Hardware acceleration is used everywhere, from games to graphic design. It is more and more important for video encoding, decoding, compressing and editing. Even Microsoft has added Hardware acceleration support for AV1 video codec to Windows 10.

Without Hardware acceleration, the decoding and rendering of lengthy, RAW files from high-end cinema cameras, and especially 4K Ultra High Resolution videos are often loaded to the brim with stutters, freezes, glitches...

In the text, we will explain in details why VideoProc Converter's full Hardware acceleration boosts (4K) video encoding, editing and rendering to a great extent. But before that, let's learn about the concept, basic knowledge and theory about hardware and GPU acceleration.

The article includes the following parts:

-- Part 1: What Is Hardware Acceleration and GPU Acceleration?

Many users will get confused by the concepts and working principles of hardware acceleration and GPU acceleration or consider they are the same.

Simply put, hardware acceleration is the applying of CPUs (the general-purpose processors) and GPUs / ASICs (fully customized hardware) to improve the efficiency of computing.

GPU acceleration refers to making use of the massive processing power of GPU of, say NVIDA© CUDA™, AMD®, Intel® Core™, and Apple M1/M1 Pro/M1 Max in a parallel way to release the burden of CPU and offload some compute-intensive and time consuming works.

Although hardware acceleration is more extensive, the two have the same purpose, and are widely used to boost gaming, rendering, and image algorithms significantly.

So in the following text, there will be no clear distinction between hardware and GPU accelerations.

Part 2. Hardware Acceleration Is Important to 4K Video Editing

4K resolution brings stunning viewing experiences. But it places high challenges on users' hardware and software, especially on a consumer-level computer.

Listed below are some common problems that can occur during 4K video editing.

Lagging and choppy 4K video playback: If your computer or target device is not capable of playing 4K videos, this issue will be worse.
Decoding & encoding UHD videos is slow and frozen since 4K video is always large in file size.
Lose quality in the editing process: Many video editing applications will auto reduce the resolution or crop the image.
CPU usages jumps to over 90% with overheating computer

Daunted by the challenges with 4K content, many switch to 1080P or 720P, yet still feeling a hankering to gain Ultra-HD experience. GPU acceleration is a make-or-break when it comes to ironing out problems related to 4K content.

GPU deals with graphics processing tasks faster while freeing up CPU to keep all the basic applications run in normal operation. If the software offers no support to GPU acceleration, CPU will drain its last juice to pump power for 4K videos. It easily causes problems.

When VideoProc Converter processes a video (even it is in 4K), the CPU use will remain low. You can let it work like in the background, and do other tasks on your computer at the same time. Transcoding 4K videos will not retard your computer at all. Its full GPU acceleration is most noted in the video conversion. And it promises to keep your original resolution and quality unless you customize it.
