If you’re mainly following a toddler with a camera, 60fps will capture more detail in the movement, but can look a little jarring and hyperreal to me.
Of course, whenever the numbers increase, you’ll be using more of your precious internal storage and battery, so take that into consideration before adjusting your settings.
If you want even more control, switch to Filmic Pro, available on iOS and Android, which features greater options in frame rate and the ability to lock focus and exposure, so your footage will never dip in and out of focus.
I’ve previously recommended Rode’s VideoMic Me as the simplest and best sounding external microphone for mobile, and the company now has a version for iPhones without a microphone jack, the VideoMic Me-L. Both feature a headphone jack behind the mic so you can monitor audio as you record.
The Sennheiser Memory Mic is a brilliant lavalier microphone that connects to a smartphone via bluetooth, but can record audio locally then sync back to the footage later; allowing the wearer to walk out of bluetooth range and still know the microphone is recording. The sound quality is fantastic, and is a clever solution for YouTubers or corporate training videos, although it is rather bulky. And because the Memory Mic only comes in white there’s no way of hiding it in shot, so it’s not a great option for movie makers.
If you want to edit video directly on your phone, the free iMovie app (iOS) is a great place to start, with Adobe’s new Rush software offering a little more control for Creative Cloud subscribers. The most fully featured mobile editor is Luma Fusion, available only on iOS. This multitrack editor supports advanced motion graphics, variable frame rates and access to royalty free audio, while taking advantage of the power of Apple’s iPad. I almost wish Apple would buy the company and rebrand the app as Final Cut Mobile.
If editing on a computer, DaVinci Resolve is incredibly powerful and, amazingly, free. DaVinci Resolve is available for Mac, Windows, and Linux.
