Version 4 ( Broadwell) The Broadwell microarchitecture adds VP8 hardware decoding support.
This generation of Quick Sync supports the H.264/MPEG-4 AVC, VC-1 and H.262/MPEG-2 Part 2 video standards. Version 3 ( Haswell) The Haswell microarchitecture implementation is focused on quality, with speed about the same as before (for any given clip length vs. Version 2 ( Ivy Bridge, Bay Trail) The Ivy Bridge microarchitecture included a "next-generation" implementation of Quick Sync. Version 1 ( Sandy Bridge) Quick Sync was initially built into some Sandy Bridge CPUs, but not into Sandy Bridge Pentiums or Celerons. The older Clarkdale microarchitecture had hardware video decoding support, but no hardware encoding support it was known as Intel Clear Video. 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. Main article: Intel Graphics Technology § Capabilities (GPU video acceleration) Ī 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. However, QuickSync 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. 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) tests were performed on an Intel Core i7 3770 ( Ivy Bridge) processor. Like most desktop hardware-accelerated encoders, Quick Sync has been praised for its speed. Quick Sync Video is available on Core i3, Core i5 & Core i7 processors starting with Sandy Bridge, and Pentium processors starting with Haswell, Celeron processors do not feature Quick Sync Video. 6.1 Hardware video hardware technologies.The bits will increase the usage of your network so always be monitoring the network behaviour in the Stats panel and you can modify it if there in an issue. Here it is the suggested settings for Audio:ĭepending on the selected track, we suggest setting an Audio Bitrate between 128 and the maximum, this to increase the audio quality (if there is a band problem it should be reduced).

If you have a good PC and a bad Internet connection, you can think about rescaling to a lower resolution than the Base to reduce the band usage. To have less workload on your PC keep in mind that you should have the same settings in Video section: the same resolution on Base and Output but if there is a glitch, reduce this resolution on both sides.Īs FPS we suggest something between 24 (speed) and 30 (quality), depending on your hardware. Each encoder has different settings: For NVIDIA NVENC (Preset)

Now you will be wondering how to choose the right one for you.

Apple VT H264 Software Encoder – similar to x264 but has some incompatibility sometime.Apple VT H264 Hardware Encoder – similar to QuickSync.H264/AVC Encoder (AMD Advanced Media Framework) – similar to NVENC.264 – Medium uses i3/4/5 Intel CPU graphic. 264 (new) – Best made for Nvidia RTX cards. Depending of your hardware there will be different options: Under the same Output menu, you will see Encoder. If you do not have hardware that supports hardware transcoding, or you want higher visual fidelity, choose the x264 option. This is because each platform uses different technology to bring streams to life. Choose EncoderĮach online video platforms come with different encoder setting requirements. Enabling hardware encoding will reduce CPU usage, but may result in slightly lower visual fidelity. In the Output Menu (2), select Advanced (3).ĭepending on your computer hardware, you may want to enable hardware encoding.Go to Settings (1) in the main interface.How to setup Output settings in OBSĬhoosing the best encoder configuration is important in order to stream with the best possible quality: It is also important to maintain CPU under 60% and maintain the dropped-missed-skipped frames at the lowest possible.
