vvenc and VVdeC are the open-source VVC encoder and decoder from Fraunhofer HHI — the institute that led VVC's standardisation. vvenc handles encoding to the H.266/VVC format; VVdeC handles decoding back. Together they're the practical entry point for any team that wants to experiment with VVC without committing to expensive commercial encoders, and they're competitive with proprietary VVC implementations in both speed and quality.
The performance trajectory has been dramatic. Early vvenc (2020–2021) was painfully slow — encoding speeds of fractions of a frame per second on serious hardware. By vvenc 1.14 (January 2026), Fraunhofer reports speedups of 20× to 2,400× over the VTM reference software depending on preset, which makes VVC encoding genuinely practical for production work. At its slowest preset, vvenc produces files about 10–15 % smaller than the equivalent AV1 encode at the same VMAF — VVC's theoretical compression advantage is real, but it costs computational effort.
For a product team in 2026, vvenc is the way to evaluate VVC for your pipeline without major commercial commitments. Practical recipe: download vvenc, encode a representative sample of your catalogue, measure VMAF and bitrate, compare against your existing HEVC or AV1 ladder. If you see meaningful savings and your delivery audience has VVC hardware decode (Intel Lunar Lake PCs, MediaTek Pentonic smart TVs, growing list), the migration may be worthwhile. If not — and for most general-audience streaming in 2026, it's not — AV1 via SVT-AV1 remains the more practical choice. vvenc is the right tool for the evaluation; the rollout decision depends on your audience.

Video Encoding: A Complete Guide to Video Compression — From Pixels and Color to H.264, HEVC, AV1, Quality Metrics, and AI
vvenc and vvdec are the practical way to try H.266 today, and their presets decide whether VVC tests are realistic. Volume 1 covers vvenc in detail among encoder implementations: presets and speed, comparisons with x265 and SVT-AV1, and what VVC decoding needs on devices. Written by Nikolay Sapunov, CEO at Fora Soft.
