I was playing around with slow mo last night within FCP. I was editing footage from my GOPro shot @ 720p 60fps. i followed this link to convert the files. I used the proress codec it suggested. Should i be using any of the others? ProRes 422maybe? When converting the files i left the settings as they were, but they were exported @ 50fps. Should i of put 60fps where it says frame rate? Are those settings correct? Anyways...when it came to editing, and dropping the speed of a clip down to say 25% it became abit jumpy. So i went to the sequence settings and then realised i wasnt using the correct preset, so i changed the preset to involve 60fps. the re-edit was abit smoother but still jumpy, is this simply because its footage from the gopro or is it me? Is there a sweet spot % to get the best slow mo? I would imagine bringing it down to something like 25% it would of needed to be shot in a higher fps? Should the settings when changing speed be different? Should it say 200% as its double the frame rate? Or is that % simply just speed of film? if someone understands where im coming from, and can shed some light in editing with 60fps...that would be very much appericated.
