6.3.5. Support For Telecine Devices That Do Not Have A Frame Pulse
Available.
In order to accurately track the 3/2 pulldown in 24 FPS NTSC transfers,
and to track the field dominance of 30 FPS NTSC and 25 FPS PAL
transfers, the 4025 requires a 'frame pulse' signal. Some 'flatbed type'
telecine devices that use a rotating prism combined with a video camera do
not provide a frame pulse output.
To enable the 'no frame pulse operation' of the 4025, set DIP Switch # 7 on
the 615 card (center module) to the On position. The Frame LED on the
4025 front panel will be ON all the time.
Do not use AUTO rate detect when you have DIP Switch # 7 turned ON.
Select the correct film transfer rate that you are using.
The following limitations apply when operating the 4025 without a frame
pulse from the telecine.
The field dominance for 30 FPS NTSC and 25 FPS PAL transfers is
assumed to be field 1.
beginning of field 1 of a video frame.
The pulldown for 24 FPS NTSC transfers will be random. As there is
usually no real pulldown of the picture, but rather a blending of pictures as
