MPEG4 Encoder Video
Video Format The format can be configured to be NTSC (30fps) ,PAL (25fps) or
PALM (30fps). PAL-M is a video format standard used in Brazil. The
main difference between PAL and PAL-M is a lower resolution (525
lines instead of 625) and a higher frame count (30 frames per second
at 60Hz versus 25 frames per second at 50Hz).
Video Aspect Ratio Aspect ratio is the ratio of the width of the image to the height of the
image. Standard TV images generally use an aspect ratio of 4:3; DVD
players and some camera can produce 16:9. Set this value to match the
video input source, either 4:3 or 16:9.
Video Input Type The input can be changed to accept either S-video or composite
(BNC). Note that model 9174-4200 (VBSSM) does not support
S-Video.
