By brolloh The slow-mo camera functionality is a superb creative addition on the iPhone 5S, we’re sure like us your first test was to film a running tap (if not, try it!). With the move towards video on social media platforms well underway with the likes of Vine’s 6 second Twitter friendly creations and Instagram’s 15 second alternative, slow-mo gives us a new avenue to explore. Getting slow-mo video into these apps is more hassle than it needs to be though!
Filming a slow-mo clip in the default camera app gives you the option to define when the slow motion portion will begin and end and save it in the camera roll.

Open Instagram or Vine and import this video however and you’ll find your slow-mo section is nowhere to be found.
Until developers or Apple (we’re not sure which) allow slow-mo creations to be imported or exported, we have to find an alternative route – there are two options.
What we need to do is force your iPhone 5S to package the video, as it stands presently your video is at the mercy of its own player (the one that defines slow-mo sections). The first option is one of the oldest tricks in the book – email the clip to yourself.

You’ll receive the video as a .MOV file which you can then save back to the camera roll, Instagram and Vine will both play nicely with this file.

The second option, and the one we prefer if you have a friend nearby, is to use Airdrop. The slow-mo video file will be created in the same way as emailing yourself, but far less compression is used when compressing the file for sending resulting in better image quality. Airdrop to your friend, get them to Airdrop it back and you’re away – a packaged slow-mo file will be waiting for you in the camera roll, Instagram ready!
Come back soon for more.
