# Color space versus video resolution
<a name="color-space-vs-resolution"></a>

Color space refers to the range of color. MediaLive supports the following color spaces:
+ SDR (standard dynamic range)
+ HDR (high dynamic range) color spaces

Resolution refers to the video pixel count. MediaLive supports the following resolutions:
+ SD (standard definition).
+ HD (high definition).
+ UHD (ultra-high definition). For UHD, MediaLive resolutions up to 4K.

The following combinations of color space and resolution are typically used:
+ SDR color space can be associated with SD, HD, and UHD video.
+ HDR color space can be associated with HD or UHD video. 

An HDR color space isn't typically associated with SD content, but MediaLive *does* support ingesting this combination.
