I have tried creating the proxy from:
1 – right clicking on the comp in the project window choosing > Set Proxy > Movie…
2 – opening the comp in the timeline, and choosing Composition > Pre-render…
I will try adding to render queue and choosing Set Proxy. I wasn’t aware that this was an option! Thanks!
