Bearing in mind that inventing extra lines is harder than taking them away and the 625 to 405 line converters that were being installed in the transmitting stations around 1967 were the size of a medium sized room. The way ITV would do it (if they had a sale to a 525 line country) was to record with two sets of cameras or use one set and switch them over to the other standard and make a new recording. They did this for example on two Ingrid Bergman plays filmed by ATV/AR Twenty Fours in a Woman's Life 1961The Human Voice 1966

I'm thinking more of a long persistence TV tube and a 525 line/60 camera pointed at it. That seems to ring a bell in my memory for converting one way or another.

Optical for sure in the early days.
