This hidden feature of the iPhone allows you to make your own music videos

It wouldn't surprise us if you didn't know how to add music to a video on iPhone, as Apple has the feature well-hidden. So well hidden, in fact, you can't actually do it using the normal video mode in the camera app. This hidden feature of the iPhone allows you to make your own music videos.

Normally, any audio you're playing turns off automatically when you start recording a video on an iOS device. But there's a hack. If you use the QuickTake video option available on recent iPhone models, you can bypass this limitation and give your clips whatever soundtrack at the moment.

If you've been waiting to make an iPhone music video but without needing to download separate apps or having a second device playing a song in the background, now's your chance. In our opinion, it's small but super handy features like this that make the iPhone one of the best phones around. Just make sure your device is compatible below, and we'll take you through the process.

Compatibility: Before we get to the steps on how to do this, let's double-check you've got the right iPhone.

The QuickTake video feature that you need to make this work is only available on the iPhone XS, iPhone XR (both from 2018), and newer models, according to Apple's support page. It doesn't matter if you're using an older iPhone that still runs iOS 15, it has to be one of these models or a later one.

How to add music to a video on iPhone

Now you've got the right iPhone, and have your song and subject in mind, here's the process you need to follow.

1. Prepare your track of choice in whichever app you're going to play it from. Here I've got a song ready to go on Tidal, but this will also work with songs playing from Apple Music and Spotify.

2. Open the Camera app. Importantly: stay in the standard Photo mode (it should be what the app opens in by default).

3. When you're ready, cue the music! Do this quickly by pressing play in Control Center (swipe down from the top right corner of your phone, then tap the Play icon on the playback widget in the top right).

4. Tap and hold the shutter button. Holding down starts a video recording with your music still playing in the background.

5. From here, just release the shutter button when you're done recording. If you're going to be recording for a while and want to give your thumb rest, slide the shutter button/red recording icon to the right, where the padlock icon is. That will keep things rolling without you needing to press. To stop the recording from here, tap the stop button in the bottom center.

Once you're done recording, you'll be able to watch your video back from the Photos app like normal. Just don't go in expecting professional-sounding audio. Even if you're hooked up to the best Bluetooth speakers, the video is recording sound through your iPhone's microphone, which isn't designed for pro-level audio. While it's decent for everyday use, you'll need a better set-up if you're recording a promo for your next hit single — that's where our guides to the best mirrorless cameras and best cameras for vlogging come in.
