Encoding and Output

Signals from the two input channels, a background image, and metadata are combined
in a user-configurable layout and encoded into streams. The SMP 351 can encode a high
quality stream (for recording and optional live streaming) and also encode a lower resolution
stream (for preview within its embedded Web pages and optional live streaming). See the
Encoder Settings and Layout Presets Overview
the two encoding types (archive and confidence). The video output can be scaled and its
aspect ratio modified. The SMP 351 also outputs high quality encoded HDMI video with
embedded audio on a single output for display on any HDMI display, supporting resolutions
up to 1920x1080 at 60 Hz.
