Usage

Overview

The encoder project includes two encoder executables, a simple encoder app (vvencapp) and a full featured expert encoder (vvencFFapp).

How to use the simple encoder app

The simple encoder app (vvencapp) can be used in one of five predefined presets. Each preset represents a different tradeoff between encoder runtime and video quality. In the slowest preset, the encoder reaches the highest compression gain, whilst in the fastest preset the runtime is significantly decreased. These preset configurations have been determined based on the Pareto optimal configuration set of the encoder configuration space, which is detailed in [9]. A list of the main encoder command line parameters is shown in the table.

Option	Default	Description
--help,-h		Show basic help
--input	not set	Raw yuv input file (use - to read from standard input)
--size	1920x1080	Input file resolution (width x height)
--framescale	1	The denominator of the framerate to enable fractional rate specification.
--fps	60/1	Fractional framerate specification, setting --framerate and --framescale using a single parameter with a fraction syntax (denominator defaults to 1 if not present).
--format
