Video Transcoding

Video transcoding instances are designed to provide real-time video transcoding. These instances are highly suitable for live event broadcasts, video conferencing, and real-time transcoding applications.
These instances are provided by the Virtual Machine service.

• Applicable type: vt1a

vt1a

vt1a instances are powered by 3rd generation AMD EPYC 7003 series processors and are suitable for live video transcoding workloads.

Hardware specifications

• Up to 3.6Ghz 3rd generation AMD EPYC processor (AMD EPYC 7643)
• Up to 50Gbps network bandwidth
• Support for up to 8 Xilinx U30 media accelerator FPGA cards including accelerated H.264/AVC and H.265/HEVC codecs
• Support for resolutions up to 4K UHD
• Support for AMD instruction sets (AVX, AVX2)

Use cases

Live event broadcasting, video conferencing, and real-time transcoding

NUMA topology

In Non-Uniform Memory Access (NUMA) architecture, each CPU can access its own allocated memory (local memory). Using NUMA architecture allows for sharing memory across multiple processors, thus achieving high scalability.

vt1a instances have the following NUMA topology according to the instance size.

Instance size	Number of NUMA domains	Cores per NUMA domain
vt1a.4xlarge	1	8
vt1a.8xlarge	1	16
vt1a.32xlarge	2	32
