Couple of questions, is there an IRC channel already established for Fusion?
I have green spills that occur in some footage I am working with on the keying phase. I have been using the Ultra key tool and using the Pre-matte size, matte separation, matte contract/expand, matte blur and matt gamma to help ease the spill and have my alpha be crisp and solid.
The actress has her limbs close knit throughout most of the footage, then when she gets into her acting and start separating her limbs from body, I get spills between the crotch and arm pits.
What other techniques used to help isolate these problems and totally make the green transparent?
There are problems I saw when they took the footage such as:
Model too close to green background which causes the subject to have reflections from the green background onto the subject.
Lighting is arranged to help prevent spills to maintain the green BG to have a solid tone of green but at times, the short distance of the lights contribute the reflection of green on the actor.
Some footages have a small resolution size with pixelated information that can be hard to clean up in post production.
CU (close up) shots are great! When the actor is at a distance is when artifacting starts to take place. I dont know if this is a camera lens issue or her being closer to the green screen background.
Any suggestions on proper footages to use for post production would be great!
I thought of some solutions to these problems such as:
Having the actor be in the Da Vinci pose so I can key out the green while limbs are separate from body
if camera is stationary---have the actor not be in frame, key out the green at that time, then have actor get in frame.
Am I on the right track or are there better ways to handle these problems I am facing?
Appreciate all the sincere comments. It helps me out tremendously and I highly value experienced suggestions thats given freely.
All the best,
Cypher
