Got handed a pile of stock footage downloaded from various sites. And found one clip is 4k ( 4096x2160)
I put it into AME to reexport it as DNx115 but when I set it to 1920x1080 23.976 I see letterboxing top and bottom. It says the source clip pixel ratio is 1 and mine is 1.. tried the others for kicks but none get rid of it.
Why am I getting letterbox for this conversion?
