ASPECT RATIO
OVERRIDE.

What does this mean? Lately it had something like "let the system determine ratio". Now that seems to be gone.

Why is there not a format ratio selection for 4K DCI?

DCI is a more formal and easy to understand to the industry. It's actually 1.90:1 or 256:135 which is close to 17:9. There are several standards. HD, UHD, 2K and 4K DCI. These all have an exact definition and meaning. 16:9 or 17:9 ratio are really not needed. Make the choices: HD, 2K, UHD, 4K DCI,

Sooo now does "4K+other" mean UHD and DCI?
