The following three methods are supported when selecting the **Capture Method**:

* **Automatic:** Automatically selects between the two methods below based on the PC specifications.

  We recommend this method as it is the most convenient.
* **BitBlt (Windows 7 and up):** A traditional method usable in Windows 10 version 1903 or lower.\
  This method cannot capture frequently used UWP windows, such as Microsoft Office, Chrome, etc.
* **Windows 10 (1903 and up):** Uses **Windows Graphics Capture**, available in Windows 10 version 1903 or higher. This method can capture UWP windows and also supports HDR sources when the **Force SDR** option is unchecked. For more information about HDR live streaming, refer to the page below:
  * [Streaming HDR Content Live on YouTube](/desktop/guides/streaming/youtube-streaming/streaming-hdr-content-live-on-youtube.md)

And, the following three methods are supported when selecting the **Window Match Priority:**

* **Window title must match:** The source is recognized only if a window with the exact same title exists. This option is recommended in most cases.
* **Match title, otherwise find window of same type:** If no window with the same title is found, a similar window is selected based on the class name in Window Attributes.
* **Match title, otherwise find window of same executable:** If no window with the same title is found, another window from the same process is selected.
