CUDA HEVC Encoder | 2019 Best CUDA H.265 Video Converter for Windows 10

Get idea on how to enable CUDA HEVC encoder and decoder to accelerate UHD 4K/8K and HD video conversions on Windows (10) PC.

By on

As the successor of H.264/AVC video compression standard, HEVC (also named H.265) brings about twice as efficient as H.264, which contributes to its rising support on desktop and mobile systems (e.g. Windows 10 & iOS 11/12), online streaming sites (e.g. Netflix & YouTube), video shooting devices like GoPro action camera and media player like VLC. Handling HEVC video on Windows computer has much requirement on hardware performance. But if your PC has equipped with HEVC-supported GPU like CUDA, things will become much easier.

CUDA, full name Compute Unified Device Architecture, is a parallel computing platform developed by Nvidia to do more effective processing and deliver more convenient programming environment for both software developer and engineer. In early years, graphics/video cards are only in charge of displaying 2D, 3D images to screen, relieving the heaving task of CPU. But nowadays, CUDA-enabled graphics processing unit (commonly known as GPU) is not only able to accelerate graphics rendering, video interconversion, but also used even for physical simulations, molecular dynamics, mining cryptocurrencies and so on.

Fast Convert (4K/8K) Video with CUDA HEVC Activated

WinX HD Video Converter Deluxe is the first HD video transferring tool that supports both CUDA HEVC/X265 encoder and decoder, to make video conversion from H.265 or to H.265 as computer's performance allows.

  • OS: Windows 10 (32 & 64 bit) or lower

Nvidia CUDA has 6 generations in total since being released in 2007. And they are Tesla, Fermi, Kepler, Maxwell, Pascal, and Volta respectively, among which we general computer users can only have chance to make use of on HEVC/H.265 entertainment is GM20x GPUs powered by Maxwell second generation architecture. Others like Quadro and Telsla are often used by professional users or researchers.

    Detailed Log on Nvidia (CUDA) HEVC Encoder & Decoder
  • - In September 2014, the world's first HEVC encoder NVENC came out with the releasing of GeForce GTX 980 (GM204) and GTX 970 (GM204).
    - In 2015, Nvidia launched GeForce GTX 960 and 950 (GM206) respectively with fully support for HEVC( Main/Main10) hardware decoder.
    - In 2016, Nvidia released GeForce GTX 1080/1070 (GP104), GeForce GTX 1060 (GP106), GeForce GTX 1050Ti and 1050 (GP107)with full fixed function HEVC Main10/Main12 hardware decoder.
    - In 2017, another three were out including full fixed function HEVC Main10/Main12 hardware decoder, and they are GeForce GTX 1080 Ti (GP102), GeForce GT 1030 (GP108), and GeForce GTX 1070 Ti (GP104). ...

How to Fast Convert Video from/to HEVC on Windows (10) PC?
[CUDA HEVC/H.265 Encoder and Decoder Enabled]

We have to do video conversion regarding HEVC codec in many situations, such as:

Q1: Most of my acquired video files are x.264 or .mkv. However, some are encoded HEVC x.265.... Which my media player won't accept. What's the easiest way to convert HEVC to MP4 or equivalent, so I can put the video file on a USB stick and play it on my TV ? (FROM VideoHelp)

Q2: I'm trying to find the best video converter for transcoding video to x265. I've tried Handbrake. It's nice but I could not figure out how to enable GPU Acceleration. System Specs: GeForce GTX 970, i5-3570k @4.3Ghz, 16GB RAM, Windows 10 Pro x64 (FROM tom's guide)

Hardware trancoding is unquestionably faster than software transcoding. Compared to open-sourced HandBrake with Intel Quick Sync Video support to accelerate HEVC to H.264 video conversion speed, WinX HD Video Converter Deluxe gives more options. If our computer has embedded with Nvidia CUDA/NVENC graphics card with HEVC codec, be it any of the Maxwell-based GeForce products (GM20X), WinX HD Video Converter calls CUDA to decode and encode video from or to H.265 in boosted speed. Now let's turn to how to use WinX HD Video Converter directly.

Step 1. Free download and install it following the wizard.
CUDA HEVC Accelerated H.265 Conversion

Step 2. Open it and click either of the "+ Video" icon to browse, select and click Open to load video. This video converter supports batch convert videos, so you can select multiple video sources to load.

Step 3. Choose output video format at the well-organized "Output Profile" list.
If you're converting HEVC video to H.264 MP4, just choose "MP4 Video" at General Profiles.
If you're changing video to HEVC in .mkv format, just choose "HEVC Video" at PC General Video.

Step 4. Once the output video is confirmed, you would go back to the main UI of software, where two hardware encoder options - Intel and nVIDIA are listed right below the video preview window. WinX program can auto-detect and check what your PC supports.

If you want to change video bit rate in VBR or CBR mode, adjust video resolution/aspect ratio etc., do it in setting dialog box by clicking sawtooth icon. If you'd like to add some external subtitle, or do video cropping/trimming, just open Edit option to do so.

Step 5. Press "RUN" to start accelerated video conversion.

Why WinX HD Video Converter Deluxe is your right choice?

More and more video converter software starts to add support for CPU (Intel QSV) and GPU (Nvidia CUDA/NEVNC) hardware acceleration. But most of them only take advantage of hardware to do video encoding. Only WinX passes the whole video transferring process from decoding to encoding to hardware, shortening conversion time greatly. Although we cannot figure out a specific number for time saving (because it varies from video types/sizes and PC specs), we deliver the most real hardware accelerated video conversion solution.
