At WhatsApp, privacy is our DNA. That’s why we rolled out end-to-end encryption in 2016 — so that when messages are end-to-end encrypted, only you and your intended recipients can see the messages you send.

Instead of sending the entire video at once, a video is sent as a set of smaller chunks that make up the full video.
