for the past 48 hours I tried to crop the black bars of a 2048x1152 (16:9) video to a 1.85:1 aspect ratio (which is 2048x1107) so that the encoded video shows exactly what is meant to be.

First problem: 2048x1107 (1.85:1) is not common but is it basically possible to create? Can i encode with libx264 with an odd number value like 1107?

Second problem: If not, how can I make a crop & resize encode in one sitting? Means... Cropping 2048x1152 (16:9) to 2048x1107 (1.85) AND resizing the 2048x1107 (1.85, uncommon) to 1998x1080 (2K DCP FLAT)

I only manage to get a 1998x1080 (1.85:1) with too much cropped on all sides... :/

Thanks for you help, guys!

You can carry out the changes in one command by chaining the respective filters.

Basic syntax is

ffmpeg -i input -vf "crop=2048:1107:exact=1,scale=1998:1080,setsar=1" -c:a copy out.mp4
