Instagram has deprecated the ability to create a standard video post. Instead all videos posted to Instagram are considered Reels. Due to this change, you won't see the option to select a standard post option when publishing videos to your Instagram account.

Tap Reel at the bottom, then tap the image in the bottom left to open your gallery. Tap Templates. Swipe through the available templates and tap one you'd like to use. Tap Add media, then tap the photos or videos in the order you'd like them to appear.

You can record and edit videos up to 90 seconds with Instagram Reels. You can add effects and music to your reel or use your own original audio.
