Hello, if I understand correctly you need to achieve HDRI video effect when nothing is overexposed, like windows, sky...that's perfectly possible, but it's very hard to judge if I do not see actual footage. I have done extensive rotoscoping jobs, you can see example in my portfolio. I also has done green screen BG replacement, 2D tracking with Mocha / After Effects
judging by description, this project requires Rotoscoping, 2D Tracking, maybe some Keying as well.
I have installed mobile app and I am available all time, please let me know more details if you are interested in my offer and if you could share some actual footage that would clarify all doubt how task will be solved.
cheers
