Presets and Tuning Options

Presets

Aurora1-RTC has ten predefined presets that optimize the trade-off between encoding speed (encoded frames per second) and compression efficiency (quality per bit in the bitstream).

When you use faster presets, the encoder takes shortcuts to improve performance at the expense of quality and compression efficiency. When you use slower presets, Aurora1-RTC tests more encoding options, using more computations to achieve the best quality at your selected bit rate.

The presets adjust encoder parameters as shown in the following table. Any parameters below that are specified in your commandline will be changed from the value specified by the preset.

  • medium-2
  • medium-1
  • medium
  • fast
  • faster
  • veryfast
  • ultrafast-2
