The HD-IVS can generate information on whether the current video image
corresponds to a new film frame or whether it is a repeated video image.
The Pull-Down information displays that in manually readable form.
The HD-Link speed of the HD-IVS can be set to one of the following five
speeds: 23.976, 24, 25, 29.97 and 30 FPS. The ARRICAM ST can run
anywhere between 1 and 60 FPS. Sometimes it is necessary to use a
different HD-Link speed than the standard 24 FPS frame rate of a film
camera, e.g. because of recording or post production requirements. In that
case the HD-IVS has to deal with the different frame rates. This is achieved
with a frame store, which alternatively either adds additional video
images or drops images . The Pull-Down information provides information
on the duplicated video images.
In practice, the most important case is a film camera speed of 24 FPS and
an HD-Link speed off 30 FPS.
