How to trim videos on your iPhone or iPad. Want to shorten a video clip to only the best part? Your iPhone or iPad comes with easy to use video tools built into the Photos app. You don't need any additional editing apps to trim your video clips down to the best parts. Open the Photos app and tap the video you want to trim. And in the top right hand corner, select Ebid. Now slide the handles to trim away the start and all the end of the clip. The sliders will set the new start and stop times. Preview the video to see if the trim is correct. Tap Done. And then save as a new clip. Saving it as a new clip gives you the ability to go back and do other edits to this clip later. If you're super confident that this will never need to be done again, you can choose Trim Original. This will of course also save storage space on your device. You can use third-party apps like iMovie or Splice to trim your clips. But this tool is a great way to clean up clips in albums and prepare them for later editing. In the video link now, you can learn how to use the Photos app to organize your clips into folders for albums on an iPhone to make the important to an editing app later much easier.
