SVT VP9 encoder. Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel® Xeon® processors. Using the open source SVT-VP9 encoder, it is possible to spread video encoding processing across multiple Intel® Xeon® processors to achieve a real advantage of processing efficiency.
The Scalable Video Technology for VP9 Encoder (SVT-VP9 Encoder) is a VP9-compliant encoder library core. The SVT-VP9 Encoder development is a work-in-progress targeting performance levels applicable to both VOD and Live encoding/transcoding video applications.
The SVT-VP9 Encoder is being optimized to achieve excellent performance levels currently supporting 10 density-quality presets (please refer to the user guide for more details) on a system with a dual Intel® Xeon® Scalable processor targeting:
SVT-VP9 Encoder also supports 3 modes:
A visually optimized mode for visual quality (-tune 0)
An PSNR/SSIM optimized mode for PSNR / SSIM benchmarking (-tune 1 (Default setting))
An VMAF optimized mode for VMAF benchmarking (-tune 2)

SVT-VP9 Encoder may run on any Windows* or Linux* 64 bit operating systems. The list below represents the operating systems that the encoder application and library were tested and validated on:
Windows* Operating Systems (64-bit):
Linux* Operating Systems (64-bit):
The SVT-VP9 Encoder library supports the x86 architecture
In order to achieve the performance targeted by the SVT-VP9 Encoder, the specific CPU model listed above would need to be used when running the encoder. Otherwise, the encoder runs on any 5th Generation Intel® Core™ processor, (Intel® Xeon® CPUs, E5-v4 or newer).
In order to run the highest resolution supported by the SVT-VP9 Encoder, at least 10GB of RAM is required to run a 4k 8bit stream multi-threading on an 8180 system. The SVT-VP9 Encoder application will display an error if the system does not have enough RAM to support this. The following table shows the minimum amount of RAM required for some standard resolutions of 8bit video per stream:
| Resolution | Minimum Footprint (GB)| |-----------------------|-----------------------| | 4k | 10 | | 1080p | 4 | | 720p | 3 | | 480p | 2 |
