Apple's iPhone 5s has a new Slo-Mo video capture tool that can create a cool effect on moving objects by shooting at 120 fps (frames per second). Here, we show you how to use Slo-Mo in iPhone 5s, and how you can share the Slo-Mo video you've captured with others.
The first step is to open the Camera app on your iPhone 5s. Once it's open, you'll need to slide your finger from the middle of the screen toward the right edge until you reach Slo-Mo mode.
To begin recording simply direct the camera toward your subject and tap the red shutter button. You won't notice any difference yet - just capture the video as you normally would. We find shorter videos are often more effective.
If you'd like to capture a still while you're recording Slo-Mo video, you can do so by tapping the white button you'll see next to the red shutter button. This picture will then be saved to your Camera roll.
When you want to stop recording, tap the shutter button again. You'll now find your Slo-Mo video in your Photos app.
You can identify Slo-Mo videos in your Photos app by the small circle in the bottom left of their thumbnail.
How to edit Slo-Mo video in iPhone 5s
If you tap on a Slo-Mo video, you'll notice a timeline at the top of the screen. The blue bar beneath it allows you to decide when the Slo-Mo starts and finishes in your video. So if you've filmed someone running and then jumping off of something, you'll want to start the Slo-Mo from the moment he or she jumps, but keep the running part at its original speed.
To change the timing, move the black bars left or right. Where the blue bars are closer together, the video is at its normal speed. Spaced apart blue bars represent the Slo-Mo part.
How to share Slo-Mo video from iPhone 5s
When it comes to sharing your Slo-Mo video, there are some limitations. Tapping the Share icon at the bottom left of the screen will bring up the Share menu.
You can share with another iPad or iPhone user using AirDrop, but if you want to reach more than just one friend, you can share your Slo-Mo video to YouTube, Facebook or Vimeo, or you can send it via email.
However, it’s worth mentioning that Slo-Mo mode doesn’t record video in slow motion, it simply records many more frames per second than the standard video, which allows the iPhone's built-in software to apply a slow-motion effect after the event. This is fine while the video is stored on your iPhone or by a supported hosting service, but transfer it to another computer or website and it will be viewed as a standard video, albeit one created at a very high framerate.
YouTube, Facebook and Vimeo are all supported, and perhaps Apple and third-party developers will add extra support in the future. For now, though, apps such as Instagram will will allow to post only your 120fps source video.
There are a couple of workarounds for Instagram, however: one uses tools on your iPhone itself; the other requires you to have to hand a second iOS device.
Open the clip, make sure the slow-motion has been adjusted where you want it, then tap the Share sheet. Tap Mail, and your video will compress and attach itself to an email. Send this to yourself.
When you receive the email, tap the video to download it, then save it to your Camera Roll by tapping Share > Save Video. You can then upload the video to any third-party service.
The second way involves using another iOS device. Your iPhone will export slo-mo video to another iPhone, iPod touch or iPad via AirDrop, iMessage or Shared Streams. Once it’s on the other device, you can post the video to a third-party app.
It’s not ideal, but Mac desktop apps such as iMovie and Final Cut Pro X contain slow-motion modes that will allow you to slow down the 120fps video captured by your iPhone, and with similar quality.
