59.94 VS 60 HZ SETTING
what is the difference between the 59.94 and the 60 hz setting? I have read the manual about the frequency settings but all it had to say was that “this unit allows the frame frequency to be switched to 60 or 59.94 to provide support in areas with different video systems”. What does that mean?
is it true that the varicam always records to tape at 29.97, no matter what frame setting you are using?
i just shot with the varicam using the following settings:
24P
59.94 frequency
film rec modeis this a correct setup for shooting 24P footage?
thanks,

Jamie,
The Varicam F and H models have the capability of switching the systems frequency from 59.94 to 60 Hz. The main function for this is so that the camera can create a true 25p or 50p speed for use in PAL countries. Another obscure rational is to create an exact 24fps rate as opposed to 23.97 for use in intercutting with film footage that will only be projected, not telecined; and this is rarely if ever done.
The settings you used are correct; 24fps at 59.94 yields a tape exactly like you would receive from telecine of film shot at 24fps and transfered to tape for use in postproduction and exhibition on television. even if the project eventually goes to “film out” and is converted back to 24fps film, the slight correction from 23.97 to 24 is made to the picture and sound at that point.
Hope this helps!

Jamie,
If you shot at 60 hz then imported to NLE the sound would be out of sync because all audio in NTSC domain is 59.94, while the picture would be longer. Believe me, the one and only reason to use the 60 hz setting is to shoot for PAL broadcast at 25 or 50 frame rates!
