VFR (variable frame rate) time code
• In 24PN mode, recording is performed at 24-frame time code, and output is performed at 30-frame time code to match
the 2:3 pull-down scheme used for video output.
•
At a frame rate (capture frame rate) of 24P in 24PN mode, 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 and 25P capture in 25PN mode.
