Nvenc h264: Nvidia NVENC Encoder for Screen/Video recording (H264, HEVC)

Nvidia NVENC Encoder for Screen/Video recording (h364, HEVC)

  • If you use a high-end NVIDIA graphics card and install the latest NVIDIA graphics card driver, you will be able to enhance the recording ability of Bandicam by using the GPU of the graphics card.
  • If you use GTX 600 series or higher graphics cards, you will be able to use the Nvidia NVENC h364 encoder which allows you to record the target with high speed, high compression ratio, and excellent quality.
  • If you use GTX 950 series or higher graphics cards (Maxwell, GM20x), you will be able to use the Nvidia NVENC HEVC(H.265) encoder which is better at compression than the NVENC H.264 encoder.

HEVC vs H.264 — Which one is better?

HEVC (H.265) is better at compression than H.264. The video quality of HEVC will be better than H.264 if the file size is the same.
The file size of HEVC is smaller than that of H. 264 if the video quality is the same.

However, some media players don’t support HEVC and HEVC uses more CPU usage than H.264.

Users have to choose the proper codec to meet their needs.

HEVC vs H.264 — Size, Quality, and Speed

The table below shows the file size, video quality, and codec speed.




Codec Size Quality Speed Description
HEVC 33.5 MB Better Fast Better than H.264 at compression

Contents ManualPart 1 NVIDIA CUDA DetailsPart 2 What is NVIDIA NVENC and How Does It Work?Part 3 Best High-Speed ​​Video Converter for Your MediaPart 4 Conclusion

Part 1 NVIDIA CUDA Details

Compute Unified Device Architecture, known as CUDA, is a parallel computing platform and interface model for application programming developed by NVIDIA . NVIDIA uses this platform for its own graphics processing unit (GPU) computing purposes to speed up their computing processes. nine0005

CUDA allows developers to increase the speed of computationally intensive applications by using GPU power for parts of the computation that can be parallelized. With CUDA, software developers and researchers can send Fortran, C, and C++ codes directly to GPUs without using assembly code. This rationalization process takes advantage of what is called parallel computing where thousands of threads or tasks are running at the same time. nine0005

Although other GPU APIs have been proposed such as OpenCL and there are other GPU manufacturers such as AMD, the NVIDIA CUDA-NVIDIA GPU combination still dominates most application areas. This includes deep learning. What’s more, this combination is at the heart of some of the world’s fastest computers.

NVIDIA GPUs (GeForce)

GeForce is NVIDIA’s brand for its GPUs and represents their product lines at the consumer level. The latest design, which was the GeForce 20 Superseries, is the 17th generation of NVIDIA GeForce designs. The first generations of products were discrete GPUs designed for add-on boards. They are intended mainly for the high-margin computer games market. nine0005

The product was later diversified to cover all areas of the PC graphics market, from affordable GPUs pre-installed on motherboards to popular add-on boards. Recently, GeForce technology has been introduced to a wide range of NVIDIA embedded processors for mobile phone and electronic handheld applications.

Choosing a graphics card for CUDA

A higher number of CUDA cores usually means that your graphics card can deliver better overall performance. However, this number is just one of many things to consider when choosing a graphics card. nine0005

NVIDIA has a variety of graphics cards with CUDA cores ranging from 8 (GeForce G100) up to 5,760 CUDA cores such as the GeForce GTX TITAN Z. Pascal, Maxwell, Kepler, Fermi or Tesca architecture graphics cards can support CUDA. .

What are the applications of NVIDIA CUDA and its GeForce GPUs?

CUDA and NVIDIA GPUs have been adopted in various fields with the need to high computing performance . Below is a complete list of their applications.

  • Computing finance
  • Weather, ocean and climate modeling
  • Analytics and Data Science

Part 2.

What is NVIDIA NVENC and how does it work?

NVIDIA NVENC, as you know, is a product developed by NVIDIA since the days of CUDA. This is a very powerful video encoding technology that was introduced with the NVIDIA GeForce 600 series GPU in 2012. Compared to CPU- or CUDA-based video encoders, NVENC is based on CUP and can provide much higher quality video encoding. nine0005

What are NVIDIA NVENC applications?

#1 Accelerated NVIDIA NVENC for H.264/AVC Encoding

Most people are unfamiliar with NVIDIA NVENC and don’t know that it is a necessary technology for today’s people. Most of the TV shows and series you can download, including online streaming sites (like YouTube) and Blu-ray movies, use the H.264/AVC video encoding technology implemented by NVIDIA NVENC.

Over the years, H.264 was the most efficient compression method for . With low bitrate requirements and wide availability, this technology has found its way into all movie playback devices. The H.264 video encoding method was unmatched for a long time.

H.264 processes frames using so-called macroblocks. These are 16×16 pixels that allow for further segmentation. Simply put, it allows you to reduce bitrate more efficiently than older standards while maintaining the same video quality. nine0005

#2 NVIDIA NVENC acceleration for H.265/HEVC

Although H.264 is still extremely popular among users and widely used, it is not the most recommended encoding method currently in use. H.265, also known as HEVC or High Efficiency Video Coding, provides a much higher standard than its predecessor at similar settings.

This means that if you want the same video quality for H.264 viewing, you only need 50% bitrate. Let’s say we recorded a video using H.264 encoding at 60 fps, 15,000 bitrate and very high quality, giving us a file size of 265MB. While our video will certainly look amazing, you can use H.7,500/HEVC encoding to achieve exactly the same results at only 250 bits. Another good thing is that the video size can be reduced to 100 MB. nine0005

Tip: If you want to know how to resize video files so that you can use them in the respective situation you are facing, just follow this link to know more details.

How does NVIDIA NVENC work?

Both H.265 and H.264 use motion compensation prediction by searching for irrelevant areas in one or more consecutive frames. When a non-essential region or region is determined, the encoding procedure refers to another region within those frames. Simply put, when two areas on the same frame are the same (for example, a yellow wall is about 75% of the frame), then these two similar areas are considered as one. nine0005

It was previously mentioned that in the case of H.264, areas can have a maximum size of 16×16 pixels. There is a huge difference here, as HEVC allows you to identify areas with pixel sizes that can be up to 64×64. HEVC also encodes much more efficiently due to its variable block size extended segmentation. This means that the shape of the area is not limited to square blocks.
