I have a collection of old (40+years) family super 8 films, most are on the original 75mm reels. Should these still be okay to view on a projector? I also have quite a few larger reels of film, from memory these are all spliced together from the original shorter 75mm reels. I understand the spliced reels are more likely to break at the joins, but will the age of the film itself pose a problem? Would i be better off to have them professionally converted to digital? I'd love to sit down, with projector and screen and watch them the way my Mum and Dad used to show them. thanks in advance!!
