HST™ (H.264 Speedup Tech) is an innovative advanced technology developed by OpenCloner Inc. Open Blu-ray ripper adopts this technology to largely increase the conversion speed of a Blu-ray movie. This speedup is realized through optimizing the GPU of the video card. And users must have an NVIDIA video card.

Comparison chart

Compare each Blu-ray movie's different conversion time with different Blu-ray rippers.

List of NVIDIA video cards
(Many applications require at least 256MB of dedicated VRAM. We recommend high-end video cards, which will make the conversion faster and more stable.)
