Banner videos should be shot specifically to fit the WCMS banner area: 1800x600 (3:1). Note: Most videos aren’t shot at 3:1, which is why banner footage needs to be shot very intentionally.
Banner videos do not have audio and do not require closed captioning; however, a transcript is still required.
Banner videos require .mp4 and .webm files to be uploaded to the WCMS, and may not be hosted on external sites. Banner videos also require a fallback image and a mobile image.
For optimum speed, the banner image file size should be no larger than 2MB. Although there is a 30 second maximum for video banners, the more content you have on the page (a lot of text, big images, etc.) the more likely your page load and video speed will be affected. Videos should be no longer than 15 seconds.
