 Setting the Time Code
368
If the frame rate is set to 2 (119.9 fps), 8(59.94 fps), or 6(29.97 
fps), the time code’s frame count causes a discrepancy between the 
actual time and time code. When [Enable] is set, this discrepancy is 
corrected automatically. This correction function is called “drop frame.” 
This is for advanced users editing movies.
Enable : The discrepancy is corrected automatically by skipping time 
code numbers (DF: Drop frame).
Disable : The discrepancy is not corrected (NDF: Non-drop frame).
The time code will be displayed as follows:
Enable (DF)
:  00:00:00. (Playback time: 00:00:00.00)
Disable (NDF) :  00:00:00: (Playback time: 00:00:00:00)
Drop Frame
If the frame rate is 3(100.0 fps), 7(50.00 fps), 5(25.00 fps), 
B
(24.00 fps), or 4(23.98 fps), the drop frame will not work. (If 3/
7
/5/B/4 is set or if [53: Video system] is set to [For PAL], 
[Drop frame] will not be displayed.)
