To add video to a creative you're building with Google Web Designer, drag either the Video component or the YouTube component to the stage.
If your video is hosted on YouTube, use the YouTube component .
If you want to use a MP4, OGG, OGV, or WEBM video file, use the Video component . If your file is a different format, you can either use video editing software to export it into one of these formats, or upload it to YouTube and use the YouTube component instead.
