Quicksync h.264 how to#
How to enable Intel Quick Sync Video encoder Basically x264 is rendered on the general purpose cores of your CPU while Quicksync uses a dedicated core on your (intel-)CPU. Studio will automatically detect if you have the proper hardware or not. Rather than using a general GPU, this core is located on the processor die and is dedicated just for video processing. Intel Quick Sync is Intel’s version of dedicated video encoding and decoding hardware core. By default, this is set to “Very Fast”, which provides the best balance between performance and quality. The faster it encodes, the less CPU it uses. The usage preset refers to how fast the CPU encodes video. If you’re recording and need to be high quality, use CQP if the file size is no issue, or VBR if you want to keep file size more reasonable.
If you’re streaming, use CBR as every platform recommends it and it’s a reliable form of Rate Control. Which encode better : x264 many people say still good but I heard it will stress the Cpu. 265/HEVC supports resolutions up to 8192×4320, which includes 8K UHD as well. 264, this newer standard offers from 25% to 50% better data compression at the same level of video quality. Processor needs to be Intel Core 2 Duo, AMD Athlon X2 or better.Ģ65 is a video compression standard that was designed for the newest generation of high-resolution video.

HandBrake can be running on Linux, Mac and Windows using GPU acceleration, but there are system requirements. If the Intel® Quick Sync Video is set to No- The processor does not support the feature.Īnswers: 1.Look under Processor Graphics section to see if enabled with Intel® Quick Sync Video.Go to the product specifications site and choose the processor family then drill down the the exact processor(s) you’d like to check.

All load goes to this gpu while you may still use your AMD/Nvidia GPU at full power. I suppose I could manually configure my topology, but as I will be using this application on a variety of systems, I am not guaranteed to have one particular topology.QuickSync uses your Intel processors graphics chip to do the encoding. I could not figure out what this means after a good deal of searching, or how to provide the correct parameters for this to be overcome. Selected as the encoder, per the following line from the mftrace output:ġ0836,295C 18:26:33.47371 CMFPlatExportDetours::MFGetMFTMerit Merit validation failed for MFT (hr=80004005 E_FAIL) Hardware transforms by setting the MF_TRANSCODE_TOPOLOGYMODE_HARDWARE_ALLOWED attribute in the video encoder profile, I saw in the mftrace dump that the Intel Quick Sync Video H.264 Encoder showed up during encoder enumeration. I am trying to switch over to a hardware H.264 encoder, due to poor frame rate in the resulting file. This currently works at the moment, despite some issues with playback and incorrect metadata. Sandy Bridge and Ivy bridge has lower quality H264 Quicksync while Haswell+ has better quality.
But that depend on what version of Quicksync are you using too. 1 Version 4 ( Broadwell) The Broadwell microarchitecture adds VP8 hardware decoding 9 support. x264 at ultrafast-superfast can be worse than Quicksync3. This generation of Quick Sync supports the H.264/MPEG-4 AVC, VC-1 and H.262/MPEG-2 Part 2 video standards. USB Webcam -> MJPEG Decoder -> Color Converter DMO -> My Custom MFT (RGB32 in/out) -> Color Converter DMO -> Microsoft H.264 Encoder -> MPEG4 Sink x264 veryfast will give close or a bit better to H264 Haswell Quicksync quality. I have developed an application which uses the MF Media Session architecture with the following topology:
