Description
Similar but not identical to bug #T2073, when I render, the previewer should reflect what is being rendered, at least the resolution/aspect ratio of the render settings. Currently, if I put in a render resolution of 640x360 (same aspect ratio as my source video, and ends up rendered with no letterbox bars), the aspect ratio is kept at 4:3 during the render "realtime preview" and I see letterboxing.
