Encode HEVC: Utilizing Nvidia GPU Hardware Acceleration

Spread the love

HEVC (High Efficiency Video Coding), a video compression standard, is developed to have a higher coding efficiency and improved video quality. With double data compression ratio, HEVC only requires half bitrate to keep the same video quality compared to H.264/MPEG-4 AVC. In other words, HEVC brings better video quality at the same bitrate. HEVC codec is the software to compress or decompress HEVC video. It can be an encoder for compression only or decoder for decompression only. With HEVC codec, people can create and play back 4K/8K videos on computers or devices without incompatibility problem.


Concerning H.265 or HEVC

Why should you care about converting to H.265 for your video files? Several very important reasons — and the most important is that you soon won’t have much choice. The H.265 format, often called HEVC (high efficiency video coding), is being adopted as the new standard, particularly at the commercial level, and video creators/editors are slowly but surely being required to use it — especially for a little thing called 4K video.

In this guide, we will offers you best 2 methods of encode HEVC to utilizing Nvidia GPU Hardware Acceleration and top 5 HEVC Encoders for users. Just choose the way as you like.

Part I: How to Encode HEVC: Utilizing Nvidia GPU Hardware Acceleration

If you happen to have a Maxwell-based Nvidia graphics card from the GeForce 900 series or later, you can utilize your GPU’s dedicated HEVC encoding block to transcode videos into HEVC significantly faster than by using Handbrake. While only some 900 series GPUs feature a HEVC decoding block, all include HEVC encoders, which is going to come in handy.

While performance is significantly improved by using Nvidia’s HEVC encoder, NVENC, it comes at a cost of quality. Simply put, you’re not going to get as good a quality at the same bitrates using Nvidia’s encoder compared to using Handbrake. You can check out a comparison on the pages that follow, but essentially the quality of Nvidia HEVC encodes is equivalent to a good H.264 encode, albeit with a much faster encode time.

Anyway, if you want to use NVENC to encode HEVC videos, you’ll need to download a program called StaxRip. The version I used for this guide was x64 beta.

Refer to the step guide >> Best Setting x265 With StaxRip – Keep Quality With Small File Size.

Part II: Best HEVC Encoder With Utilizing Nvidia GPU Hardware Acceleration

Here, Pavtube Video Converter Ultimate (review) is put on the top of the H.265 encoder list, which can handle both H.265 4K video encoding and decoding successful. The most wonderful feature this HEVC video encoder gives is its H.265 encoding speed – up to 5× faster than other common H.265 video converters empower, thanks to its hardware acceleration support, Hyper Threading tech and Multiple CPU cores support. The output encoded H.265 video quality is quite impressive, the same as that of original video. Users are allowed to decode, encode, transcode H.265 video up to 1080P, 4K UHD, and even 8K FUHD. It’s a no brainer to start the H.265 decoder & encoder. A brief guide on how to encode video to H.265 is covered below.

For Mac users, you can turn to Pavtube iMedia Converter for Mac for further usage (Mac OS Sierra included).

NVIDIA CUDA & AMD APP Supported Pavtube Products

Pavtube products support newest NVIDIA CUDA & AMD APP technology in video decoding to improve performance and ensure users much faster conversion speed than ever before when coping/ripping/converting DVD/Blu-ray/video, since more CPU resources are spared because of NVIDIA CUDA’s harnessing the power of GPU and AMD APP’s co-using of GPU and CPU.

NVIDIA CUDA: DVD Ripper, Blu-ray Copy, Blu-ray Ripper and Video Converter.
AMD APP: Blu-ray Copy, Blu-ray Ripper, Video Converter, and more products in the future.

HEVC CUDA Hardware Acceleration

HEVC CUDA Hardware Acceleration is the latest achievement of Pavtube to help its customers improve the user experience of their purchased products, to be more specific, DVD Ripper, Blu-ray Ripper and Video Converter. Technically speaking, Pavtube HEVC CUDA takes advantage of NVIDIA’s latest high end graphics card iterations which are capable of h.265 encoding, aka HEVC encoding, and also the CUDA hardware acceleration technology. Our test results show that it can speed the conversion up exponentially, approximately 30 times faster than software encoding.

Hardware and System Requirements

Before you can benefit from the HEVC CUDA, you need to make sure your computer is geared up with one of the three NVIDIA’s HEVC encoding capable graphics card, which are the GeForce GTX 960, GeForce GTX 970, Nvidia GTX 1060 and GeForce GTX 980. This is the only must-have thing it requires, no other special demands.

Enable HEVC CUDA in Pavtube H.265 Encoder

Pavtube HEVC CUDA is applied in three products, namely, DVD Ripper, Blu-ray Ripper and Video Converter. So customers who own one of these products are lucky enough to take the first bite as soon as the official version is available to the public. But remember, to use this feature, users to must enable this option at the Common Settings> General>A/V Codec, and then set both the video decoder and video encoder as CUDA there.
