## Difficulty
Hard. (?)
## How To Solve
Extract all the frames from the video (e.g. using ffmpeg: `ffmpeg -i RedLightGreenLight.mp4 frame%04d.jpg -hide_banner`).
Each "light" appears X frames, the number of frames form a decimal number. Convert the sequence of decimal numbers to ASCII to get the flag.
