The Dad's Army episode "Room at the Bottom" which previously only
existed in black & white has been restored to the original colour using
the full-gamut recovery technique which decodes colour information from
burnt in chroma dots on the Film Recording.
The restoration was
undertaken by the Colour Recovery Working Group & Richard Russell
who developed the process from work by James Insell, and wrote the
software used for processing.
The 'raw output' of the recovery process has been restored and VidFIREd
by Peter Crocker at SVS and was graded by Jonathan Wood. Mark Ayres
restored the sound which typical of optical film had various crackles
and pops, so the midlands radio and tv recordist who recently returned
'A Stripe for Frazer' has provided the soundtrack from his off-air
recording. The restoration was overseen by Ralph Montagu.
Room at the Bottom will be broadcast in Colour, for the first time in
almost 40 years on BBC2, Saturday 13th December 2008
