My Attempt to Fix it in post! Rolling Lines on the screen! Color distortion! HEEEEELP
Hello Creative Genius!
I received footage from my shooter yesterday and have been charged with the duty of “fixing it in post.” Unfortunately we have already told the client that this can be fixed so I am now forced to pull the bunny out of the hat and try to get it done!
PROBLEM:
The interview as seen below has long pink bars that roll up on the screen slowly. The footage was shot in 1920 x 1080 29.97

WHAT I THINK THE PROBLEM MIGHT BE:
I think that the shutter speed might have been set incorrectly and the rolling lines are a reflection from the LED lights.TOOLS I CAN USE:
After Effects
Premiere Pro
Photoshop
Hell anything at this point!ANY SUGGESTIONS ARE WELCOME~
Thank You Super Hero!

This will be a long, expensive, tedious, but doable, job.
If it were me – AE: colour-correct (whatever you need, curves, HSL, exposure, multiple times and multiple layers/mattes) the purplish areas to match the rest and then use a feathered mask to match the areas as much as possible. Then you’re going to have to keyframe the movements.
This is what 5 minutes did (it’s not even close to good enough – but with enough time and effort you can get there):

I was afraid of that..
Do you think motion tracking may be in order as well?
It does look better.
Could you email me your AE project so I can begin to try and replicate what you did? asia.taylor0@gmail.com
Thank you so much for taking the time out and doing this..

Hi Asia,
I didn’t save it. But the gist of it is:
1) Duplicate the layer
2) Create a mask over an area you want to fix on the new layer so you only colour-correct the area you want to fix (like a grading mask or power-window)
3) Colour-correct as required with the appropriate tools (ones you’re familiar with)
4) Feather the mask/expand the mask appropriately to match/disguise
5) Keyframe the mask so that it moves with the discoloured areas (motion tracking will be difficult since what you would need to track isn’t an easily delineated point or set of points). This movement should be fairly consistent/cyclical, so realistically you’d only have to do it once from out of frame (top or bottom) to out of frame and then copy/paste as required.Good luck!

Oh, you may want to ask in the AE forum too – there might be others with more experience/better suggestions than my own.

It looks like fluorescent light phasing to me. Are you in NTSC land? Maybe the camera was set to 50fps or something.
Fixing will be hard. I’d try mitigation first. The lines are most visible over the grey background. I’d try keying the grey and desaturating.
