I'll do this and let you know how it goes, I don't think I can easily add colour but I can work some other magic. ETA is likely 2-3 hours + whatever it takes to upload (assuming I get back to it tonight - otherwise I’ll upload tomorrow morning).
I think I can do better though, so will try another method in the morning.
It’s quite hard with such low quality footage. I think could be done is use some sort of algorithm to stop that sort of wavy chemical look that might be beyond me anyway that video did clean up a bit!
