## Definition

`--ar 16:9` is a parameter passed to an image-generation model (Midjourney) that requests output with a **16:9 aspect ratio** — a widescreen image sixteen units wide for every nine units tall, matching standard video dimensions.

>`--ar 16:9` is an **aspect-ratio parameter** used when prompting an image generator: the `--ar` flag tells the model to produce output at a **16:9 width-to-height ratio** — the widescreen shape of standard video frames and film stills. A ratio of 16:9 means the image is sixteen units wide for every nine units tall, so anything generated with this flag comes out landscape-shaped rather than square or vertical.\<> >In the channel's creative-workflow material, image generation with **Midjourney** is the step that produces the still frames that get animated downstream — the filmmaker's pipeline described here moves from rough idea, to generated images, to animated clips in a tool like Runway.[^388e44bb-d2fd-5125-96b6-db41535d503d@0] Because the final destination is a **video frame**, a widescreen shape is the natural target, which is exactly the shape `--ar 16:9` requests. Choosing the aspect ratio at the image-generation stage means the frames fit their destination without cropping or letterboxing later.\<> >>\`--ar` sets the **width-to-height ratio** of the generated image; `16:9` is the widescreen ratio standard for video.\>\The flag is written directly in the **prompt** to the image model (e.g., Midjourney in this channel's pipeline).\>\Setting aspect ratio at generation time keeps frames **matched to the video format** they will become.\>>>
