I just finished a lighting fix I needed to do for an interview shot by someone else. It went okay, but I feel I could have had more control. I'll explain.
Instead of just having spot lights where you adjust the cone, etc., I'd rather see a more accurate simulation of how film and video lighting is done on a real set. First of all, if you're trying to fix a video that's already been shot, even if you convert that layer to 3D, it's still going to appear in 3D space as a flat plane, so you can't do things like backlighting, etc. And if you're fixing lighting, or trying to do something creative with lighting, you need to be able to light objects separately within the frame. WHAT IF Adobe could use AI to automatically detect and separate all the individual objects in a flat video, then the user could drag each object along a Z axis to determine how far apart those objects were? Then you could pick virtual lights according to commonly used lights (e.g., a Fresnel, a par, a softlight, etc., each with their unique lighting characteristics), and choose your lighting modifier, whether 1/4-stop, 1/2-stop, or full stop softbank or scrim, and add in flags of whatever standard size (18x24", 24x36", 48x48", etc.) to block light from spilling in certain areas. Maybe have the ability to attach virtual barn doors to the light fixture and adjust them. We'd have a lot more control with lighting that way. Or does an existing third party plugin already do what I'm describing here?
