Working on a short film, shot on Super 16mm. Well I just have a humble converted K-3, so the frame rate is not exactly 'accurate'. Sound will all be added in post. But I wonder why all labs here in Europe have a default film scanning frame rate of 25 fps and in the US it is 24 fps. Especially since all cameras I know of meant for screening (as opposed to European TV) always have a frame rate of 24fps, including the old Super 8mm sound cameras.
I know that 25fps comes from the old PAL television standard (50 fields per second, 25 frames - all movies shot at 24 fps ran slightly faster to be in sync with the TV standard).
I would like to choose a frame rate which is the most compatible with HD 1080p. No planning on getting my humble movie projected theatrically, but I would like to have it as compatible as possible with existing (and if possible future) standards. Also: if I work at 25fps and it will be played back at 24fps or vice-versa (not sure about the digital tech details though), the sound will be altered. At the very least its speed and probably also the pitch, as was the case back in the analog days - which is bad especially for music. Any tune recorded at 24fps and played back at 25fps is almost a half step higher and the tempo is faster (I am a pro musician and I checked it many times). I would love to work at 24fps, simply because it's the cinema standard. My main concerns are compatibility and sound. The look of 24fps vs 25fps is virtually indistinguishable (IMHO) on modern screens and monitors.
Any input, insight and tips highly appreciated.
Thanks in advance,
