Ambassadors of Death

As reported in Wired magazine the restoration of Ambassadors of Death has gotten a boost due to a new editing computer. 

"Their method is a refined version of that trialled on the 2009 Planet of the Daleks re-release; it is now being deployed on a seven-part 1970 Jon Pertwee adventure, The Ambassadors of Death. "It seemed almost recordings, they didn't filter off the colour carrier [encoded as a 'chroma dot' pattern in each frame], which for the last few decades has been nothing more than an annoyance." Team member Richard Russell used the signal to reverse-engineer raw colour pictures that could be retouched frame by frame. "It's very, very labour intensive -- several hundred man hours' work every episode," says Steve Roberts. Luckily, a new "quadrant editor" is helping them to produce better source material upfront, so they hope to deliver the Ambassadors episodes to the BBC within weeks."
