You can put a video player in a repeater, but not a video box. The issue then is that you don’t get that seamless and interaction free autoplay. There is no way to turn off hover interactions or the playback bar or even customize it’s appearance. Here’s my workaround:
Insert the the video player and set it to an uploaded video.
Place the video player in a container of the dimensions of your choice and make the video the full size fo the container.
In order to get an overlay free image, put a square the same color as the background of your site thats 60px high and place it in the same container that the video player is in, attached to the bottom of the frame at 100% width. This will fully cover the playback bar but may need to be adjusted per breakpoint
Add another rectangle to the container, and set it to span the entire container. Make the fill of the rectangle 100% transparent. This will prevent the darkening hover effect and remove the ability to click anywhere to pause.
There. Your video will now autoplay in a repeater the same way a video box would. The side effect is that you’re going to have to overcompensate by 60px for every item below the video to avoid a weird line. Also, it doesn’t work if your background is anything but a solid color. Also, for any video upload you’re loosing the bottom 60px which isn’t the biggest deal if you just resize the export video to have 60px of black underneath.
Looking forward to being able to do this a non-janky way.
