To the best of my knowledge, Toy Story has never been presented in 60 fps - only 24. The DVDs and Blu-rays are all at that same frame rate, so an ISO rip of whatever you plan to use for this project would be 24 (or technically 23.976) frames per second.
well, i’ll see what i’ll do. maybe it was only the trailers that were 60 fps? can’t seem to remember.
