Drop frame mode
SMPTE time code runs at 30 frames/second, while the NTSC color
television system runs at about 29.97 frames/second. This means that a
length of 1 hour as indicated by time code is longer than the actual clock
time of 1 hour by 108 frames, or about 3.6 seconds. Drop frame mode
adjusts the running of time code to eliminate this discrepancy by
dropping two frames from the time code value at the beginning of each
minute except every tenth minute. In contrast, non-drop frame mode
does not adjust the discrepancy between time code value and actual time.

E-E mode
Electric-to-Electric mode. When you operate a VTR in E-E mode, input
video and/or audio signals pass through electric circuits only and then
come out from the output connectors, without passing through
A
electromagnetic conversion circuits such as recording heads. You can
use E-E mode to directly check and monitor the input signals without
recording them on tape.
