Filmed inserts into regional news added a significant delay to the airing of programmes. STV, having no film processing capability of its own at Cowcaddens, sub-contracted this to a specialist company – Humphries Film Laboratories. Exposed film would be rushed to an industrial unit in North Glasgow to be processed and returned to Cowcaddens for the 16 mm film to be edited and prepared for transmission. This process often caused much annoyance to reporters and crews alike, as to ensure inclusion of a breaking news story for "Scotland Today", film had to reach the labs no later than 4.30 pm. By the early to mid-1980s, STV had followed the rest of the ITV network in dispensing with film and embracing electronic news gathering, with Sony's Betacam being the chosen system.
