Vedio editting lagging

Hi aaiz23,

Welcome to Apple Support Communities. We'd love to help ensure your iPhone is able to edit videos efficiently.

Please let us know more about what's going on, to ensure we understand correctly. When you say that video editing is lagging, how do you mean? Does this happen when editing any specific videos, or when performing only certain edits? How long would you estimate it is delayed before completion?

So that we're on the same page, please also let us know which iPhone model and iOS version you're using. This can be found under Settings > General > About.

Let us know if the information in this guide helps:

How to edit videos on your iPhone, iPad, iPod touch, or Mac - Apple Support

Have a great day!

If by save, you mean export a video file, then yes it can take some time. Video creation is very processor intensive. Depending on the power of the processor in your phone, the resolution and quality of the video you are creating, it can easily take much longer than the video will play for to create the video. File sizes can also get huge. Getting stuck may be a result of running out of storage on your phone.
