You definitely able to to plug the rode smartlav (or just regular ear phones) in to one phone, and other phone use a camera. Watch the videos on www.microphone.rocks all shoot using this app with regular iphone earphones.
Cool Start! I like it. Check out www.microphone.rocks YOU may find it interesting for you future work ;)
Thanks for having great tips at one place ;)
One year ago I realized, that there are a lot of not professional people who want to shoot video at a distance, for example, while having sound recorded separately.
AND there is a BIG PROBLEM for majority! HOW TO SYNC?
I and my team came up with a solution, it called MICROPHONE ROCKS (www.microphone.rocks)
It Allows to shoot video using two smart devices, one as a camera and another as a microphone.
Everything sync AUTOMATICALLY at your smartphone. AND you never need to spend time on computer doing synchronization. Check it out: www.microphone.rocks
