How do you export only the active 2.39:1 image from a 16:9 timeline in Resolve?
I've got a 16:9 project where I've overlaid letterboxing to achieve a 2.39:1 frame. So the active image area is 3840x1608 inside the letterboxing, while the timeline resolution remains 3840x2160.
I'm trying to export only the active 3840x1608 image area from the Deliver page using a custom resolution, but it's exporting incorrectly with black borders around the image.
I'm trying to avoid changing the timeline resolution to 3840x1608 because it affects how certain effects like vignetting behave/look.
Any advice on the proper workflow for this?
EDIT: The letterboxing is created using an adjustment clip cropping the top and bottom over the entire timeline.
