6.3.2. 3:2 Pulldown Processing

When using a 1080i/59.94 input video feed containing 3:2 pulldown, the 7711HDC must be operated in
Field Mode in order to minimize motion artifacts. In Field mode each field of the incoming image will be
downconverted to one field of output image, so there will be no pulldown related de-interlacing artifacts on
film originated material with 3:2 pulldown, or video originated material acquired at a nominal 24 frames per
second.
When using a 720p/59.94 input video feed the 7711HDC will operate in Frame Mode where each frame of
the incoming image will be downconverted to one field of output image, so there will be no pulldown
related artifacts on film originated material with 3:2 pulldown, or video originated material acquired at a
nominal 24 frames per second.
When using a 1080p/23.98sF input video feed the 7711HDC operates in Frame Mode where each
segment of the incoming image is combined back to a progressive frame before down conversion. After
down conversion, extra fields are inserted to create a 3:2 pulldown at the output. The Pulldown Reference
menu is used to determine the cadence of the 3:2 output.

With this control, you can set the input and output video
standards.
Note: When set to Auto, the module cannot distinguish between
1080i/59.94 and 1080p/29.97sF, so it will be treated as
1080i/59.94. Similarly 1080p/25sF will be treated as 1080i/50.
