Thanks for the suggestions.
I’ve now tried enabling “Resize PIE Window to Output Resolution” in the project settings, but unfortunately, that didn’t resolve the issue — the MRQ render still outputs at a resolution 1920*1008, rather than the job’s specified 1920*1080 output resolution.
Also, the sequence was already unlocked via the icon in the top-right
`LogViewport: Scene viewport resized to 1920x1008, mode Windowed.
LogMovieRenderPipeline: Finished setting up rendering for shot. Shot has 1 Passes. Total resolution: (1920x1080) Individual tile resolution: (1920x1080). Tile count: (1x1)`
