Clear alpine lake with calm green-blue water revealing rocks beneath the surface near the shore. Reeds and a walking path line the left side, while forested hills and snow-capped mountains rise in the distance under a bright blue sky with scattered clouds.

Sunset over a calm lake with mountains in silhouette along the horizon. The sky glows orange and gold fading into deep blue, reflected smoothly on the water’s surface. A small pier extends from the right, and a lone duck creates gentle ripples in the foreground under a clear evening sky.

I wonder how many know that VVC is ISO/IEC 23090-3 and what’s ISO/IEC 23090 in general 🫀

05.02.2026 16:52 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Yes, it’s an ITU and ISO standard. The common name for the successor will be not known until it’s ratified. In ITU, the next free number is H.267. In ISO, it will be 5-digit number, either new one or part of an existing one.

Draft Joint Call for Proposals on video compression with capability beyond VVC is available. This cryptic title defines the CfP for whatever comes after VVC, most likely will be H.267 in ITU-T terms. jvet-experts.org/doc_end_user...
