Remove noise from only part of a clip? mask?

Your best bet is After Effects because you’ll need more advanced masking techniques like luma (brightness) masking.

Also, your video is password protected and I see no password in your post 😛

i recently was working on footage that had huge problems with grain – HUGE
after all i learned i suggest you to get plugin called neat video
it will fix the grain you are having on the wall

its a really good one, and will fix it easily – just sample the noisy region and will fix it – i dont think that there is gonna be a need to isolate the wall because of the way the plugin works

Hi, yes, I used neat video on the clip yet I am still experiencing problems in that particular area.

[Jovan Strel]

let me think —

i seems to me that this shot went through color correction process, so if there a chance that you have the original footage try adding the neat video effect to the original footage before color correction and after

also this footage seems to be of good quality, maybe 12 bit image or 16 so check to see if any 8 bit effects has been used on footage

i’ve seen simmilar problems before – the actual problem is not the noise but the color values that are getting clipped because of the way the effects are combined >>> if so reposition the effect layering

and if that fails to – what i would do if im in a time crunch –
is roto out the base of hair (remove the hair strands) and just replace the back wall
it a good thing she kinda static in that shot

getting a luma key out of this :/ — hmmm
yes the strands of hair are brightly lit but the color is simmilar to the wall color
i think roto would be quicker and then replace the wall image with a still frame

if it is a longer shot or gets more complex, then go for the luma key
differentiate the midtone values with brightnes/contrast and levels effect until you get a varyation of gray colors where the strand of hair are close to white and the wall is closer to black and then replace the wall with a still image

Yeah I applied neat video before color and then used colorista 2 and 3 way color corrector in premiere which I believe are above 8 bit. This is 16 bit footage. Not sure what’s going on here. I might just go with that roto idea unless anyone has another??
