Select SF Mode
The Kayak HD system supports 1080sf (segmented frame) video formats at
23.9, 24, 25 and 30 fps. Segmented frame video captures a frame of video
progressively, but displays the frame as two interlaced fields.
This can give a slightly different look to the resulting video playback. Inter-
laced and segmented frame video requires different internal system video
processing techniques. These include changes to crosspoint cut points,
wipe pattern geometry, and interpolation.
When using Auto Detect the Kayak system automatically detects the line and
frame rate of the incoming video reference signal and reports its sync refer
-
ence status on the menu. However, the system cannot always directly
determine whether the incoming video is interlaced or segmented frame. If
HD Auto Detect is selected as the video standard you must set the SF Mode
manually for some rates.
Because 1080-24/23.9 fps video is only produced in segmented frame, the
system always uses segmented frame processing whenever it operates with
a 1080-24/23.9 fps sync signal.
