Just when you thought the impossible couldn't be done, some smart bast**d goes and does it! It also highlights the crass stupidity of the BBC, who transferred much early colour videotape in their archives to mono film, then erased the original masters. :eek: Whatever they were smoking it was powerful stuff!! Cheers Billy 8-{) :clap |

| 726922 | 2008-12-11 09:31:00 | To recover something, suggests it was there in the first place! You'd think so Ciccy, and conventional wisdom would suggest that it must, but these images are being recovered from pure black and white film with zero colour data supplied . You'd really need to read the story very carefully to see how it was done, but in essence some monochrome artifacts from the original chrominance signal were present in the background of the image and by some extraordinarily complex computer/ algorithm and mathematical process (that makes my brain do backward flips every time I try to get my head around it) they found a way to extract and process that mono information, then link it to control a colour regeneration system . I have an intimate knowledge of how the PAL Colour TV system works, I was involved in it from the very start in NZ and was sent to the UK beforehand to study it, but this just leaves me gasping .
