Me too! I look all around and didn’t find a way to mix videos and photos.
The workaround of the repeater and a radio checkbox to select video or image… couldn’t make it work.
I see that the gallery field allows loading video, but can’t figure out how to output them. i can only see the images, and the blank space with the url of the video, when I click on it, it just says “the image could not be loaded”.
