Its streaming platform, based on hardware, software, and cloud models, provides encoding, recording, and monitoring solutions for live streaming from any source to any user device.
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.
