## What it is
VVenC is Fraunhofer HHI's fast and efficient open-source software encoder for the H.266/VVC video compression standard, written in C++. It offers quality/speed presets, perceptual optimization via XPSNR, task-based parallelization, and single/two-pass rate control.

## Use cases
- encode video to h.266/vvc
- compress video with better quality than hevc
- fast multithreaded vvc encoding
- software video encoder for vvc
- reduce video bitrate at same quality
- encode video from command line

## When to choose
- you need maximum compression efficiency and can use the newest codec
- you need a fast, parallelized software VVC encoder
- you want perceptually optimized encoding with rate control

## When to avoid
- you need broad playback compatibility, since VVC support is still limited
- you only need a decoder (use VVdeC instead)
- you need HEVC or AVC encoding

## Facets
- artifact type: library
- maturity: active
- function: video-processing, cli, sdk
- domain: media, developer-tools
- platform: cpp, cross-platform, cli, windows
- tags: h266, vvc, video-encoder, codec, video-compression, fraunhofer, video, linux, macos
