-The Video Constraints API is a powerful tool that enables developers to control the video quality from within their video calls. With this API, developers can set constraints on the video resolution to ensure that the video call is optimized for the user's device and network conditions. The ACS video engine is optimized to allow the video quality to change dynamically based on devices ability and network quality. But there might be certain scenarios where you would want to have tighter control of the video quality that end users experience. For instance, there may be situations where the highest video quality is not a priority or you may want to limit the video bandwidth usage in the application. To support those use cases, you can use the Video Constraints API to have tighter control over video quality.

 Another benefit of the Video Constraints API is that it enables developers to optimize the video call for different devices. For example, if a user is using an older device with limited processing power, developers can set constraints on the video resolution to ensure that the video call runs smoothly on that device
 
-ACS Calling SDK (Web) currently supports setting the maximum video resolution that a client sends. The maximum resolution is set at the start of the call and is static throughout the entire call. The sender max video resolution constraint is supported on Desktop browsers (Chrome, Edge, Firefox) and when using iOS Safari mobile browser.

-ACS Calling SDK (Android/iOS/Windows) currently supports setting the maximum values of video resolution and framerate for outgoing video streams and setting the maximum resolution for incoming video streams. The constraints can be set at the start of the call and during the call.
+The ACS native Calling SDK (Android, iOS, Windows) supports setting the maximum values of video resolution and framerate for outgoing video streams and setting the maximum resolution for incoming video streams. These constraints can be set at the start of the call and during the call.
 
 ## Supported constraints
 
 | Platform | Supported Constraints | 
 | ----------- | ----------- |
-| Web | outgoing video: resolution |
-| Android | incoming video: resolution, outgoing video: resolution \| framerate |
-| iOS | incoming video: resolution, outgoing video: resolution \| framerate |
-| Windows | incoming video: resolution, outgoing video: resolution \| framerate |
+| Web | Outgoing video: resolution, framerate, bitrate |
+| Android | Incoming video: resolution<br />Outgoing video: resolution, framerate |
+| iOS | Incoming video: resolution<br />Outgoing video: resolution, framerate |
+| Windows | Incoming video: resolution<br />Outgoing video: resolution, framerate |
