not sure how to junk matte this
i have my footage of two guys on green screen. the guy in the back is supposed to be naked, as mentioned in my previous post. the guy that needs to be naked is wearing nothing but rolled up black shorts. i got some suggestions on creating a junk matte for the shorts but not real sure how to do that. the only other option was to mask the footage with a solid that matches the skin and keyframe the solid, which will kinda look nasty. this is kinda a timely project and what i need to know is can i still get this effect and how i go about doing it, or am i just better of filming over again with the actor wearing whitie tighties or something? thanks to everyone that responded to my previous post.

If someone suggested junk masking the shorts, what they probably meant is to place a comp size solid roughly matching the skin tone behind the footage layer, then make a mask on the footage that covers the shorts. Then keyframe the mask so it roughly sticks onto the shorts before precomping the lot and applying the mosaic effect. Obviously the longer the shot, the longer this will take, so you’ll have to decide yourself whether it’s worth starting from scratch.

yeah it’s sort of a long shot, so i’ll have to keyframe it, but i think the advice you gave me is working for what i need it to do. thanks alot!

The reason I wrote before that this shot will be difficult is because it’s not a junk matte you’ll need, but rather a cloned section of skin that will have to be hand tracked frame by frame to match the actor’s motion. It will have to blend smoothly with the surrounding skin and match any shadows cast onto the actor. Its edges may need to be rotoscoped, and it may need orientation adjustments in 3d space if the actor rotates.
Shooting with tighty whiteys would give you the same problems.
Just shoot the dang guy nude. Or devise a little cut-out cardboard circle that he can sort of tie on, if you get my drift. That will then serve as a good tracking marker for the pixelated cover-up gag you want to do.Joey Foreman

yeah, thanks for the input. i will keep this in mind if i ever have to do it again. i saw exactly what you meant by how hard it would be by having to create a shape and keyframe it every frame. it was a real pain. i tried to make it look as best as possible or what visually looked right. thanks again!!
