Currently, many graphics cards have powerful computing power. In the case of video transcoding, which requires large computing power, it is especially important to use a graphics card to help computing. Mainstream graphics card developers offer GPU (Graphics Processing Unit) code to support transcoding, like NVIDIA-CUDA, AMD-amf, INTER-QSV. So how do you enable these features?
1. Make sure your graphics card is valid
Graphics cards that support video acceleration are needed：
2. Turn on GPU acceleration in the transcoding software
a). Turn on GPU acceleration in OpenCloner Ripper.
OpenCloner Ripper is a DVD/Bluray rip software and a transcoding software. It can convert high quality video. Open the OpenCloner Ripper setup window and check “Enable GPU accelerated when encoding H264/H265”. (This option is off by default. If the system supports acceleration, there will be a mouse prompt “Your system supports GPU acceleration” display.
b). Turn on GPU acceleration in DVD-cloner
Open the DVD-Cloner setup window, enter the MKV tab, and select “Enabled encoding H264/H265 with HST”. DVD-Cloner is a DVD copy software, and it can also convert DVD to MKV format.
