We are shooting on Red MX for theater release 24fps but when we see our footage on Redcine X pro the meta data shows 24fps but bottom left in the viewer shows 23.98 fps.How does this effect our workflow as we want our final film at 24fps.
It shouldn't be a problem until you get to the DCP stage (I assume the theatre release will be a DCP). Most DCPs have to be created at 24fps although the project can play them back at different speeds if needed.
I was recently working on a project that was shot, edited, graded and sound mixed at 23.98fps. The only additional step that was required to make the DCP was that I had to throw the audio stems from the mix back through Pro Tools and alter the speed so that the audio was the length that the DCP creator would be expecting (basically speeding up the audio to play at just over 100.1% speed).
It worked like charm and in total added just under 3 hours to the post production process for a 2hr film.
once you have your 24fps DCP the cinema projector should be able to play it back at almost any frame rate you suggest but if it is played back at 24fps there will be no noticeable pitch shift or effects apart from the running about 7 seconds shorter than expected.
