Hello everyone, welcome back to Pixel Viilage and I'm Radhakrishnan

Let's talk about cinematography for a change.

Cinematographers use camera movements effectively to convey an emotion,

heighten the feeling of a situation. Until 1975 the most popular camera

moments that were available to be used were a dolly or a camera crane. But in

1975 Garrett Brown, a camera operator, invented a device using which you could

mount a camera onto a handheld device, run with it,

slide with it, climb steps, climbed down the steps, without creating camera jerk

And that device was branded as Steadicam which subsequently became a generic name

for all camera stabilizers. Lots of variations of that Steadicam in various

price points and shapes and sizes became subsequently available and we've been

using it very frequently. The most recent entrant of this whole game is something

called a 3 axis Gimbal. In this video we're going to talk about such a Gimbal

and in typical Pixel Viilage fashion we're going to present to you a set of

products which offer great value at a fantastic price range.

It's the Moza range of camera stabilizers from a company called

Gudsen Gudsen Gudsen doesn't matter

So they offer three types of products the first one is for a DSLR and the

second one is for a mirrorless camera and the third one is for a mobile phone.

So let's unbox them. Nice, all of them come in hard boxes. What we do is let's

open one by one and see how they look. So this one is for the DSLR. Let's get these

guys out. This is the DSLR Gimbal, meant for full-size DSLR

it can carry up to 3.2 kilograms of payload

Now let's open the one for the mirrorless. Nice case, very compact let's

get this guy also out. This one is for the mirrorless, much lighter in terms of

construction but similar design. It of course doesn't have the hand grip and

the remote control. Let's look at the one made for the mobile phones now, ok. Very

carbon fiberish looking carry case. Very interesting. Let's get this guy out. Well

much lighter of course it is for a mobile phone so hence it is very light

and I'm assuming that it's much more easier to operate too. What we going to do

next is going to see what a Gimbal is, how you going to mount a camera onto it

and how to use it. For which I don't require the mobile phone one and the

mirrorless camera gimbal. And let's come to the DSLR

So before we actually start setting up the Gimbal and start demonstrating it

let's try and understand the underlying concept behind the design of a Gimbal

which will definitely help you to set it up and use it. So it involves a little

bit of physics this is a box, right of course you know it. It occupies three

dimensions, width, height and length in space. It is staying now stable like this

because Earth's gravitational force is pulling it down in a straight line. Now

there is an imaginary point somewhere within inside the this box called the

center of gravity, from that point which in all directions the weight is

distributed equally. The moment that center of gravity goes outside the

support line for example, here it is being supported by the base, imagine the

center of gravity is somewhere here and if I start shifting this way as long as

that centre of gravity stays within the support of the body the

object will come back it's its original place, the moment it goes

outside the support line the object becomes unstable and it will fall over

Now I am trying to hold this using my fingers. To be able to hold it, I need to

do something called balancing. I'm trying to find a point of support which is

almost perpendicular to the center of gravity where the weight is distributed

equally onto all sides because I am now supporting only from

bottom. If I can't find that, it will fall over but see what happens when I start

adjusting my hand. So, the moment it starts moving away from me

or moving closer to me, I start adjusting my hand, what is happening now is that by

readjusting constantly I am keeping the center of gravity and my support line in

a straight line. Thereby this box is now stabilized well what is happening here

is that I'm using my wrist, my elbow and my shoulder joint to balance, to

constantly readjusting these combinations to keep this guy in balance

Now it's almost an involuntary action but somebody is giving that instruction

who's that? It's my brain cut to my Gimbal. Can you pass camera please? Thank

you. Imagine the camera is on a tripod on a very stable surface, you will continue

to get very stable image but when you start running, moving, walking with the

camera while filming, you're constantly moving the camera and by creating a very

jerky moment but in order to create a very silky smooth soft movement you will

have to constantly keep the camera in a very well balanced position. In order to

achieve the smooth fluid movement, the Gimbal does exactly that, it takes the

help of three motors and a gyroscope. The gyroscope acts like our brain and these

three mortals act like the joints in our hand. Hope it was clear, and you could

understand the concept behind the Gimbal design. Now let's get into setting up the

camera on the Gimbal. A Gimbal can be controlled using three different ways,

one us using the on/off switch and the joystick which is behind the Gimbal,

second is using a remote control which is here and you can also control it

through a mobile phone. All you need to do is to download the mobile app from

Gudsens's website. The mobile app is called Moza assist. Once you download it,

like any other mobile app, you have to pair it with the device and then you can

start controlling it from the app itself. Before you set up a camera on the Gimbal

you have to tune the Gimbal and calibrate it it is like aligning and

balancing your car wheels or calibrating your computer monitor. Once it is done

then you are ready to do your work. Now on to the most important ritual of

setting up the Gimbal, which is balancing the camera on the Gimbal. Remember,

balancing the camera should be done only on the switch off position

never attempt that in this power switched-on position. If you do that

it's going to be a little expensive for you. Again, there are few things to

remember before you start setting up. Make sure the camera is fully prepared

so that you don't have to add or remove anything from the camera. Once it is

balanced and is on the Gimbal, things like memory cards, battery, the rear

monitor positions, or lens hood, or a filter all that needs to be decided

before you start balancing the camera on the Gimbal. There are a list of cameras

which are supported by Moza air. The list is available on the website, is also

available in the instruction manual. In case if you are using any of those

cameras which are supported well then you can use the cables like there is one

for Nikon, there's one for Sony and one for Canon. You can use these cables and

once it is connected, balanced you can control the camera from the remote

control and the app. It is usually used for triggering the camera also setting

up your time-lapse shots motion control shots ok. So another

important thing, make sure that this arrow is pointing upwards. By any chance

if you pick it up like this, the arrow will point downwards and the Gimbal will

never balance, so make sure that this is pointing upwards all the time and when

you pick up the Gimbal from the box all these adjustments arms will be, you know,

in a kind of a minimum position. Make sure that you release them and keep them

extended comfortably outwards also ok. So, that basically creates enough space here

to accommodate a DSLR. Pick up the camera, the Moza air comes with a quick-release

plate and an adapter, so that now you don't have to struggle with the Gimbal

while connecting the camera. So this is the base plate, ok, I am going to mount this

on. Ok ok. Two things, first is the arrow should

point towards the lens and second is make sure that the base plate is

absolutely straight. Okay, now just tight pick up the plate,

slide it in, okay, make sure that it is tight completely because if you let it

go, it'll kind of fall off the Gimbal. It can be pretty costly, so make sure that

it is fixed properly into the base okay. Now for a cinematographer, this is the

tilt and for the Gimbal, this is the pitch. Cinematographer calls this PAN but

the Gimbal guys call it YAW and this is called the ROLL, so pitch, yaw and roll

these are the three controls that we will learn about and we must remember

this terminology because you know as cinematographers and as the photographers

we are not really familiar with this terminology. Okay I suggest that you turn

it this way and make sure that the weight distribution on either side is

proper. You can balance this by shifting the pitch arm, so I'm going to slightly

adjust okay okay. This is heavier this side okay. Now this is balanced perfectly

like this okay. The next angle which is the front and back balance currently it

is a little rear heavy, so, what I have to do is to loosen the base plate and shift

the camera a little forward okay okay. It is tilting a little forward so I need

to shift it a little towards the back and that's now front heavy. I have a

small suggestion to make to Moza people, like in those technical cameras, maybe

they can consider, you know, incorporating gear knobs, so that movements can be

pretty calibrated. I don't need to guess the, you know, shift, you can actually make

a turn and the arm moves in very controlled fashion

I think that'll make the balancing really easy. Moza can probably consider

using that. Okay. Now this is now perfectly balanced for the pitch angle

Now what I need to correct is the roll angle what you have to do is to adjust

the role adjustment arm, push it to the appropriate side so that the camera

start balancing on its own. Now it's still heavy on this side which is your

right side okay. Now it's become straight so what I have to do is to tighten the

arm. Right, it's better. The next axis that I need to adjust is the yaw axis for

which I have to remove the hand grip. Okay, so let me remove the hand grip so

what do you have to do is to I'll let me hold it like this

The idea is to get the yaw arm to come and stay here. Release the yow

adjustment arm knob and slowly start pushing it this way okay

Not yet get a little more and yes okay. As you can see, even the yow axis now is

balanced, let me connect the hand grip again. Right now the camera is perfectly

balanced on the Gimbal and the Gimbal is ready to be used. To start using, first

remember to switch on the camera and activate the live view

I have not switched on the Gimbal now and as you can see the horizon is not

corrected. The virtual horizon indicates a small error in balancing. Now see what

happens when I switch on okay the camera quickly stabilizes itself the gyro

inside send signals to the corresponding motors and corrects the horizon perfectly

Well I'm going to lift it up as you see there's no function dialed in the Gimbal

To dial it in a function you have to use a particular combination of pressing the

joystick and the power button to address function. You press the joystick once, the

Gimbal will switch to something called Yaw-follow mode. Yaw like I said is

equivalent to a pan. So when you turn, the camera also will follow the Gimbal

also will follow the movement of your hand. I'm going to press the joystick

once, okay so this is in your follow-mode. So

I'm going to turn, if I turn the camera also will follow. I turned the other way

the camera also will follow but at this time if I try to tilt it down

the camera will not tilt down or will not tilt up, so it is only in the yaw-

follow mode. But in case if you want to tilt up or tilt down then you need to

activate the next mode which is the yaw and pitch mode. For which I need to press the

joystick twice in quick succession one two. So the Gimbal is now ready to do the

yaw and pitch-follow mode. Okay it is now yaw-follow and the can you see the

camera tilting down, when I tilt up the camera also tilting up, tilting down,

tilting up and yaw and yaw

Now the camera is now in a, you know, wherever that you left the camera isn't

that's the place the camera is now aimed at, you need to bring the camera back to

the zero zero position before you dial in a new one

For you to get a reference that is so to do that you need to triple press the

on/off button. So when you triple press the on-off button, 1, 2, 3, the

Gimbal will reset to its zero zero position and it is ready to take the

next instruction. What I'm trying to do is now to activate the roll moment for

roll follow mode the sequence is four times the joystick. 1, 2, 3, 4

Now the Gimbal is ready for the roll follow function. Now I'm going to roll so

when I roll, can, if you can see the camera the camera is rolling along with

my action

and there will be times when you don't want any of these functions to take

place. You just want to follow the person with all these modes locked in, meaning, no

yaw, no tilt or no roll, for which I need to press the sequence is 3 times the

joystick 1 2 3. Now the Gimbal is in all locked position

so what happens is whatever I do the camera will not move from its position

at all. If I turn, pan, tilt, roll, it will stay

exactly where it is giving you a very interesting feel. So when you use the

Gimbal and force the camera to follow you, it is called a follow action, but if

you're using the joysticks to create that motion it will be called the

control action. So I am panning left and panning right exactly how you would use

a joystick. I can tilt up and tilt down. Now to activate the roll control mode,

you need to press the on/off button four times quick succession 1 2 3 4 ok now

when I use the joystick the camera start rolling

there is another exciting mode called the inception mode in Moza Gimbals. To

activate that you have to press and hold the joystick and press the on/off button

3 times

What else is left? You can also use the joystick and the on/off button to

calibrate, to put the Gimbal to sleep when you are not using for some time and

a few more functions but mainly there are two big operations that you do with

it. One is a follow, one another as a control

and also like I mentioned earlier if your camera is compatible with the

Gimbal, you can use the on/off button to even activate the recording. One press to

start recording and press again to stop recording. Well and of course there

is also an option to take a still photograph. Press the on/off button twice

and the camera will take a still photograph that is provided the camera

is compatible with the Gimbal. Like I mentioned earlier, all the functions that

you do with the joystick and the on/off button can also be done with the Moza

remote control, it's a Bluetooth device so you to you have to first enable and

pair this remote trigger with the device. So the controls are very limited, so you

need to go through a routine which we need to remember properly. The only

advantage is that you have a small readout here, so press the on-off button and you

will see a small dial. Long press the option and the first option is pair. What

you have to do is to switch off the Gimbal, activate pairing, switch on the

device and it'll say paired ok which means now the device is paired with the

remote control. What you can do is you can control the speed of the yaw, speed

of the pitch and also control the roll. If your camera is compatible to

like I said earlier, you can trigger the record function from the remote control

Okay so let me increase the speed to high for both yaw and the pitch okay

Now the turn is much faster, the pitch is much faster, once I reset,

change to completely low, now the pan or the yaw is very low. Tilt is also very

low. In case if you need to vary the speeds of pitch-follow and yaw follow

it can be adjusted only from the mobile app. There is another very interesting

function which the remote control offers is called the mimic follow function. I

have to take the hand grip out, hold the hand grip in my hand and long press the

option button, you will get a series of options, scroll down and there is a

control called motion control, and you say start once. It is start, whatever I do

with the hand grip will be mimicked or followed by the Gimbal there, which is

very interesting. If I am remotely viewing the footage or someone else's

operating the Gimbal and you want to control the camera, this is how you do it.

You can do all the functions. I think the role function may not work

while I am doing this. The role may not work only pitch

and your pitch and yaw

For me it was not just a review, for me it was a learning, I was playing with all

these Gimbals for almost one week and I realize more I learn there's more to be

discovered. I I really envy those people who can

really handle this and create magic out of this. Our smooth steady interesting

shot can really add value to your film, so much so that some of the great

cinematographers of the West have their favorite study can operator. The story

goes that the three times Oscar award-winning cinematographer Emmanuel

Lubezki waited almost a year for his favorite Steadicam operated to get free

while doing the movie Tree of Life for Terrence Malick. Which means if you

practice enough and raise your level to that even someone like Lubezki will

wait for you. Bye for now
