2023 Fastest CUDA/GPU Video Converter Review

What Is CUDA/GPU Acceleration?

If asked which is the best and fastest way to convert and compress a large number of video files each over 1GB, I would say just to convert video to MP4 using both CPU and GPU acceleration, taking the advantage of Intel QSV, Nvidia CUDA/NVENC or AMD. Hardware acceleration is very important for 4K video conversion and compression. This time we will primarily talk about GPU accelerated video encoding technology, followed by presenting a fastest CUDA video converter for Windows and Mac.

Firstly, what is CUDA or what is GPU acceleration? CUDA, a parallel computing platform made by Nvidia, uses GPU hardware to perform accelerated interconversion of video file formats, which consequently releases your CPU. In fact, both QSV and CUDA/NVENC belong to GPU acceleration.

"I'm searching for FREE CUDA optimized video converter. I'm currently using Format Factory, it's kinda slow. I read that CUDA video converting is 5X faster."

Format Factory is a freeware well-known for being multifunctional, converting DVD video using multi-thread, however no GPU acceleration is available. Another free video transcoder - HandBrake - also doesn't support CUDA acceleration. It is true that how fast you can convert a 4K (4K H.264/HEVC/AVC) video depends on not only the computing power of your device, but also the video converter software. That's why WinX HD Video Converter Deluxe stands out, being a fastest CUDA/GPU video converter, enabling users to make full use of their computer's GPU hardware.

In addition to CUDA, WinX HD Video Converter Deluxe also supports NVIDIA NVENC and Intel QSV hardware acceleration. Uniquely applying Level-3 hardware acceleration, this GPU-accelerated video converter keeps a good balance among the speed of video processing, output quality and file size.

How to Convert Video Using CUDA/AMD GPU Accelerated Video Converter?

Firstly, you should have a qualified computer, which allows you to exert CUDA/NVENC or QSV. Have no idea how to check if your computer supports CUDA or not? Just open this NVIDIA page to check if your NVIDIA GPU is CUDA-enabled, or open WinX HD Video Converter Deluxe, and see if nVIDIA is selectable (if it is, it means that it is CUDA/NVENC- supported). Then follow the next instruction of how to convert video with a fastest CUDA converter.

Step 1. Download the fastest CUDA video converter for Windows/Mac.

Free get WinX HD Video Converter Deluxe for Windows or Mac based on your need, and then double click the downloaded .exe/.dmg file to follow the setup wizard and finish the clean installment. The next steps are an example of how to convert MKV to iPhone X using NVIDIA CUDA GPU acceleration.

Step 2. Run the CUDA video converter.

Open the program and click "+ Video" button to add a video. For example, choose a local 4K movie file in MKV and click Open to get it fully loaded. Or you can just drag and drop a file in the main interface to load the content.

Step 3. Select iPhone X as Output Profile.

There pops up the Output Profile window. Go to the Devices Profiles, click "Apple Device" > "to iPhone Video", followed by selecting "iPhone X (H264)" or iPhone 8, Plus (H264) and click OK.

Step 4. Start converting MKV to iPhone X.

To turn on the CUDA hardware encoder, please check the "nVIDIA" box. And then hit button "RUN" to start converting MKV to iPhone 11 (H.264) at a lightning speed using the fastest CUDA/GPU accelerated video converter.
