Directly Uploaded Video Submissions
The File Upload field in your Photo/Video Contest can accept .mp4 and .mov files (up to 250MB) and directly uploaded videos are now visible/playable in your campaign’s gallery. These files can also be downloaded from your Uploads export. For longer videos or larger file sizes, we recommend the hashtag entry method.
Hashtag Video Submissions
Hashtag video submissions must be entered via hashtag entry on Instagram. Stories or temporary posts are not supported in Photo/Video contests, but Reels and standard posts can be accepted.
When submitted correctly and approved, that video submission will display and be playable in the Gallery.
