Question

Logic and 23.976fps for HD video production

Why doesn't Logic Pro recognize 23.976fps. you can set the timecode frame rate manually in the synchronization preferences and uncheck auto recognize incoming frame rate. but if checked, Logic recognizes 23.976fps as 24fps. Is this because Midi Time Code does not support 23.976? (or does it?) I use a Motu 828mkII firewire interface that has smpte timecode input that Logic recognizes. Logic seems to recognize all other incoming frame rates (29.97 non drop, 29.97 drop,25,30 non drop, 30 drop) but recognizes incoming 23.976fps as 24fps. this becomes a serious problem in the field when multitrack audio capturing while chasing timecode provided by video production trucks or bays. for HD video production, 23.976fps is happening more and more. does anyone have a solution? can Logic read any other timecode formats besides MTC?

Logic 9 has added 23.976 as a frame rate choice. Good luck.

yes. Logic does have a 23.976fps setting in the synchronization preferences. this works fine as a setting when working with transfered OMF sessions or transfered sessions from Final Cut as an internal session frame rate. but Logic will not chase external 23.976fps because Logic's external timing is based on Midi Time Code which does not support 23.976fps. If you feed Logic 23.976fps from an external timecode generator, it auto detects it as 24fps. so when capturing audio chasing 23.976fps the files are all timecode stamped incorrectly and are not running at video speed. Apple really needs to address this issue since they are on the forefront when dealing with HD video production with Final Cut and since Logic is their flagship audio software they need to figure this out. can anyone explain to me that I'm wrong because I'm thinking about switching to some other software that doesn't depend on MTC for external sync.

any suggestions please.
