Our target users don't have much experience with mobile apps and are familiar with Whatsapp or couple more apps at max. So, I've been thinking of showing 'how to use app' video(gif) during the splash screen. A non-audio based gif playing repeatedly when the app starts until the user taps on Get started. 

What are your thoughts on this? 

And is anyone already using something like this? I've seen videos(/gifs) at start but they're not the same... They don't explain what the app is about and how it actually works.

Note: I'm planning to introduce a 10-12 sec gif. More than that would be too much I guess...
