Encoding Presets
Encoding presets are combinations of settings for audio and video encoding. The recording
uses the highest quality signal encoding (archive encoding), and the preview (confidence
view) displayed within the embedded web pages uses the lowest quality encoding
(confidence encoding) of the encoding streams.

Any of the default encoder presets or user-created presets can be recalled and applied to
a recording session (archive encoder) and stream using the embedded web pages. Presets
can also be recalled using the front panel menu and controls (see

The first 18 presets are factory set. Presets 1 through 9 are for popular, general AV uses
with settings from 1080p High (1080p resolution at 8000 Kbps) to Confidence (515x288
at 350 Kbps). Presets 10 through 18 provide convenient settings that make it easy to
integrate the SMP into an Opencast system, especially when using dual channel encoding.
Some are tailored for speaker flavor, some for presentation flavor. Factory defined
presets 33 through 42 support Panopto quality settings. For more information, see the

An overview of encoding
Each of the two encoders for the SMP 300 Series can be used for multiple purposes. The
table below shows how each encoder is typically used and the differences. For details, see
the SMP 300 Series Embedded Web Pages Help File.

one local output, and live streams simultaneously.
