frame is easier to locate than the viewing screen’s frame. The director
can then immediatly control his operator’s images.
Of course, the video assist was first created to be used in such a way.
But, now that video editing (including the virtual video editing)
offers new powerfull tools to the editor, the CD56 can be used in a
different way. The CD56 provides a Vitc lines generator, which are
the dots and lines, usually put above the video image, used by video
editing machines. Therefore, images recorded by the video assist
may be directly used to make a video editing of the film; no need to
wait for telecine, no need also to have developped the rushes you
won’t use.
2.11.2 Installing the Control Unit
All of the CCD assists available for the AATON 35-III can be easily
attached on the camera body, in a few seconds without the need for
adjustment.

motor side of the camera. Using a Allen wrench, loosen 3 or 4 turns

The CD56, as well as the

Vitc lines
•
First line is the video timeco-
de line. Each time you switch
on the video assist, the video
timecode is set to 1:00'00'' 00
(the last number is the image
number). Then as soon as the
AATON 35-III is running this
time is incremented.
•
Second line is the keycode
line. As the keycode should be
read from the film, this line
cannot be generated. Only syn-
chonization and checksum bits
are inserted.
•
Third line is the audio time-
code line, i.e. all the timecode
information of the AatonCode
is inserted here.
