Q: video option disappeared on iphone5s and iphone6

Greetings preciousjas,

Welcome to the Apple Support Communities!

I understand that several options in your Camera app, including Video, appears to be missing. To troubleshoot this situation, I would suggest following the first three steps in the attached article below. This article was written to troubleshoot apps downloaded from the App Store, but these first three suggestions, Restart the app, Restart your device, and Check for iOS and app updates are still relevant to your situation. 

If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support

Cheers
