Up to 30 frames per second. In the conversation placement video is click to play.
By format the mix is 59.1% image, 26.6% video, 14.3% carousel. Reddit creative is the whole post, so the shape that matters is the one the feed gives it: 1:1 or 4:5.
Make it 4:5 for the mobile feed, where it takes the most screen, and keep a square cut as the shape every placement accepts.
The headline sits above the video in the post's own type. It is the first thing read, and the video plays muted under it.
Image and carousel specs are on Reddit ad specs; real promoted posts are in the Reddit ads library.
