 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 will experience. For example, there might be cases when pushing the highest video quality isn't a top priority or you may want to limit the video bandwidth usage in the application. To support this, you can use the Video Constraints API to have tighter control 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
 
-Currently ACS supports setting the maximum video resolution that a client will send. The maximum resolution is set at the start of the call and is static throughout the entirity of the call. The sender max video resolution constraint is supported on Desktop browsers (Chrome, Edge, Firefox) and when using iOS Safari mobile browser.

 > [!NOTE]
 > Video Constraints is currently supported only for our JavaScript / Web SDK, and is available starting in version [1.11.0-beta.1](https://www.npmjs.com/package/@azure/communication-calling/v/1.11.0-beta.1) of the Calling SDK.
 
 > [!NOTE]
 > Future versions of the Video Contraint API will allow enhanced ability by giving control to set the maximum FPS and bitrate, as well as the ability to enforce the video constraint at different points of a call (and not just at the start of a video call).
 
-## Using Video Constraints
-The video constraints setting is implemented on the `Call` interface. To use the Video Constraints, you can specify the constraints from within CallOptions when you make a call, accept a call, or join a call. You will also have to specify `localVideoStreams` in `videoOptions`. Do note that constraints doesn't work if you join a call with audio only option and turn on the camera later.

 With sender max video resolution constraint, you can limit the max video resolution of the sending stream. The value you have to provide for this constraint is `height`.
