Encoder Tab
SD-only Stream Settings: Provides a SD stream of the video input source.
Video Settings:
Video Encoder Format: MPEG-2 or MPEG-4/H.264
SD Video Bitrate (Mbps): 2 to 8 incremented by 0.1 in MPEG-2, and 1 to 4 in H.264
Video Mode Flag: Field-Motion, Frame-only, Field-only, adjusts video encoder modes for decoder compatibility
Field-Motion: Field encoding mode with algorithm enhancements to improve video quality. Use Field-
Motion encoding mode to improve video quality when video input is interlaced, for example 480i or 1080i.
Some decoders may have compatibility issues when decoding field encoding. Video quality test equipment
readings may be inaccurate when using this mode.
Frame-Only: Frame encoding mode. Use Frame-Only mode when video input is progressive for example
720P. Frame-Only mode can be used to encode interlaced video, for example 480i or 1080i.
Field-Only: Field encoding mode. Use Field-Only mode when video input is interlaced for example 480i or
1080i. Some decoders may have compatibility issues when decoding field encoding.
NOTE: If the video input is 720P the encoding mode will automatically default to Frame-only mode, even if Field-
Motion or Field-Only modes are selected in the menu.
Audio Settings
:
Audio Encoder Format: Select MP2 for MPEG-1 Audio Layer 2; AC-3 for Dolby Digital AC-3; AAC (Advanced Audio Coding)
Audio DialNorm: Adjustable from -1 to -31 dB. Provides meta-data for audio playback gain for Dolby AC-3 compression.
Audio Bitrate: 128, 192, 320 or 384 Kbps
NOTE: 320kbps is an option for audio bitrate in MP2 and AAC only
Transport Stream Settings:
SD TS Bitrate (Mbps): 2 to 25 incremented by .125
Stuffing Output:
Enable or Disable, Enable will include transport stream null packet stuffing to produce a fixed-
bitrate TS
IP Settings:
Destination IP / Destination Port: User defined unicast or muliticast IP address and port number determined by
downstream network connectivity device.
IP Stream TTL: 1 to 255, determined by application
