What is QSV? Advantages of Using QSV Encoding Technology

Intel Quick Sync Video (QSV) is a feature integrated into some Intel CPUs that accelerates video encoding and decoding. It offloads these tasks from the main processor, allowing for faster and more efficient video processing. This technology is particularly beneficial for tasks like video editing, streaming, and converting video formats.

Some of the main benefits of QSV encoding when used appropriately include:

  • Greatly accelerated video conversion/transcoding speeds
  • Reduced CPU usage for more efficient multitasking
  • Support for various video codecs (H.264, HEVC, VP9, AV1, etc.)
  • Wide compatibility with many video editing and streaming programs

In a nutshell, if you have an eligible Intel Core processor, you can also enjoy hardware-accelerated and energy-efficient video processing.

Is My Intel Processor Qualified for QSV Encoding?

Contrary to popular belief, you have to know that Intel Quick Sync Video is not available on every Intel processor. Most modern Intel CPUs aimed at consumers support QSV, but functionality can vary between processor tiers and generations. It's important to verify your specific CPU model for full QSV capabilities. Here's the walkthroughs for Windows 10 or 11:

Step 1. Right-click on your "Windows Start" menu and open "System" option to determine your processor model.

Step 2. Go to Intel Official Product Specifications page and type in your model ID in the search box.

Determine Your Intel Processor Model

Step 3. Open the specification page of your processor model, scroll down and navigate to "Intel® Quick Sync Video" section.

Step 4. If it shows "Yes", it means your processor is qualified for Quick Sync Video encoding.

Tips. A quick check with tools like CPU-Z can reveal if your processor supports QSV as well.

Step 1 - Enable the Hardware Acceleration Option

Install and runInstall and run HD Video Converter Factory Pro. Open “Converter”, and it will automatically scan your hardware to check if it supports Intel QSV acceleration for the first time using the QSV-enabled application.

If not, click the "Intel" logo in the lower right corner to check it out. A dialog box will appear and tell you which profiles support QSV H.264 and H.265/HEVC encoding.

The QSV encoder enables the GPU acceleration by default, you can also open "Hardware acceleration" window and manually enable the feature.

Step 2 - Add Video Files

Click "Add Files" to import the video files you want to convert. To make it easier, just perform a drag-and-drop action. It supports nearly all common and unpopular video file types.

Add Video Files to Intel QSV Encoder

Step 3 - Select an Export Format

Open the full list of 500+ predefined presets on the right side and select one profile that supports QSV encoding.

For example, you're recommended to go to "Video" category and select "H.264" profile for QSV H.264 encoding or "H.265 for MP4" for QSV H.265 encoding.

Select an Output Format for Intel Quick Sync Video Encoding

Step 4 - Start Intel QSV Encoding

Choose a destination to save the output video files. Finally, hit "Run" to start QSV accelerated encoding process.

The more powerful the CPU performance, the more obvious the QSV hardware acceleration, and the higher the conversion efficiency.

My CPU Supports QSV, Why Can't I Enable the Acceleration?

If your processor model supports Intel® Quick Sync Video but the QSV encoder still shows "The graphics card does not support Intel QSV acceleration.", you can try to troubleshoot the issue as follows:

1. Make sure the BIOS is the latest version for the motherboard.

2. Make sure you enable the Intel Graphics card in BIOS.

3. Update the graphic drivers to the latest version.

4. For a computer equipped with two GPUs, force display on Intel® HD Graphics output.

5. Try another QSV-enabled application like HandBrake and see if it works well.

Final Words...

Intel Quick Sync Video technology has transformed the realm of video encoding, providing an efficient, fast, and quality-maintaining solution. It is particularly invaluable for professionals in video production and content creators who require swift processing times. The HD Video Converter Factory Pro, with its QSV compatibility, stands as a testament to how technology can streamline and enhance video encoding processes. Cheers!
