To save a Live Photo as a video on an iPhone or iPad, follow these steps:

1. Open the Photos app and go to your Live Photos album (found under Albums > Media Types > Live Photos).
2. Select the Live Photo you want to convert.
3. Tap the Share button (usually at the bottom left of the screen).
4. Scroll down and tap "Save as Video."

This will save the Live Photo as a video file in your Camera Roll and also in the Videos album. The original Live Photo remains intact in your Live Photos album

. Additional tips:

• You can also swipe up on the Live Photo to access effects like Loop or Long Exposure before saving it as a video.
• If you want to combine multiple Live Photos into a longer video or need more editing options, apps like iMovie or third-party apps such as Movavi Video Editor or Lively can help

• This feature requires iOS 13 or later.

This method is quick and does not add watermarks, making it ideal for sharing your Live Photos as short videos on social media or other platforms
