### Limitations


Be aware of the following limitations:

- The video unit price for a screen sharing stream is based on the **video resolution** you set in `ScreenCaptureParameters`. If you do not pass dimensions in `ScreenCaptureParameters`, <Vg k="COMPANY" /> bills you at the default resolution of 1920 x 1080 (2,073,600). See [Pricing](../overview/pricing) for details.

After you set the resolution and frame rate, the SDK automatically sets the corresponding bitrate. Agora does not recommend that you modify the bitrate manually.

Use the `setVideoEncoderConfiguration` method to configure video encoding parameters.
You can call this method at any point after initialization, whether it's before or after joining a channel. For optimal performance, best practice is to enable the video module by calling `enableVideo` before calling `setVideoEncoderConfiguration`. This approach reduces the time required for the first frame to be generated.
Use the `setVideoEncoderConfiguration` method to configure video encoding parameters. You can call this method before `enableVideo` to speed up the time for the first frame to appear. Alternatively, you can call this method within the channel to flexibly adjust video encoding properties.

To set video encoder configuration, refer to the following code:

```java

Log.e("Field", "Can not find field " + dimension.getSelectedItem().toString());
} catch (IllegalAccessException e) {
