I watched the first episode out of curiosity. Does anyone know why there is a mix of film recording for some of the location filming, and then video for other parts that are shot on location?

TBH there's quite a lot of that in shows from the 60s-80s, probably based on what was most practical/available at the time of filming. After all, video location work at the time would have needed big cameras and an OB unit which wouldn't always have been available or practical.

From what I've seen of Emmerdale Farm, the first few years are a mix of film and video on location, though heavily biased towards film in 73/74. I haven't seen any post-1975 filmed location work on Emmerdale Farm, though it doesn't mean there wasn't any.

Compared to Corrie which was still using film until 1988! Though funnily enough Corrie had a lot of VT location work in the 60s and early 70s, though it seemed to drift mostly to film after around 1976 and video location work seemed to have gone entirely by the start of the 80s. Certainly with the episodes we saw on ITV3, the only 86/87 video location work was the fire episode, then a couple of brief scenes a couple of weeks later with Jack Duckwork trying to get people to join the Graffiti Club. Then there were 4 weeks in December 87/January 88 where all the location work was video, then it was back on film for another 5 weeks, before going video full time in Feb 88.

It just seemed quite unusual to see the mix in the same episode, especially when some scenes seem to be the same location. But like you say, probably due to equipment availability on different days of filming.
