How good is Intel Quick Sync?

How good is Intel Quick Sync?

Like most desktop hardware-accelerated encoders, Quick Sync has been praised for its speed. A 2012 evaluation by AnandTech showed that QuickSync on Intel’s Ivy Bridge produced similar image quality compared to the NVENC encoder on Nvidia’s GTX 680 while performing much better at resolutions lower than 1080p.

Which Intel has Quick Sync?

Quick Sync hardware transcoding is available on the following hardware: 3rd Generation (or later) Intel® Core™ processors. Intel® Core™ M processors. Selected SKUs of Intel® Celeron™, Intel® Pentium™ and Intel® Atom™ processors with Intel HD Graphics supporting Intel® Quick Sync Video.

What is DXVA2 copy back?

DXVA2 implementations: native and copy-back The video renderer must also support DXVA, which gives less freedom in the choice of renderers. With copy-back implementation, the decoded video is copied from GPU memory back to the CPU’s memory.

Does Quick Sync use GPU?

Intel Quick Sync is Intel’s version of dedicated video encoding and decoding hardware core. Rather than using a general GPU, this core is located on the processor die and is dedicated just for video processing. Studio will automatically detect if you have the proper hardware or not.

Is NVENC faster?

265 encoding, the VCE and NVENC hardware encoders are considerably faster than the x265 software encoder, at the expense of some quality loss.

Does i7 6700K have Quicksync?

The i7-6700K has Intel Quick Sync but the GTX 970 doesn’t encode with hardware encoding.

Does Xeons have Quicksync?

None of the Intel® Xeon® Processors E5 support Intel® Quick Sync Video.

How do I know if I have Intel Quick Sync?

Go to the product specifications site and choose the processor family then drill down the the exact processor(s) you’d like to check.

1. Look under Processor Graphics section to see if enabled with Intel® Quick Sync Video.
2. If the Intel® Quick Sync Video is set to No- The processor does not support the feature.

Does VLC use GPU?

Introduction. The VLC media player framework can use your graphics chip (a.k.a. GPU) to accelerate decoding of video streams depending on the video codec, graphic card model and operating system. In some cases, it can let the graphic card perform post-processing and rendering of the decoded video.

How do I test my Dxva?

1. Report Ad. The developer has also included Decoder Device Creator feature, which you can access by clicking Device Creator under Decoder Device tab.
2. Report Ad. Processor Device tab lets you check whether your CPU supports DXVA technology or not, the same way as we checked under Decoder Device tab.
3. Report Ad.
4. Report Ad.

Do Xeon processors have Quicksync?

Does NVENC reduce FPS?

As you can see, NVENC has the least impact on performance at 60 FPS output. If you reduce the streaming frame rate from 60 to 30, streaming without skipped frames is possible with the faster preset, but from almost no more.

Which is better for decoding native DXVA or QuickSync?

In general, using the QuickSync decoder results in a higher power consumption because the decoded frames are copied back to the DRAM before being sent to the renderer. Using native DXVA decoding, the frames are directly passed to the renderer without the copy-back step.

Which is better Intel QuickSync or cuvidia copy back?

According to LAV Filters author, CUVID and Intel QuickSync are outdated, DXVA copy-back (direct mode) beats them both in performance. DXVA2 native has its limitations, though I use it sometimes with interlaced video cause PCI bus is too busy with traffic for copy-back in this case. DXVA2 native works best for me.

Which is better for gaming cuvidia or dxva2?

DXVA2 native works best for me. CUVID is suggested for Nvidia cards but I still find DXVA2 to be superior with my card. Just turn off hardware deinterlacing as it destroys the quality on SD sources. Default is generally a safe choice and it does deliver ~1% CPU usage.

Which is more efficient QuickSync decoding or interlaced VC-1?

The odd-man out in the power numbers is the interlaced VC-1 clip, where QuickSync decoding is more efficient compared to ‘native DXVA2’. This is because there is currently no support in the open source native DXVA2 decoders for interlaced VC-1 on Intel GPUs, and hence, it is done in software.
