The Jello Effect in Mojo and options for stabilising your Smartphone or GoPro
July 31, 2014 2 Comments
If you are a regular follower of the blog you’ll know I talk about the iPhone as a mobile journalism solution a lot, but I also occasionally blog about one of my other interests: UAV (Unmanned Aerial Vehicles) or “Drones” as some call them, though thats a title I loathe.
Anyway the two topics have a common thread and that thread is becoming quite a substantial crossover. UAVs like the DJI Phantom have the option of a Go Pro Stabiliser Gimbal called the ZenMuse H3-3D. What this device does is it corrects the position of the GoPro relative to the pitch/yaw/tilt of the UAV. Or in simple terms it keeps the GoPro steady while the UAV is moving and tilting around.

The iPhone (particularly the older 4/4s) was extremely prone to rolling shutter and jitter-sometimes referred to as the “Jello Effect”. If you’ve tried walking behind a fast moving subject you may often notice the extreme shake in the picture and if you Pan (turn left or right) quickly all the vertical lines will bend very noticeably. During our Mojo courses I strongly recommend that trainees get into the habit of using either a tripod or monopod but thats not always practical. This is where the UAV Gimbal Stabiliser technology is now starting to have an impact on smartphones and GoPro.
A growing number of manufacturers are using the same Inertial Monitoring Unit Chip (IMUs) as those used in UAVS to create handheld brushless motor gimbals for Smartphones and GoPro. I’ve been trying to decide which one to buy for some time so I thought I’d share the ones I’ve been considering in case you are in the market for one also.

Its probably worth mentioning that these handheld units are baby versions of the much bigger and more expensive Stabilisers like the pioneering FreeFlyCinema Movi M5 | M10
