fn frame_render_size(project: (u32, u32), target: (u32, u32)) -> (u32, u32)Expand description
Render size for an image export: downscales are rendered straight at the target (the compositor’s
Scaler does the filtering), upscales are rendered at project size and enlarged by ffmpeg with the
chosen resize flag — rendering a 4K frame from a 1080p timeline gains nothing but time.
