Real Video, Real Results: 40%~80% Faster & Visibly Better with V4.0

Winxvideo AI 4.0 addresses one of the biggest challenges in AI video enhancement: time. By optimizing GPU memory allocation and refining neural network efficiency, it significantly accelerates rendering without taxing your system. Rigorous tests on NVIDIA GPUs prove that Winxvideo AI 4.0 dramatically accelerates video enhancement without sacrificing quality. Below are real-world benchmarks comparing v4.0 vs. v3.9:

Test 1. Upscale from 2K to 4K

Quality result:

As illustrated in the accompanying image, Winxvideo AI 4.0 delivers overall sharpeness improvements when upscaling and denoising from 2K to 4K. It also reduces blurriness and pixelation noticeably, resulting in a sharper and more defined picture. Fine lines and edges are rendered with exceptional clarity, revealing details that are less distinct in the V3.9 output.

How Does It Compare with Other Video Enhancers?

When it comes to speed, Winxvideo AI 4.0 leaves the competition behind. In direct head-to-head tests with other leading desktop video enhancers, including Topaz, Winxvideo AI 4.0 boasts 24% to 50% faster processing speeds! And the best part? It achieves this with remarkably lower CPU usage, often staying under 50% even during demanding tasks.

For example(on an AMD Radeon RX 6700 XT):

• Winxvideo AI 4.0: upscale a 1080p video to 4K = 41s, 4% GPU usage and 46% CPU
• Topaz: upscale a 1080p video to 4K = 1 min 19s, 55 GPU usage and 90% CPU usage (that means: Winxvideo AI is 48.01% faster in time and 90% increase in FPS speed). Check Winxvideo AI vs Topaz Video AI speed test >>
