Intel Quick Sync Video

{{short description|Video encoding and decoding hardware by Intel}}

Intel Quick Sync Video is Intel's brand for its dedicated video encoding and decoding hardware core. Quick Sync was introduced with the Sandy Bridge CPU microarchitecture on 9 January 2011 and has been found on the die of Intel CPUs ever since.

The name "Quick Sync" refers to the use case of quickly transcoding ("converting") a video from, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone, in situations where speed is more important than the best possible quality.

Unlike video encoding on a CPU or a general-purpose GPU, Quick Sync is a dedicated hardware core on the processor die. This allows for much more power-efficient video processing.{{cite web |url=http://www.tomshardware.com/reviews/sandy-bridge-core-i7-2600k-core-i5-2500k,2833-4.html |title=Intel's Second-Gen Core CPUs: The Sandy Bridge Review - Sandy Bridge's Secret Weapon: Quick Sync |date=3 January 2011 |publisher=Tom's Hardware |access-date=2011-08-30}}{{cite web |url=http://www.anandtech.com/show/4083/the-sandy-bridge-review-intel-core-i7-2600k-i5-2500k-core-i3-2100-tested/8 |title=The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested |publisher=AnandTech |access-date=2014-04-05}}

Availability

Quick Sync Video is available on Core i3, Core i5, Core i7, and Core i9 and new Core Ultra processors starting with Sandy Bridge, and Celeron & Pentium processors starting with Haswell.{{Cite web |author1=Kevin Parrish |date=2014-02-27 |title=Intel Drivers Bring Quick Sync Video to Pentium, Celeron |url=https://www.tomshardware.com/news/intel-drivers-quick-sync-video-pentium-celeron,26133.html |access-date=2022-11-29 |website=Tom's Hardware |language=en}}{{cite web |url=https://downloadmirror.intel.com/29312/eng/ReleaseNotes_15.36.38.5117.pdf |title=Release Notes Driver version: 15.36.38.5117 |date=2020-01-10 |access-date=2020-01-10}}

Performance and quality

Like most desktop hardware-accelerated encoders, Quick Sync has been praised for its speed.{{cite web|url=http://www.anandtech.com/show/4083/the-sandy-bridge-review-intel-core-i7-2600k-i5-2500k-core-i3-2100-tested/8|title=The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested|access-date=2011-09-23|publisher=Anandtech}} The eighth annual MPEG-4 AVC/H.264 video codecs comparison showed that Quick Sync was comparable to x264 superfast preset in terms of speed, compression ratio and quality (SSIM);{{cite web |url=http://www.compression.ru/video/codec_comparison/h264_2012/ |title=Eighth MPEG-4 AVC/H.264 Video Codecs Comparison. |pages=135–137 (6.4 Speed/Quality Trade-Off) |publisher=MSU Graphics & Media Lab (Video Group)}} tests were performed on an Intel Core i7-3770 (Ivy Bridge) processor. However, Quick Sync could not be configured to spend more time to achieve higher quality, whereas x264 improved significantly when allowed to use more time using the recommended settings.

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.

Development

{{Main|Intel Graphics Technology#Capabilities (GPU video acceleration)}}

Quick Sync was first unveiled at Intel Developer Forum 2010 (September 13) but, according to Tom's Hardware, Quick Sync had been conceptualized five years before that. The older Clarkdale microarchitecture had hardware video decoding support, but no hardware encoding support; it was known as Intel Clear Video.

; Version 1 (Sandy Bridge)

: Quick Sync was initially built into some Sandy Bridge CPUs, but not into Sandy Bridge Pentiums or Celerons. It adds H.264/AVC encoding and VC-1 decoding acceleration.{{cite web |url=http://ark.intel.com/products/53480/|title=Intel Pentium Processor G620}}

; Version 2 (Ivy Bridge, Bay Trail)

: The Ivy Bridge microarchitecture included a "next-generation" implementation of Quick Sync.{{cite web |url=http://www.anandtech.com/show/4318/intel-roadmap-ivy-bridge-panther-point-ssds |title=Intel's Roadmap: Ivy Bridge, Panther Point, and SSDs |publisher=Anandtech |access-date=2011-08-30}}

; Version 3 (Haswell)

: The Haswell microarchitecture implementation adds H.262/MPEG-2 Part 2 encoding acceleration. An open-source hybrid driver was developed which supports partial VP8 encoding and VP9 decoding acceleration under Linux by utilizing both the integrated GPU and CPU.{{cite web| url=https://aur.archlinux.org/packages/intel-hybrid-codec-driver/| title=AUR (en) - intel-hybrid-codec-driver| website=AUR| date=16 July 2017| access-date=10 September 2022| archive-date=12 December 2022| archive-url=https://web.archive.org/web/20221212203419/https://aur.archlinux.org/packages/intel-hybrid-codec-driver| url-status=dead}}{{cite web |url=https://github.com/intel/intel-hybrid-driver | title=intel/intel-hybrid-driver | website=GitHub| date=27 August 2014}} Started from Haswell, Pentiums and Celerons have included QSV technology.{{cite web |url=https://ark.intel.com/content/www/us/en/ark/products/83538/intel-pentium-processor-g3250-3m-cache-3-20-ghz.html | title=Intel Pentium Processor G3250 3M Cache 3.20 GHz Product Specifications }}

Operating system support

The Quick Sync Video SIP core needs to be supported by the device driver. The device driver provides one or more interfaces, for example VDPAU, Video Acceleration API (VA-API) or DXVA for video decoding, and OpenMAX IL or VA API for video encoding. One of these interfaces is then used by end-user software, for example VLC media player or GStreamer, to access the Quick Sync Video hardware and make use of it.

=Linux=

Quick Sync support on Linux is available by both Intel VAAPI Driver (legacy, pre-Broadwell) and Intel Media Driver (Broadwell and newer) which also uses VA-API,{{Cite web |date=2018-08-20 |title=Intel Media For Linux |url=https://01.org/intel-media-for-linux |access-date=2022-09-11 |website=01.org}}{{Cite web |date=2019-01-14 |title=Intel® Video and Audio for Linux* |url=https://01.org/linuxmedia |access-date=2022-09-11 |website=01.org}} and through the Intel Media SDK.

=Windows=

Microsoft offers support for Quick Sync in Windows (in Windows Vista and later) based on supporting driver software from Intel and support through both DirectX as well as WMF (Windows Media Foundation). A wide range of applications are based upon this base support for the technology in Windows.

=macOS=

Apple added Quick Sync support in OS X Mountain Lion for AirPlay, FaceTime, iTunes, Safari, QuickTime X, iMovie, Final Cut Pro X, Motion and Compressor. Third-party software includes Adobe Premiere Pro, Adobe Media Encoder, DaVinci Resolve and others.

Hardware decoding and encoding

Support for Quick Sync hardware accelerated decoding of H.264, MPEG-2, and VC-1 video is widely available. One common way to gain access to the technology on Microsoft Windows is by use of the free ffdshow filter. Some other free software like VLC media player (since version 2.1.0 "Rincewind") supports Quick Sync as well. Many commercial applications also benefit from the technology today, including CyberLink PowerDVD, CyberLink PowerDirector and MacroMotion Bogart "gold" edition.

According to the ffdshow documentation, Quick Sync has very low CPU utilization while being about twice as fast as libavcodec.{{cite web |url=http://ffdshow-tryout.sourceforge.net/wiki/video:codecs |title=H.264/AVC |work=Codecs |publisher=ffdshow-tryout.sourceforge.net |access-date=2011-12-22 |archive-date=2012-09-22 |archive-url=https://web.archive.org/web/20120922233002/http://ffdshow-tryout.sourceforge.net/wiki/video:codecs |url-status=dead }}
