HST (H.264 Speedup Tech) is a hard-coded H.264 technology. It uses CPU decoding and GPU encoding, which greatly improved the H.264 compression speed. It works together with the GPU, and a discrete graphics card is needed.
NVIDIA CUDA
AMD Video Transcoding
Intel Quick Sync Video
Please enable the option “Enable encoding H.264 with HST” in “Setup” - “Blu-ray”. You can also click “Check” to see whether your system supports HST.
You need to install a graphics card as well as its corresponding driver. For NVIDIA graphics cards, please select a driver that supports CUDA, and drivers provided by Microsoft do not support HST. In addition, early graphics cards do not support GPU acceleration, so please make sure that the card is produced after 2015.
It is because the data units compressed by AMD GPU lack necessary information. This is caused by a defect in AMD. In this case, you are recommended to close the HST function.
In the process of ripping a Blu-ray movie, if you select to keep HD audio, the output size will generally become much larger. HD audio tracks occupy a lot of space, so you are recommended to convert HD audio into normal formats to save space.
It takes about 1 hour to rip a Blu-ray movie with H.264 or H.265 encoding, while it takes about 40 minutes to rip a Blu-ray movie without re-encoding.
Yes. Please select your desired option in “Setup” – “MKV”.
Currently, DVD-Cloner can remove Blu-ray copy protections including AACS, BD+, UOPs and Cinavia.
The core data of removing Blu-ray protections are stored in the server. Internet is needed to download necessary data in the process of copying. 1KB data will be downloaded for cracking AACS, about 1.5MB for BD+ and 1GB for Cinavia.
Some Blu-ray movies, due to the upgrade of AACS MKB version, cannot be decrypted temporarily. We need to upgrade the background database for cracking them, please wait for a few days and then try again.
