In-stream video in DCM
In-stream video (also know as pre-roll) allows advertisers to place video ads in video content that's streamed online. It may include the following elements:
- Pre-roll video (required): A digital video (often a 15- or 30-second TV spot) that plays in a website's video player before or in the middle of content.
- Companion banner (optional): A banner that displays on the webpage while the pre-roll video is playing and remains on the page after the video has completed. Some sites support multiple companion sizes.
Use DoubleClick Campaign Manager (DCM) to upload and serve in-stream video creatives. Learn more in the DCM Help Center.
