Is 2: 1 frame ratio suitable for feature film shooting?

Divide the picture into two parts with the ratio of 2: 1, forming a left-right echo or an up-and-down echo, and the performance space is relatively broad. One part of the picture is the subject and the other half is the partner. Often used to express people, sports, scenery, architecture and other themes.

The change of the scale of the picture can enhance the sense of space and depth of the picture, and can also convey the theme and intention that the photographer wants to express more accurately.
