I’m having a similar problem. Even when I set auto render to render all open sequences, and leave the computer idle for way longer than the number I have set, it’s only rendering the active sequence. I have the other two unrendered sequences in the timeline, but they’re not active. I’m assuming that “Render RT segments” should be checked if I want segments that are already playable in real-time to be rendered fully. Still nothing. Is there something I’m missing?
Thanks a tip I picked up here, it may be a moot issue. If I had three sequences each with an hour render, I previously had to come back to it after each one rendered to start the next. I was hoping auto render would solve that issue, but it turns out I can select them in the browser window and select render to have FCP do them all. I’d still like to troubleshoot and understand this one.
