That’s really nicely done! Did you use the behind-the-scenes footage (and add the hologram & scanlines effects), or did you use the existing hologram footage? Either way, you’ve done some great rotoscoping there! Was it a case of doing some refined rotoscoping, or did you use another method for isolating the footage?
I just adjusted the color till the blue Channel was isolated… that’s it. Some general masking wrapped it up nicely.
