iQIYI’s QAV1 Encoder Achieves High Compression and Bandwidth Savings Using AV1 and Deep Learning

iQIYI’s QAV1 encoder, which combines the next‑generation AV1 codec with deep‑learning techniques, delivers 20‑42% bandwidth savings and up to 36% higher compression efficiency than x265 while maintaining ultrafast 60 fps encoding speeds, enabling high‑quality 4K/8K streaming and live broadcast across devices.

Interview on iQIYI's QAV1 AV1 Encoder and Its Technical Advantages

iQIYI’s scientist Wang Zhihang explains that their home‑grown QAV1 AV1 encoder, built to overcome AV1’s high computational cost, delivers roughly five‑times faster encoding than SVT‑AV1 while matching compression efficiency, uses less than half the resources of x265, supports 1080p‑8K, multiple speed tiers, and is poised for broader hardware adoption as mobile SoCs add native AV1 decoding.

iQIYI Deploys AV1 Video Codec and Introduces QAV1 Encoder for Bandwidth Savings

iQIYI has become the first Chinese video platform to deploy the open‑source AV1 codec on its PC web and Android apps, cutting video file size by about 20%, and its in‑house QAV1 encoder further reduces bitrate over 40% and runs roughly five times faster than competing encoders, enabling smoother 4K/8K streaming while saving bandwidth.
