Can I change an already recorded video on my iPhone 11 into a time lapse?

Hey there grandmahazel,

We understand you'd like to change a recorded video into another format.

You would need to have the time-lapse mode selected at the time of recording the video. Learn more about camera modes here: Use camera modes on your iPhone, iPad, and iPod touch

Cheers!

Hello,

Yes, you can convert your videos through the Apple video editor iMovie > https://apps.apple.com/us/app/imovie/id377298193.

It will have a similar effect and works great!

Let me know if you manage.

Cheers
