Tom, the 7sec round trip latency does seem a bit high, though we would need to understand the complete end-to-end system path, and how the latency is measured.
AWS MediaLive, by default will not be configured for a low latency encode. You can typically expect 3-4s, depending on source, output resolution, bitrate and other parameters. There are changes to the MediaLive Channel that can be made to reduce the encoding delay, yet achieving <500ms is unlikely. MediaLive is not targeted as an ultra low latency encoder.

Mike - thanks very much for your swift reply.
There is defo some latency introduced in our testing pipelines, so the figure you shared of 3-4s seconds makes sense overall.
Do you know if there is a ultra-low-latency encoding option within AWS services, beyond resorting to GPU-enabled EC2 instances to run our in-prem workflows?
Thanks
