It is also possible to define an address within a video itself.
FRx
indicates a frame number within a video where FR denotes frame
and
x
refers to the frame number.
FR3000
, for example, would
refer to the frame 3000 of the current video. This equates to 100
seconds or 1 minute 40 seconds into the file. The frame number
refers to actual video frames and calculating at 30 frames per
second non drop, which is the NTSC standard, gives you the time
elapsed at this frame of video. See
Frame Number Request (?F) on
page 191 for command.
TMx
indicates a time code value using the format HHMMSSFF
within the video.
H=Hour
M=Minute
S=Second
F=Frame
For example,
TM1263212
refers to the point at 1 hour, 26
minutes, 32 seconds and 12 frames in the video. The
TM
values
will always be interpreted as a right justified value so TM 3415
would reference the position 34 seconds and 15 frames into the
video. See
Time Code Request (?T) on page 192 for command.
