I was reading the contents of the hacks (in the 'setj') and was wondering, whether anyone believes, that Vitaly or anyone else, for that matter, would also be able to make 23.976 frames into exact 24 frames. It would help with the workflow.

In FCPx I think it has this option.. I believe I did it before

FCP X doesn't allow you to simply flag 23,976 as 24. This would just tell the player that one second now equals 24 full frames, so that the speed would be a little bit higher.

FCP X only can convert frame rates by maintaining the exact duration of the original timecode, either by doubling roughly one frame every minute (resulting in a short jump) or using the very time-consuming process of optical flow.

The first question is, why you would wish to change 23,978 to 24. In Pal countries, if you had 25p, you made video NTSC-compatible by changing the frame rate to 24p (duration is 4% longer, audio pitch is a semitone lower). Movies were sped up to 25p (4% shorter, pitch higher).

With old FC-Studios Cinema Tools, you could batch-convert your (intraframed) clips with just one click. In Premiere, you can interpret the footages frame rate, with Vegas you can use a script or something.

For FCP X, you can use 5D2RGB, because during conversion, the frame rate can be changed.

Practical advise: If you desperately need 24p, edit your film in 23,978 and export it as such. Take the master and convert it, using one of the methods above. For a 90 minute feature, the difference in duration is 118 frames, not even 5 seconds. Unnoticable.

"24p" is just shorthand for 23.976 frames per second, non-interlaced - nobody actually shoots at 24 frames per second exactly (unless shooting real genuine film!) So if your project is "24p" and that's what your camera shoots, leave the frame rate alone.

If you have footage from a camera that ran at a different frame rate, then you can of course convert that to 23.976.

This odd frame rate is used for historical reasons, to avoid flicker when films were converted to video for transmission in the early days of TV.

Thanks everyone, for the replies.
Am replying late, cause I usually, just read the topics, and replies, and I seemed to have lost sight, of the fact, that I posted this query.
Thanks again
