Doctor Who (1963) Season 8 Episode 21

By 1978, the BBC had wiped the colour videotape masters of all but Episode Four, although monochrome film recordings made for export survived for all episodes.

In that year, Ian Levine asked a friend to record the programme from a broadcast by KCET TV in Los Angeles, U.S.A. using a Betamax VCR.

In 1992, the serial was recoloured in a complex process involving the combination of the colour signal from copies of these tapes (and another fan recording, used to bridge a gap when tapes were changed during brodcast) with the luminance signal from the monochrome film recordings. For a full account of the restoration, see the Restoration Team Website.

This recoloured version was first broadcast on BBC 2 between 20 November and 18 December 1992.
