Hey, great post!

On Insta-stories, you can upload a video from your camera roll. The constraint is that you have to make the video within the last 24 hours.

Which means; you can upload on the go and pre-made video!!

This is a major point of difference between IG and Snapchat as a brand, one is about brand/personality cultivation and the other continues to be raw and authentic.
