Functioning as a tier 3 media tech buyer, Cires21 delivers live streaming solutions to video content owners and producers through its streaming platform.

On April 16, 2026, VisualOn Inc. and Cires21 released a joint whitepaper at NAB 2026, demonstrating measurable improvements in video quality of experience (QoE) by integrating the VisualOn Optimizer, an AI-enhanced content adaptive encoding solution, into Cires21's live transcoding pipeline. The research provided independent codec-by-codec evidence that the Optimizer transforms viewer quality of experience, showing up to 19-point VMAF gains, and benchmarked H.264, HEVC, and AV1 across major hardware platforms. Previously, on March 29, 2026, Cires21 redefined video benchmarking for modern streaming infrastructure by applying a structured, reproducible methodology designed to evaluate heterogeneous video compute environments, moving beyond reliance on headline metrics such as average VMAF or bitrate alone.
