Using Encoding Presets
The Encoding Presets panel is used to recall and save presets. Saving a preset saves the
current set of encoding parameters for the current output stream. Recalling a preset recalls
and applies a saved preset to the current output stream. Encoding presets allow the user to
quickly switch between various encoder profiles based on the target resolution or bitrate.
Sixteen available encoding presets are used to recall or save settings. The table below details
the settings that are saved and recalled in an encoding preset.
