Using 4K Blu-ray to H.265 Encoders on NVIDIA GPU Hardware Acceleration

Step 1. Launch the best Blu-ray to H.265/HEVC Ripper and load Blu-ray discs with BD Drive.

Step 2. Click “Format” to find “Common Video” catalogue, select “H.265 Video(*.mp4)”. What’s more, you can also rip Blu-ray to H.264 MP4,WMV or MKV for watching.

Step 3. Optional – If you think the video size this not suitable for playback, you can first choose any one of the provided type, then change the settings, see the following picture:

Please remember the file size is based more on bitrate than resolution which means bitrate higher results in big file size, and lower visible quality loss.

Step 4. Click “Convert” to start ripping 4K Blu-ray to H.265/HEVC MP4, when completed, click “Open” to find the generated files. Obviously, it is easy to use software to convert 4K Blu-ray to H.265 for for enjoying.

Additional Tips 1: The Advantages of HEVC/H.265

1. Compared to the high computational and profile complexity of the H.264/AVC, HEVC/H.265 ensures 50% bit rate reduction at the same image quality

2. In terms of the real-time encoding, HEVC/H.265 remains the same image quality but with 35% bandwidth consumption reduction

3. HEVC/H.265 supports higher video resolution, including 2K and 4K

4. HEVC is good for cost saving. It allows transferring SD and HD content on low bit rate connection

Additional Tips 2: Using H264 and H265 Encoders on NVIDIA GPUs

The LEAD H264 Encoder (4.0) and LEAD H265 Encoder (3.0) are capable of accelerating compression on NVIDIA GPUs with CUDA. There are two technologies for accelerating H264 compression on NVIDIA devices:

• NVCUVENC is available on most NVIDIA GPUs, but has been deprecated since August 2014. The newest NVIDIA device drivers do not support this technology, but you can get it by installing an older version of the display driver. For more information, refer to https://developer.nvidia.com/nvidia-video-codec-sdk. The LEAD H264 Encoder can use the NVCUVENC technology if it is available.
• NVENC technology is available on newer GPUs. The page mentioned above contains a list of graphics cards supported by the NVENC technology. The LEAD H264 Encoder can use the NVENC technology if it is available.

The NVENC compression is available if the GPU Capability displayed in the NVIDIA CUDA Info mesage box is at least 3.0. If the GPU capability is less than 3.0, then you need to use the NVCUVENC capability by installing an older version of the display driver. See the following examples of message boxes which illustrate graphics cards with and without NVENC capability.

If you have a NVIDIA graphics card but the LEAD H264 Encoder does not enable the CUDA hardware acceleration, you should first check whether your card supports the NVENC technology. If it does, you might have to install the newest graphics driver. You can also check the NVENC support by opening the H264 encoder property page and clicking the CUDA Info button. If the card supports the NVENC technology, the message box should look like the following figure (notice that the message box says NVCUVENC is not available, but NVENC is available):

If the message box does not indicate that NVENC compression is available, you will need to install a version of the NVIDIA disply driver that includes the NVCUVENC.dll. The NVIDIA page mentioned at the top of this page provides details on which driver version to install and when you can get it from.

If NVENC compression is not available, the CUDA info property page will look like the following figure:

The following unofficial sequence also seems to work to get NVCUVENC support with the new NVIDIA drivers:

1. Install the old driver.
2. Make a copy of NVCUVENC.dll (or rename it).
3. Install the new driver.
4. Copy the saved NVCUVENC.dll to the system folder or rename it back.

Now, you may have no issues about rip 4k Blu-ray movies to H.265 mp4 video immediately.
