Orange
: No 3:2 pulldown sensed in 60i/59.94i input signal.
Input video is being converted to 24p/23.976p using a conver-
sion process which drops frames and may introduce judder.
White
: 3:2 pulldown sensed in 60i/59.94i input video signal.
Input video signal is being converted to 24p/23.976p using 3:2
pulldown removal which recreates 24p/23.976p as it is cap-
tured from the camera’s shutter.
It is important that 3:2 pulldown be sensed before beginning a recording. If recording begins before 3:2
pulldown is sensed, 3:2 pulldown will not be applied properly.
Up and Down Conversion
Standard-definition video resolution employs a 4:3 aspect ratio, and high-definition video resolution
employs a 16:9 aspect ratio. Up-conversion is the process of fitting standard-definition video (with a
4:3 aspect ratio) into a high-definition, 16:9 frame. Down-conversion is the opposite process.
The PIX 260i has various options for up and down conversion:
Down-Conversion
Letterbox
: Maintains the same height and width ratio. Results in blank bar at top and bottom of im-
age.
Crop
: Left and right side of image is cropped to fit into 4:3. Results in missing image at sides of pic-
ture.
Anamorphic
: Image is horizontally squashed to fit into 4:3. Results in a narrow looking image.
