Encoder Setup
Video Source
The choices in the pull-down menu vary depending upon the Operating Mode you have selected.
In 1x3 MBR mode you may select from the three available input sources. Once selected, the
same input will be re-used for any additional streams.
In 2x2 LC mode the video source for Stream 1 must always be HD/SDI. The source for Stream 2
can be either HDMI or Composite.
NOTE: Composite is not recommended in 2x2 Mode.
NOTE: It is recommended in 2x2 Mode that the audio originate either from the SDI source or the Analog
source.
Video Resolution
This pull-down menu sets the video resolution for the outgoing stream. To make the stream the same
resolution as the input imply select “Follow Input”. Otherwise select an outgoing resolution from the
list.
NOTE: Up-Scaling, (creating a stream larger than the incoming resolution) is not recommended as it
usually results in severely reduced quality.
Video Bitrate
Video Bitrate (vrate) is the desired encoded rate of the outgoing video. Settings are expected in Kilobits
per second. For example, you may use 100000; 100k; 100K etc. You may also use 1m; 2m, etc
representing Megabits per second. 1G, etc is not accepted.
NOTE: If a setting is out of bounds for the encoder you will receive the message “status: !Error: Bad
vrate xK”. This only indicates that the setting is not acceptable to Talon. It is possible to set a value that
is acceptable to Talon, but is not adequate to support quality video.
Frame Rate Divider
The frame rate for the output video is expressed as the input video size divided by the “Frame Rate
Divider”. A value of 1 means the output will be the same frame rate as the input. A value of 2 means ½
of the input rate and so on.
Video Profile
Talon supports three h.264 encoding profiles; Baseline, Main and High. Profile selection should
be based on the target audience of the encoded video.
Baseline is the lowest level profile and is suitable for streaming to a broad spectrum of internet
connected devices including most older smart phones.
Main is the default setting. It is suitable for most web streaming including HD. It is also good for
most modern smart phones.
High is primarily used for broadcast, or for saving high-quality HD to file. It supports up to
1080p/60 video.
