JCC Posted September 22, 2013 Report Share Posted September 22, 2013 I googled this a lot but have not found a definitive answer: If you shoot PAL 24p on 5D mark3 and NTFS 24(23.98) on any other hd cam, and both are exact same start/stop times and exact same audio/footage- will there be any difference? My 5D mark3 has PAL and NTFS system settings, and they both offer 24p- is there a difference? What's the difference between PAL 24p and NTFS 24p? I understand PAL is 50hz and NTFS is 60hz, And I get that PAL likes 25fps because it is easily divisible into 50, and NTFS likes 30, or 23.976 with a pull-down because that can be divided into 60. But 24 into 50? Are the base times (50, 60) no longer an issue in HD? If there is no difference, will PAL 24p cut seamlessly with any other NTFS 24p?

David Levine Posted September 22, 2013 Report Share Posted September 22, 2013 The NTSC camera will produce a clip with .01% fewer frames that takes the same amount of time to playback. Quote Link to comment Share on other sites More sharing options...
studiomprd Posted September 23, 2013 Report Share Posted September 23, 2013 " NTFS system settings " ?? " The NTSC camera will produce a clip with .01% fewer frames that takes the same amount of time to playback " I've never seen it put that way...and that is incorrect! PAL is a system of encoding color onto video signals, and NTSC is a different method of doing that, but it requires a non-integer frame rate, that is a frame rate .1% slower than integer rates. thus it takes longer than 1 exact second to complete the companion integer frame rate number of frames... (example at 29.97 FPS, the 30th frame is completed, but it extends beyond one second of time.) Quote Link to comment Share on other sites More sharing options...
Patrick Tresch Posted September 23, 2013 Report Share Posted September 23, 2013 From what I know. 24p is on todays Firmwares actually 23,97. REAL 24p has been killed on the 5D a few years/monthes ago. But It could be that 24p "pal" is real 24p as we (PALpeople) don't use fractions (0.03) for color sampling. And 24p NTSC could be 23.79 to be in pair with the color sampling of NTSC countries.... ? You can shoot a test of both settings and make a commande+i on the file to see what it tells you.

tomlowe Posted October 16, 2013 Report Share Posted October 16, 2013 NTFS is a drive format - NTSC is a video system. It is probably that in PAL mode you get 24 fps and in NTSC mode you'll get 23.976 fps which is easier to convert to 29.97fps with a 2:3 pull-down.

John Blankenship Posted October 17, 2013 Report Share Posted October 17, 2013 People who wish to understand this stuff should ignore everything in this thread -- too much incorrect and (perhaps even worse), almost-correct, information.

Wandering Ear Posted October 17, 2013 Report Share Posted October 17, 2013 RTFM is in order here. This is a question specifically about the 5d settings, and guess where the correct answer actually is? Quote Link to comment Share on other sites More sharing options...
