in front of her subject as (if measuring him for her drawing) The problem with the original shot was the white underwear created a big blurry white blob around the models crotch which ruined the ‘mike myers’ gag of teasing the audience that you are just about to see something rude until it’s hidden by a potted plant.
Using another 4K still from RED footage I rotoscoped the models hand holding a paint brush, added some animation to keep it alive and then comped the whole thing in After Effects using a 3D camera to add realistic motion blur and depth of field. After some tricky colouring to match the still foreground hand with the raw RED background footage the gag is complete.
