Advanced Usage

As you get more and more familiar with the 4th Axis Stabilizer you’ll uncover your
own little tips and tricks to make your stabilizer do more. Here’s a few things that
I use on occasion;

Semi-Rigid Mode

Ok, I know some of you are having a chuckle at the name but I’m serious!
This is a bit of a dark art to get right so don’t worry if you can’t get it easily.
You can’t use Rigid Mode as part of a shot that goes from soft suspension
to Rigid Mode as the locking motion will give an obvious jolt in the
footage. You

might find that there are times when you want this transition

so what you can do is rather than fully locking the arms just apply enough
inward pressure on the handles to lift or lower the gimbal so that the
majority of the suspension is mostly locked and you can do your controlled
rapid movement. This takes a bit of practice but if you do these transitions
like whip pans regularly then it’s well worth the practice to get it right.
