How to Run an Ad on Reels: Specs and a 15s Video

To run an ad on Reels, upload a vertical 9:16 video in Meta Ads Manager and choose the Reels placement; Meta's spec page allows MP4 or MOV up to 4 GB, from 0 seconds to 15 minutes, and asks you to keep the top 14% and bottom 35% free of text and logos. Reviral makes the 15-second 9:16 ad from your product photos for 278 credits (~$3.47).

Reel advertising budget and creative

Meta suggests starting with at least $5 and running for more than six days so delivery can learn. The creative is the part you control most: a hook in the first second and the product shown early.

Reviral's 15-second clip leaves room for one hook, one proof moment and the product name; a matching 9:16 picture ad at 1080 x 1920 costs 3 credits (~$0.04) for people who scroll past video.
