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.
