Instagram is testing Templates, a new feature that will allow Reels creators to use the same format as other videos, according to Business Insider.

The feature is currently only available to a small group of creators and is in beta testing. It’s similar to TikTok’s Templates, which allows users to plug in their own photos into a preset format.
