VBrick 9000 Encoder Admin Guide
Description
Sets the video encoding resolution (the width and height
respectively) of the compressed video stream. The VBrick encoder
has high quality video up/downscaling built-in to let you choose
from a wide range of standard encode resolutions regardless of the
Video Format of your source video. For example, you can use a
1080p60 High Definition video input source and have the encoder
downscale the video to a Standard Definition resolution so it can be
streamed with good quality at bit rates to match your network or to
match the processing power and display resolution of your decoders,
STBs or PC players. When the aspect ratio of the encode resolution
does not match the aspect ratio of the input, the encoder will
letterbox. Available video resolutions include:
1920x1080, 1680x1050, 1680x1008, 1600x1200, 1400x1050,
1366x768, 1360x768, 1344x1074, 1280x1024, 1280x768, 1280x720,
1120x700, 1024x768, 960x544, 832x666, 832x520, 832x500, 800x600,
720x576, 720x480, 656x410, 656x394, 656x368, 640x480, 512x288,
400x304, 384x288, 352x288, 352x240, 320x240, 256x144, 192x144,
176x128, 176x144, 128x96.
32,000–20,000,000 bits/sec. Constant bit rate. Default = 750,000.
This number can only be changed in 1000 bits/sec increments. It
represents how much data the encoder will send out each second to
carry video to a player. The word target is used because the encoder
can vary its bit rate slightly in response to the amount of detail in the
movie or camera output. The more data the encoder sends in one
second, the more clearly the details of the video will be seen on a
player. It is not always desirable to send the most possible data, since
that requires a large network "pipe" (connection). The trade-off is
the level of detail in the video with the use of smaller network
connections. The encoder tries to encode the video at a quality that
will (on average) match the Target Bit Rate. The larger the number, the
better the quality but this can potentially limit the number of clients that can
connect to the encoder.
