Any way to remove hair flyaways?

PostFri Jul 29, 2022 6:13 pm

My client doesn't like how her hair looks in the video clip. Is there any way to track it and remove them?

I'm always astonished at people who don't want to invest in good hair and makeup on the set, and then complain about wanting fixes in post. That lady has shiny cheeks, a shiny forehead, and neck wrinkles -- and all those we can fix (to a point), but flyaway hair... I'd tell them it wouldn't be effective to try to do it in final color, but I'd send it out to a couple of VFX people to get an estimate. Usually the number is high enough that they balk and let it go.

She talked about getting a hair and makeup person but ended up not getting one.
It's so easy to fix a still image in Photoshop but I didn't think it was easy in Davinci Resolve.
Thanks for your confirmation.

Half-joke answer:

1) Make a clean plate
2) Use the AI Tools in Resolve 18 to automask her face.
3) Comp her back over the clean plate and let the looseness of the AI roto do its "magic" and cut off any fine detail hairs outside of her main hair. :D

I think if you were to try that, the problem is that you'd get moments where occasionally the hairs would appear and disappear, and I don't think "AI" tracking or anything like that could fix it. It'd be even worse if this is a 20-30-minute interview or something. If the segments were really short, maybe you could could chase the loose hairs and comp them out or at least blur them or something. But it'd be potentially thousands of dollars of VFX work (assuming 2-3 days to do).

If you did a temporal blend and she didn't jerk her head around too much it should be a pretty soft artifact.
