If you are seeking for a practical converter that supports GPU acceleration, just read this article and you will get the converter you want as well how to enable GPU acceleration.
Normally CPU (central processing unit) is mainly responsible for the video conversion if you don’t use GPU acceleration. And the better the CPU performance is, the faster the conversion speed will become, and vice versa. However, without hardware graphics acceleration, you will face some problems. Firstly, it will unnecessarily increase your CPU utilization, which negatively impacts overall system performance. What’s more, things like system slowness and computer jam will ensue when you are converting a large file.
Therefore, you can see the importance of GPU hardware acceleration. So a GPU video converter plays a vital role in editing videos. Next, I will show you a powerful GPU accelerated video converter as well as some basic information on GPU.
GPU, short for graphics processing unit, is very efficient at manipulating computer graphics and image processing. WonderFox HD Video Converter Factory Pro is one of a pioneer in utilizing GPU acceleration to improve the efficiency of conversion.
It uses NVIDIA NVENC, NVIDIA CUDA and Intel QSV technologies to speed up outputting video formats. Here, you need to know GPU Acceleration only support H254 encoder and H265 encoder. NVIDIA NVENC and NVIDIA CUDA use the discrete graphics chips of NVIDIA to accelerate the conversion. Intel is well-known to everyone, and Intel QSV technology comes from the Corporation. Intel QSV accelerates the video conversion using the integrated graphics chip that is embedded in Intel CPU.
As for the working principle of GPU Acceleration, GPU shares the responsibility of CPU for converting the videos, which can effectually enhance the speed of conversion, even up to 25X (for the comparison of no GPU acceleration). One thing you need to know is that the performance of GPU determines the degree of improvement of the conversion speed, that is to say the better the GPU performance, the more obvious the conversion acceleration.
By the way, there are some hardware requirements on accelerating video conversion with NVIDIA NVENC technology, and can see more details from the site: https://developer.nvidia.com/video-encode-decode-gpu-support-matrix
You can see a “Hardware Acceleration” button on the right bottom of the software after entering the “Video Converter” window. And the “Hardware Acceleration” function is on by default. You can choose to close it.
Note: Some computers cannot support hardware acceleration, which may cause errors when you are converting videos. In this case, you need to turn off hardware acceleration.
After tests over and over, we find the test result listed from slow to fast: Disable acceleration < Intel i5 4430 < NVIDIA GTX 970 < Intel i7 7700 < NVIDIA GTX 1080
Tips: Discrete GPU detected, the program will utilize NVIDIA NVENC and NVIDIA CUDA. If don’t, the program adopts Intel QSV instead for Intel CPU integrated PC.
To some extent, the low speed of video conversion will bring you inconveniences and consume your time. Besides, your computer cannot work due to the CPU usage 100%. Thus, the wonderful NVENC encoder will help you convert videos at a high speed.
Converting videos with hardware acceleration is a good choice for speeding up the conversion. User guide of how to get hardware acceleration when you want to convert videos, offering faster conversion speed than ever before.
The speed of video conversion mainly depends on two aspects: one is your computer hardware specs, the other is the source video file and its output settings. The speed of video conversion will enhance with CPU and GPU acceleration technology.
