TECHNICAL
NVIDIA NVENC NVIDIA’s NVENC is a staple for high-density transcoding. The data indicates that VisualOn’s Optimizer unlocks the full potential of NVIDIA hardware, delivering massive gains across all tested codecs.
H.264/AVC (NETINT)
Similar to HEVC, the optimisation strategy clearly prioritises lifting the “floor” of the video quality to ensure no user suffers poor experience.

The results here are striking. The Optimizer bridges the gap between hardware speed and software quality, boosting 108Op scores by nearly 8 points.

Note: While J0B0p experienced a regression, the mid-range resolutions saw consistent improvement.

Intel OneVPL / OuickSync Intel’s OuickSync is ubiquitous in media processing. Standard OuickSync encoding often sees a sharp “cliff” in quality as resolution drops. The VisualOn Optimizer successfully mitigates this drop-off.

Even with the modern AVl codec, the Optimizer provides essential gains, particularly stabilising the lower resolutions.
The win is clear here, with 720p reaching near-transparent quality (-96 VMAF), 576p transitioning from poor to high quality (-92 VMAF), and low-resolution improving from unacceptably degraded to serviceable.

NETINT NETINT offers high-performance ASIC-based transcoding. The testing revealed a specific behaviour pattern: while top- tier(1080p) scores remained stable, the Optimizer revolutionised the quality of the lower bitrate ladders, which are critical for mobile users on unstable networks.
