Encoder Settings And Layout Presets Overview - Extron electronics SMP 351 User Manual

Encoder Settings and Layout Presets Overview

The controls within the Encoding & Layout page configure signal streaming and
encoding and also permit selection or configuration of video layouts. A user must be logged
in as an administrator to see or change these settings.
To open this page, click the Configuration tab at the top of the SMP 351 embedded
Web pages and then click the Encoding & Layout tab on the second tier of tabs.
Figure 52.
The Encoding & Layout page opens. It features two distinct panes:
• Encoding Presets – Configure audio encoding, video encoding, and streaming
parameters, then create and save or recall presets of those settings.
• Layout Presets – Set the size, position, and aspect ratio of video windows for both
channels and save those settings as a preset or recall default or user-created presets.

Each pane can be expanded by clicking the Expand (

Some of the encoder settings can also be set using the front panel menu and controls
or using Extron SIS commands (see
Layout presets are set up in this Web page or via the front panel menu.
Click the Launch Player button (above the two panes) to open a larger, stand-alone
version of the AV Controls panel Preview window in a new browser window. The player
displays the archive encoding stream.
Encoding Presets
NOTE: A user must be logged in as an administrator to see or change these settings.
Encoding presets are combinations of settings for audio and video encoding that allow
users to quickly switch between various encoder profiles for different resolution and bit
rates. The archive encoder defines the resolution of the recording and establishes the
highest quality live stream available from the unit while the confidence encoder allows for a
lower resolution live stream, such as the preview video in the AV Controls panel. Settings
changed on either encoder are applied immediately to the active streams. The SMP 351
supports up to two encodings (archive, confidence), one recording, one local output, and
multiple live streams simultaneously.
NOTE: The confidence encoder cannot exceed that of the archive encoder.
Any of the default encoding presets or user-created presets are recalled and applied
to a recording session (archive encoding) using the embedded Web pages. Presets
are also recalled for the archive stream using the front panel menu and controls (see
