Have just completed our first run of live streaming events for motorsport using a remote studio rather than having to either build one on site or build a van/bus.

We predominately have been covering motorsport and doing post production for the past 5 years, next year we step into live streaming more often.

After trialling many options we ended up with the following:

3x vMix installs running on AWS (DO NOT use HP Anyware/PCoIP!) - 1 switcher for cameras, 1 producer for final output and 1 director station, unfortunately I've been struggling to find a replay operator, when we find that person we'll have 4 vMix installs in AWS.

1x vMix install running on a laptop at the venue in the commentary booth, this handled the local commentator camera input as well as audio, plus received the remote commentator who was based in Sydney. The audio from both of them was also output to the venue. The delay between what was happening on track in real time, to what the commentators were talking about on their screens wasn't hugely noticeable, plus the local commentator could essentially jump ahead if needed.

4x Cameras around the track sending their feeds via LiveU Solo cloud to a HAIVISION Cloud system, which the vMix instances then accessed for footage.
1x Camera in car running off a KiloView P2
1x Interview camera (Which we only used for a little while but have plans to expand this next year) which had audio going from the hand held mic to the camera, into the stream, and then audio from the camera being fed to the venue.

The stream was all controlled remotely using Streamdecks and Companion on Raspberry Pi.

The stream went out via CASTR to our own website.

I've got a few tweaks to make with the AWS setups such as removing all traces of the HP Anyware/PCoIP system.

This was the result: (slightly cut down to remove a few long delays etc)
