# Video overlay use cases Source: [https://docs.qualcomm.com/doc/80-70015-50/topic/overlay-use-cases.html](https://docs.qualcomm.com/doc/80-70015-50/topic/overlay-use-cases.html) The pipelines show the use cases for video overlay. These use cases use the *dest-rect* property coordinates from the *overlay-mask* property of the [qtioverlay](https://docs.qualcomm.com/doc/80-70015-50/topic/qtioverlay.html) plugin. Before you run the use cases, ensure that you complete the preconditions mentioned in [Multimedia use cases](https://docs.qualcomm.com/doc/80-70015-50/topic/multimedia-use-cases.html). Note: The commands in the following use cases use the 720p resolution. To change the resolution, update the respective *dest-rect* property coordinates in the command for that resolution. For more information, see [qtioverlay](https://docs.qualcomm.com/doc/80-70015-50/topic/qtioverlay.html). - **[User text overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/user-text-overlay.html)** This pipeline overlays text onto a video stream. - **[Date and time overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/date-and-time-overlay.html)** This pipeline shows the date (in MMDDYYYY) and time (in HHMMSS) to be overlaid onto the video stream. - **[Static image overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/static-image-overlay.html)** This pipeline shows how to overlay a static image onto a video stream. - **[Bounding box overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/bounding-box-overlay.html)** This pipeline shows how to overlay a bounding box with a label onto the video stream. - **[Inverse privacy mask](https://docs.qualcomm.com/doc/80-70015-50/topic/inverse-privacy-mask.html)** This pipeline shows how to overlay the inverse privacy mask on the video stream. - **[Non-inverse privacy mask](https://docs.qualcomm.com/doc/80-70015-50/topic/non-inverse-privacy-mask.html)** This pipeline shows how to overlay the non-inverse privacy mask onto the video stream. - **[Polygon privacy mask](https://docs.qualcomm.com/doc/80-70015-50/topic/polygon-privacy-mask.html)** A polygon privacy mask enables you to create privacy zones on an image using a polygonal shape. Using a polygon enables you to make the masking smoother and more accurate. **Parent Topic:** [Multimedia use cases](https://docs.qualcomm.com/doc/80-70015-50/topic/multimedia-use-cases.html) Last Published: Oct 27, 2025 [Previous Topic p live camera and 1080p offline picture-in-picture composition](https://docs.qualcomm.com/bundle/publicresource/80-70015-50/topics/1080p-live-camera-and-1080p-offline-picture-in-picture-composition.md) [Next Topic User text overlay](https://docs.qualcomm.com/bundle/publicresource/80-70015-50/topics/user-text-overlay.md)
