Memo :
Drop frame/non-drop frame mode
● When the frame rate setting in [Main Menu] B
[Record Set] B [Record Format] B [Frame & Bit Rate] is
60 (30), the actual number of frames per second is
approximately 59.94 (29.97). However, the time code
processing standard is 60 (30) frames. To make up for the
frame number discrepancy, the drop frame mode (Drop)
drops the 00 frame and 01 frame every minute except for
minutes that are multiples of 10.
● On the other hand, the non-drop frame mode (Non Drop)
does not drop frames and ignores the discrepancy with
the actual time.
