STOP GIVING PEOPLE A HEADACHE!

​The following is a post by Sérgio Miranda and expresses his point of view on action video production. He is neither a professional cameraman or a video producer. His experience comes from consistently shooting and editing action videos during the last 3 years for promotional brand-activation events and for his individual or group of active clients, runners taking part in his running tours in the lovely city of Porto, Portugal.

seriously now: you need to stabilize your camera!

We've all witnessed big fails in what comes to action video's quality, those where the cameraman (or woman) is running, with such shaky footage that it makes it nearly impossible to watch beyond the 3 first seconds without getting seasick... in this post I will demonstrate how these nausea-inducing videos can be easily avoided with a small $ investment and a few editing tricks!

​It's actually very easy and, once you get the hang of it, you'll come to love it and possibly develop a healthy addiction to video production!

​So,  bear with me:

What DOES POV stand for? what is it?

First of all, what is Point of View (POV) ?

That's just a technical way of saying that the video shooting technique enables you to experience a scene first hand, by putting you in someone else’s shoes. In this case, the running shoes of a running tour guide! It is a shooting technique that shows you my perspective 'of the scene', literally from my position in the front, leading a running group throughout the city. I won't be talking about drone video techniques here (expensive gear/legal issues involved/not POV...)

HOW TO EFFECTIVELY STABILIZE AN ACTION CAMERA

In the past I have tried it all: holding my hands really steady, footage-stabilizing post-production softwares, filming with an handheld stick, diy mechanical stabilizers...  many wobbly videos and 'deshaking' softwares later, I realized I had to stop wasting my time and purchased my first gimbal (that was already 3 years ago!)

It was like stepping out from the darkest of alleys to the most luminous, light-filled square of Porto - I experienced this massive change in quality: the handheld 3-axis gyroscope gimbal completely changed my ability to shoot action videos and gave my viewers' stomach a lot more comfort!!! 

My first option, back in 2016, was a Feiyutech G3, specifically designed for GoPro cameras. Presently, with my non-waterfproof 4-year-old Gopro Hero4, I use a Feiyutech G5 which claims to be splashproof (I will get to this topic, further below).  

There's obviously other brands and options for action cameras, also for those in need of a smartphone stabilizer, particularly who regularly needs to create content for Instagram stories, IGTV or Facebook live broadcasting ( I am not competing in that championship yet, myself...)

Recently I too have been looking at the GoPro7 & 8 with built-in stabilization, and seeing some online videos that are not as shaky as the ones from previous GoPro models. Still, they're far from perfect and, for the most part, they are not horizontally leveled....

IS there a way to stabilize a camera without electronics?

There is.

Actually there's a few.

While there are inexpensive and even diy methods, most of them consist of a bulky frame with heavy counterweights - not the best option when running... Other methods, like a traditional tripod or 'the string hack' just below - the cheapest stabilizing method I know of - are only possible to use if you are standing in one place...

(these stills from a youtube video show someone using 'the string stabilizer' with a DSLR camera
​but the same strategy can be used with a GoPro)

​Now, if you're running and shooting video at the same time, you'll need extra help for stabilizing your footage. The electronic kind.

HANDHELD 3-AXIS GIMBAL - what are the benefits?

Let me list a few for you:
​

• the gyroscope gimbal stabilizes the image - removes the shaking and other high-frequency up and down or sideways movements.
• it levels the camera horizontally!
• it allows you to have these perfect 90º to 360ºrotations in the horizontal and vertical axis!
• the stick (where the batteries are) is great as a handle - your hands(and sweat) are kept away from the GoPro lens. 
• battery in the gyroscope will easily last for 4 hours - that's a couple of 2hour standard running tours in Porto!

Two bonus features I use all the time are:
​

• a thumb-operated joystick - you can smoothly rotate the GoPro vertically and horizontally

• additional operation modes - a small button allows you to shift from free vertical rotation to blocked - this way the GoPro will follow when you tilt the gimbal up or down.

editing software - where the magic happens

Though the gimbal will do most of the stabilizing work for you, it won't provide a 100%stable 1hr video...mainly because you're running - and, in my case as a running guide, also talking, making gestures...

That's where the video editing software comes in:
​
Since day one I have been using Imovie, a free video editing software that came with my 10 year old Macbook. There's of course many other options on the market, Adobe Premiere Pro, Final Cut Pro... some web-based with a free-trial period. Most of them require some time to learn how to perform even the most simple of operations, but don't see it as an impossible obstacle. It'll be a learning process and will save you time in the future.

I find the iMovie to be have a good balance between the number of features and ease of use. Because it has so many features - image filters, transition effects, image crop, green screen feature, semi-professional precision editing and a bunch of other options - there's still so many things in there that I haven't yet explored to its full extent. 

Investing my time in learning on how the video editing software works has provided me a world of possibilities and lot's of freedom to be creative. 

I will address the video-editing stage of production in a future blog post. ​For now I will only reveal a few tricks concerning stabilization:

• slowing down the speed of some of the clips by only 10 to 20% will provide much smoother videos.
• Keep the clips short. My rule is 3 seconds per clip, roughly. I never go above 7 unless I have a clip where I am not moving. The clip lengths affect the mood of the video, they set the rythm. If I am creating an action video, I want it to be...active!  It's also much easier for me to pair the footage with rock/pop/hip-hop music if I keep clips to the 3seconds maximum. It's like learning to dance the waltz: 1 - 2 - 3 >next > 1- 2 - 3 >. . .
• I have tried the clip stabilization tool in iMovie but it just regurgitates distorted, wobbly imagery that looks really unprofessional.

Here's 3 different examples of what I did with a 120Euro/130 dollar gyroscope gimbal and a GoPro ( all in a beautiful setting, Porto... that also helped ;) )

As you can see, most high frequency motion was filtered and there's no blurry or wobbly scenes.

​Surely there's some up and down low-frequency movement of the camera but that's something I find acceptable on any running video - it's a POV video after all, isn't it?

​NOTHING LASTS FOREVER

Now that I've pointed out all the good stuff, let's talk about limitations.

Despite being advertised as a waterproof product, some of the screws in my gyroscope gimbal now present some corrosion. After a few months of use, the handheld device shows signs of deterioration - sweat and humidity are relentless on low quality metal parts like the small screw in this picture.

This is the 3rd gimbal I own but the first one claiming to be 'splashproof'. While the two last ones were lost to problems in the eletric rotors - probably corrosion - this one, however, seems to be holding up fine (for now!), despite the corroded screws...

There's also some transient issues regarding the leveling of the camera when I turn on the gimbal. Usually it takes about 2 seconds to reach the horizontal but, from time to time, it will take extra 10 to 30 seconds...

​Everything/one becomes slower with age, am I right? ;)

On the bright side: my GoPro Hero4 has fortunately outlived two of the 2 gyroscope gimbals...! That's one impressive piece of electronic 'gizmo'!
