I’ve been doing something similar using “cheap” Chinese band notch filters. Had no idea about this Disney process. Also using this for AI training purposes. It’s amazing what you can buy on Alibaba, fully custom frequencies.
- krasin 3y agoI would be interested in some links!
- sixothree 3y agoAfter you using sodium vapor out a different light source?
- jmpman 3y agoDifferent frequency.
- p_noumenon 3y agoAny thoughts on whether some frequencies are superior to others for various reasons, or what strengths/weaknesses different frequencies have?
- jmpman 3y agoThe frequencies I’m using are very specific to the subject I’m filming. It’s closer to a machine vision problem, and it isolates the desired object almost perfectly from the background. I’ve considered filing for a patent, it works that well.

- speps 3y agoIt's explained in the video. Keying algorithms are getting better thanks to AI image techniques. However the training data they use is based on green screen technique so has the same issues at times. Using the sodium vapor method to film training data that looks correct to start with would improve these AI algorithms.
- fnands 3y agoVery cool!
