VFR (variable frame rate) time code
• At 24PN, recording is performed at 24 frames and output uses a 2:3 pull-down scheme to produce 30 frames.
• At a frame rate (capture frame rate) of 24P the speed of recording and the output time code matches actual time, but not
at any speed other than 24P. (Example: at 60P recording progresses at 60/24 speed)
• Then the camera operates in Rec Run mode and the time code output at start of recording matches the recording time
code.
• This is true also for frame rates other than 30P capture in 30PN mode
