Hi Cliff
In this installation there are 20 Macs, each running Premiere. There are also 15 servers each running Proxmox + 4 virtual W7 instances, and each of those with Adobe Premiere running too. So capacity for 80 renders.
When a job is edited on one of the Macs, once finished the editor hits a big green button that saves the .prproj to a special folder that reads the file and sends the job to a render farm server. This server determines which one of the machines to send it to (one of the 60 VMs or one of the Macs if they are not being used for editing, and if ProRes is required in the final format). The HBR media is made available to the rendering machine, and the rendering kicked off via some special software. Once finished, the rendered file is added to the MAM system, along with its metadata, or sent off to some other workflow like publishing /distribution/ CDN /OTT according to the job requirements.
It’s a scalable model… so it’s working here with 80 simultaneous renders, but is equally happy with 800 or 8.
Hope that helps…let me know if you need more details.
Mike.
