Why does my video keep stopping while recording

Hi there suzzy97,

Welcome to Apple Support Communities.

We understand that your video stops while you're recording and you were able to review one of the support articles. Are you using the built-in Camera app? Remove any magnetic attachments you have on iPhone. Make sure you have available storage in Settings > General > iPhone Storage. Check that your iPhone is running the latest software version in Settings > General > Software Update.
