I have recorded some screen video on iPhone using the built-in screen recording tool in iOS. It is muted without background sound and I need to add a song from my music library to the recorded video on iPhone. Is there any simple app can do this job?
Adding music to a video on an iPhone can enhance your video content in various ways and serve a range of purposes, depending on your creative goals and the type of video you’re creating. iMovie provides a user-friendly way to edit videos and add music directly on your iPhone. It’s a versatile app with many features for creating and editing videos. VideoShop is a third-party app which allows users to edit and enhance their videos with various features and tools. It’s known for its user-friendly interface and a wide range of editing options, including adding music, text, filters, and special effects to videos.
In this quick guide, we will show you how to add music, songs, voice over, audios, sound recordings to videos on iPhone iPad using both iMovie and VideoShop.
Method 1. Add background music using iMovie
To add music to a video on an iPhone, you can use the iMovie app, which is available for free on the App Store. If you don’t have iMovie installed on your iPhone, you can download it from the App Store.
Launch the iMovie app on your iPhone. The Projects screen opens automatically. Select Movie as the project type from the Start New Project section.

You will then be taken to your device’s media library. Select the video you want to edit and tap the Create Movie button at the bottom to import it to iMovie.

Tap the Add (+) button to add music to your video. You can add Voiceover, or select Audio, then choose from the following options: Soundtracks, My Music and Sound Effects.

After adding the music to your project, you can trim it, adjust its volume, and customize its start and end points to match your video. To trim the music, tap on it in the timeline, then drag the handles at the beginning and end of the music clip to the desired positions. You can also use the Split tool to cut the music and video clips, arrange them as needed and then delete those unnecessary audio and/or video clips.

Tap the Play button to preview your video with the added music. Once you are satisfied with the video and music combination, tap the Done button at the top left corner to return to the Projects screen. Tap the Share button at the bottom, then choose Save Video to save the edited video to your Photos app.

You can then share the video through various social media platforms or messaging apps.

Voice over videos on iPhone
In the video editor, select Voice to start recording any sound or voice and directly import it to your video. For existing voice recordings, you will need to convert the iPhone voice memos to MP3 before you can use them as the background sound of your iPhone video.
Importing music from computer to iPhone
If you have saved music on computer, such as MP3, M4A files, you can sync them to iPhone using iTunes or other third party iOS file transfer apps, then choose IPOD in the Videoshop app to add the MP3 to your video.

I’m trying to insert a song from my iPhone iTunes library but keep getting “apple music or DRM-protected songs are not compatible. Please use songs from iTunes music (or other downloaded mp3s) and try again”
Is there a way around this?
Thanks for any help
if the music is DRM-protected (Digital Rights Management) or not downloaded onto your storage, it may not work. you need to save a copy of the music on your local storage before you can import it to the editor apps.
as far as i know, no easy way to get around this. Apple Music tracks are DRM protected. This means that you cannot freely transfer songs sourced from Apple Music to a PC, even if the songs are downloaded for offline use on your iPhone. a workaround is to record the music. for example, you can record the music from iPhone using your computer, then import the recorded file from computer to iphone. however the audio quality may suffer during the recording process.
Hi, how can I add music to my video if I want to just add a sound clip from the middle of the song? Thanks
when you try to add a music song to your video using above Video editor app, you will have the options to trim the song or sound, select the start and stop time, add fade-in and fade-out effects, etc. you can also drag the audio clip below the video frame view to choose where to start the audio instead of starting the audio playback from the first beginning.
