According to the YouTube Description:
Captured on iPhone 7+ with the DJI OSMO Mobile gimbal during the course of 4 shooting days.
All i had to carry with me for the shoot was the phone, gimbal, small bag pack and an umbrella.
It was very easy to move around and to film and capture cinematic camera movements.
Used filmakr app with two main settings :
1. 4k, 30fps, 100mbps
2. 1080p. 60fps
Graded in After effects.
This is an amazing bit of work.
See the video after the break.
Imagine if that was possible with Stereo Video Recorder (prior post) for SBS 3D.
