6.5.5 Frame Counter
It is recommended to check the requirements of
all facilities involved in post-production prior to
shooting.
Very often the camera is set to run at a different speed than
the video system. In areas with NTSC video system for ex-
ample, the film camera would run at 24 fps whereas the
video system works with 30 full video frames per second.
In order to adapt to specific needs there are two different
time code formats possible.
To relate the time code count to the film camera, select the
mode FRAME COUNTER FILM, which is often
referred to as ”film-related time code”. In this mode, the
frame counter of the time code (the last two digits of the
time code display) is increased by 1 if the film is advanced
by one frame e.g. 24 times a second at 24 fps. This makes
it easy to identify one particular film frame by looking at the
video image. However, this mode will create an unusual
time code count because some video images are repeated
to cope with the different frame rates of the video and the
film camera. These repeated images will get duplicated
time code words, which will create error messages on
some time code readers.
To relate the time code count to the video system, select the
mode FRAME COUNTER VIDEO. This is often re-
ferred to as ”video-related time code” . Every full video frame
will ad-vance the time code by 1 e.g. 25 times a second in
PAL or 30 times a second in NTSC. The IVS now creates a
standard time code. However, it is more difficult to get the
link back to the time code, which was recorded on film.
To get a reliable relation, it is necessary to utilize the Pull-
Down (refer to chapter 6.8) or White-Line-Flag information
(refer to chapter 6.11).
At every full second, both time counts are identical.
