# Resolution A `Resolution` is a setting defined by a string. It is mapped to a size measured in pixels according to special rules. You may use it, for example, to change the resolution of a video captured by a webcam, to adjust the resolution of a video when it is processed by a tracker, or to set the rendering resolution of a virtual scene. The table below shows examples of how resolution strings are converted to pixels: | Resolution | 16:9 | 16:10 | 4:3 | Notes | | ---------- | ---- | ----- | --- | ----- | | `"xs"` | 214x120 | 192x120 | 160x120 | | | `"xs+"` | 256x144 | 230x144 | 192x144 | 144p | | `"sm"` | 426x240 | 384x240 | 320x240 | 240p | | `"sm+"` | 512x288 | 460x288 | 384x288 | | | `"md"` | 568x320 | 512x320 | 426x320 | | | `"md+"` | 640x360 | 576x360 | 480x360 | 360p | | `"lg"` | 854x480 | 768x480 | 640x480 | 480p | | `"lg+"` | 1066x600 | 960x600 | 800x600 | | | `"xl"` | 1280x720 | 1152x720 | 960x720 | 720p | | `"xl+"` | 1366x768 | 1228x768 | 1024x768 | | | `"xxl"` | 1600x900 | 1440x900 | 1200x900 | | | `"xxl+"` | 1706x960 | 1536x960 | 1280x960 | |
