You'll get black bars (or whatever the background color is) as padding on the sides to force the inner video elements into the desired aspect ratio

When using `&locked`, the default aspect ratio is 16:9, but you can pass a floating point value for different aspect ratios, or use `landscape` (instead of `1.77777`) / `portrait` / `square` as presets if needed.

Padding is centered, so the rendered video will be in the center of the screen. (tho using [`&widget`](https://docs.vdo.ninja/advanced-settings/settings-parameters/and-widget) mode might break things though).

This `&locked` option is added to the [Mixer App](https://docs.vdo.ninja/steves-helper-apps/mixer-app)'s WHIP/**Twitch publishing output option**, so regardless of window size, you'll get a 16:9 video render.
