The Scene Sync Story (documentary)
From Tardis Wiki, the free Doctor Who reference
The Scene Sync Story (documentary) was a documentary that explained the technology of Scene Sync, a motion control process for improving the composition of shots involving CSO. It interviewed two camera operators, Peter Leverick and Roger Bunce, along with visual effects designer, Stephen Drewett.
It was included on the Meglos DVD, since Meglos was the only Doctor Who serial to use Scene Sync.
Though narrated, the narrator wasn't credited.
