Math Operations
For basic decimal math operations, see
the beginning of this guide. For real-
time, video time code and film math
calculations and conversions, the follow-
ing rules apply:
(1) You can add, subtract, or divide be-
tween all formats.
(2) You can multiply a formatted value
by a unit-less number.
(3) Conversions between film and NTSC
time code are based on 3:2 Pull-
Down at a ratio of 24:30 and adjusted
for 0.1% speed difference if refer-
enced to 59.94 Hz. The 30 DF to 30
NDF conversions are based on frame-
to-frame matching .
(4) Some math operations or conver-
sions may result in remaining frames.
Press [Conv] [÷] to see remaining
frames.
(5) Non-existent Drop-Frame time code
values (for example, 0:01:00:00 and
0:01:00:01) will roll down (to
0:00:59:28 and 0:00:59:29), not up,
when entered.
