Also, another reminder, the subtitles are
going to be down here it's going to say
english but it's actually a duo self for
english and mandarin chinese
additionally for all the camera gear
that we're going to be explicitly
talking about today
there will be affiliate links down below
for american and canadian amazon without
further ado
let's begin so in our last video we had
that side-by-side showdown comparison
between many different types of
stabilization systems so the first one
being with camera just like that walking
around
trying to dampen your steps that was
number one the second stabilization
system included this uu rig top handle
in conjunction with this small rig slr
cage the third stabilization system was
a steadicam over here the cheapest one i
could find at amazon the newer carbon
fiber steadicam the four stabilization
system
was using this motorized gimbal and in
my case it's going to be the g and crane
m2
and for the fifth and final
stabilization system that's going to be
our diy re trinity so that combines our
steadicam
as we mentioned before in conjunction
with our motorized gimbal in combining
them all we were able to make this
fantastical piece
if you haven't checked out that video i
do recommend you check it out it's going
to be up here i'm going to put a card
for you guys so you can click on that
and it's probably going to influence
your decisions the most if you consider
making this thing for yourself
instead we're going to be talking about
how it works when and why you would need
a stabilization system like this
and some other important considerations
and limitations now before we begin so
we can have like a baseline control i'm
gonna tell you guys what gear we're
running with today
at the bottom we have our newer carbon
fiber steadicam our motorized gimbal
today is gonna be the g and crane m2
at the top we're gonna have our sony a73
mirrorless full-frame camera i've
already balanced it so we can get this
boring stuff out of the way and now
let's turn on the gimbal
here we go so first we're gonna be
talking about how this stabilization
system
actually works
if you've had any experience studying
physics in the past you're probably more
knowledgeable than me in this regard
but if you haven't don't worry i'm going
to try to explain this as simple as
possible
for both my sake and for your sake so
let's first start with a side shot of
the diy re trinity
in the field of physics this is what
they call a class one lever a class one
lever is described by having its payload
and effort
on opposite sides to each other with the
fulcrum in the middle in the center we
have our pivot point the handle
in classical physics this is called the
fulcrum side a would be called the load
side b would be called the effort as we
act upon the effort arm with the input
force
the payload responds by moving in the
opposite direction so for example
if we were to push the effort arm up the
payload would move down
if you were to push the effort arm down
the payload would move up
remembering back from our physics 101
classes in high school and university
we know that force times distance is
equivalent to work subsequently our
class 1 lever system can be described by
this formula the force and distance of a
is equivalent to
the force and distance of b here our
forces are gravitational forces
this is the force of gravitational
acceleration or in layman's terms
gravity and because our formula shows
two sides of one hole we know that our
force and distances
are relatively constrained now in an
ideal system both the payload and effort
would be at the same distance
and same mass now in our case the diy re
trinity
although it is a class one lever it is
not an ideal system what i mean by this
is you'll notice that one of the arms is
longer than the other
in this case the effort arm is much
longer so for example
let's say we were to increase the force
of our payload let's add a step up ring
let's add a filter flip mount an nd
filter
let's add a microphone by increasing the
weight of our payload we've also
increased the force of our payload for
our lever to remain balanced we would
either have to add extra weights to our
steady cam
or we would have to increase the length
of the arm now that only considers the
class 1 lever in this axis
but because our steadicam has a three
axis gimbal we can also move in this
direction as well
but now that we talked about the
theoretical side we can move on and talk
about real-world application
in our observable universe we live in
three-dimensional space
we have our x-axis we have our y-axis
and we have our z-axis
usually the x-axis is denoted as the
major plane of movement
horizontal movement forward and
horizontal movement backward
y-axis on the other hand is horizontally
perpendicular
movement left and movement right z-axis
is vertically perpendicular to both
you have movement upward and movement
downward now usually when we think about
3d space
we only consider these planar axes x y
and z
but where cameras and stabilizations are
concerned we also have rotational axes
so these rotational axes
involve the angular rotational movement
around our planar axis so on our x-axis
we have a rotation rolling right
and rolling left therefore we call this
the roll axis on the y-axis we have
rotation tilting up
and tilting down therefore we call this
the tilt axis on our z-axis
we have rotation panning left and
panning right therefore we call this the
pan axis
so in total we have six axes to consider
we have three planal axes
x y and z and we have three rotational
axes roll
tilt and pan the planar axes are
controlled by us
the operator we can move up we can move
down we can walk forward
we can walk backward we can walk left we
can walk right
we can also combine these for even more
complex movements rotational axes are
then stabilized entirely by the
motorized gimbal
and in situations where we hold the
motorized gimbal using a different grip
for example switching from hammer grip
to dagger grip the pan axis motor now
stabilizes the roll and the roll axis
motor now stabilizes the pen
now this is why the diy r trinity is
important although we have a rotational
axes stabilized
we also forget that there's room for
human error usually while walking
our hips and knees move up and down our
plano axes
can lead to unforeseen vibrations and
this is sometimes noticeable in footage
even while we're using gimbals while the
framing and composition never changes
the perspective shifts from high to low
to high to low every time we make a step
and people usually combat this by crouch
walking and ninja walking and that's
where this guy comes in the three axis
steady cam handle dampens and smoothens
our control inputs and although the
class one lever rotates on a fulcrum the
actual distance of the payload from the
fulcrum gives us the effective
stabilization of the z-axis
and the y-axis comprehensively this
gives us five axis stabilization
y zed roll tilt and pan whereas
motorized gimbal by itself or even a
steadicam by itself would only be able
to give us three axis of stabilization
and that's why this thing is so awesome
one of the main reasons why i love using
this system is
i don't really have to ninja walk as
much as i used to i can reduce the
strain on my muscles my tendons my
ligaments and even my joints
it makes all of your dynamic camera so
so much easier
now after all is said and done this
thing isn't perfect
so now we're going to be moving to some
of the considerations and limitations
that i found while using the system now
of course i'm not the first one who came
up with this idea using a steadicam and
a gimbal
together we have already trinity and we
have some other youtubers
watching their videos i've seen them use
an overhand hammer grip and this upper
grip
is really really fatiguing right over
here on my forearm for myself though i
prefer using an underhand
hammer underhand like this and i haven't
really seen any noticeable differences
if it does and you know this
please do let me know but i want to
remind you guys the whole reason why i
use this diy re trinity system
is because i'm looking for comfort i
don't want to have to strain while i'm
making dynamic movements when i orbit
the subject when i
walk left to right when i move forward
so i'm going to be using that under
slung hammer grip
now the main considerations and
limitations i have for the system
is not really for the system itself i
mean if you really wanted to
you could spend 50 000 on the real thing
but most people don't have that kind of
money
so limitations i would say one of them
is your budget think about what you're
willing to spend
when investing in new gear i've seen
people use glidecams i've seen people
use fly cams but those things are so
expensive they're like 500
i just went on amazon this steady cam
here 79
i'm not saying it's perfect but it works
for me even the gimbal i'm using i'm
using the most cost effective motorized
gimbal on the market right now
and that's the g and crane m2 it's only
like what less than 300 us dollars
it works well with smartphones it works
well with point-and-shoots it works with
this
sony a7 iii although with some
restrictions of course
here are some of the downsides i found
when using the junkrain m2
the first one is that the rolex motor
isn't actually
entirely a true role access motor it
exists on an angle it's kind of in
between a roll axis and a pan axis
although it's super smooth and
responsive
it doesn't truly rotate around the
x-axis the second complaint is that the
pan axis arm actually doesn't extend
that far
so with my current setup my pan axis
actually isn't perfectly balanced
for a perfectly balanced motorized
gimbal while tilting it to the side
the pan axis is not supposed to swivel
at all in my case
if i'm using the a7 3 which is a bigger
payload and with the lens is kind of a
longer payload as well
the pan axis just swivels it has these
micro jitters on the roll axis back and
forth back and forth
my third complaint is that while
balancing for the tilt axis
the sony a7 iii is just too tall every
time you tilt
back the viewfinder just hits the roll
axis motor simply put there isn't enough
clearance
as a result i have to put the sony a73
lower on the tilt axis arm this gives a
clearance at the cost of not being
perfectly balanced now my suggestion in
avoiding all these problems is
get a bigger motorized gimbal get a june
weeble s
get a june crane or oh there's one
coming out right now the crane 2s
you can change the arm for the roll axis
so right now we have an angled roll axis
on this little guy over here
but on the crane 2s you can actually
switch this little arm
you go for an arm that's like this and
it's actually perfectly vertical but
yeah
get a g and we bless get a g and crane
get
a dji ronin get a motorized gimbal that
can support
and balance your payload again the
limitations exist within your budget
i'm the second coming of jesus christ
prove it turn that poop
into what turn that poop into whack for
me
i just avoid using the sony a7 3 for my
re trinity system
i've honestly found better results with
my sony zb1 point-and-shoot camera so
usually when i'm doing the diy trinity
i'll use the zv one
but if i'm just using the motorized
gimbal by itself i would use sony a73
when i use the zv1 for this whole
stabilization system
i get no problems at all it's absolutely
amazing and that's with
active stabilization off i'm just using
standard ibis
or just no ibis at all now if you don't
take my word for it and you still want
to use the sony a7 3 on the crane m2
here are the four lenses i would
recommend from my own experience i've
only been able to test two of them and
both of them are official sony lenses
so we have the sony aps-c series kit
lens this is the sclp 1650
it's only about 30 millimeters 1.2
inches in length so it's a pancake lens
it's got oss which is optical steady
shot that's your lens stabilization
it's got power zoom i think it's the
only sony lens that has power zoom i'm
not entirely sure and it basically means
that the zooming functionality has an
electronic motor assist
the other lens i would recommend and
have actually tested is this scl518f
this is another official sony lens full
frame this time it's at a 50mm
focal length with an f 1.8 aperture
although this lens is double the length
coming at 60 around 60 millimeters
they're honestly very very similar in
weight the fabrication uses composite
plastic materials
so it's actually really really light one
lens that i'm hopeful into trying
is the sel35f18f which is basically just
a wider version of this lens
though i'm not entirely sure if that one
is fabricated using composite plastics
so as for non-sony lenses there is one
that people do recommend
and that is the samick 24 millimeter f
2.8 full frame pancake lens with
autofocus it has a very similar size and
framing composition to this
aps-c lens over here but it comes with
the added bonus of being full frame
and having a wider aperture again i'm
gonna leave some affiliate links for you
guys down in the description down below
there will be some american affiliate
links and there'll also be some canadian
so yeah just check the description down
below
it's on a kit.co link and it's very very
organized it's at no
extra cost to you guys but it helps
motivate me and keep this channel alive
okay so i think it's time now that we
move on to the comments from last video
so she lululu music says this video
should go viral thank you very much
that's actually very kind of you to say
i'm just making content that i'm
passionate about she continues on by
saying what gear would you recommend for
filming snowboarding and diving
for sure but i'll give you guys a little
translation skiing snowboarding
and diving using what kind of equipment
is most suitable now i'm glad you asked
that question she lululu the short
answer is i would probably not recommend
a diy r
trinity system for action sports like
these
i would in fact recommend using a gopro
on a selfie stick or maybe even an insta
360 or 360 camera
the reason why is because this is a
little bit bigger it's a little bit
unwieldy and it could be dangerous when
you're using this for an action sport
that being said if you have another
operator who can help you out maybe they
are following you while you take the
lead it would be a bit safer
also uh i've had this experience in the
past i'm not entirely sure if it applies
to bigger gimbals like gion crane m2
and actual like you know slr gimbals and
stuff like that but in the case of my
first gimbal which was the aegean smooth
q for
mobile phones i actually noticed a
problem where when i was on a bus and i
noticed that while we were in motion my
camera kept
tilting up just like that every time we
were going uphill uh so i'm not sure if
inertia and momentum will play a role
into
gimbals like this so honestly i would
say probably just stick to a gopro for
now you're less likely to run into
problems concerning inertia as well as
problems that might jeopardize your
safety so yeah good question
if anyone else has any curiosities out
there concerning this
stabilization system please do let me
know leave a comment down below i also
have a discord so feel free to drop into
the server as well
anyways i digress so that's gonna be it
for today
i'm not sure if we're gonna continue
this series of the diy re trinity
these three episodes that we've already
released might be it
so the first video was just a general
introduction we did the small b-roll
cathedral town with a motorcycle
the second video was a stabilization
test where we compared different
stabilization together and we had a
showdown
side by side you could see all the
footage together we had five at a time
and we also did two at a time kind of
like that as for this last video it was
a comprehensive overview
on how it works when and why you would
need it and what kind of considerations
and limitations you might need to think
about
if you're planning on making this for
yourself so yeah that's gonna be it for
today guys don't forget to hit the
subscribe button down below
and smash that bell button while you're
at it we have a lot more content coming
up
not just with camera stuff we're gonna
be doing motorcycle stuff in the future
as well so yeah
definitely stay tuned i try to post
every weekend usually on sundays
so you sure as heck wouldn't want to
miss it see you guys in the next video
peace all right let's turn this bad boy
on
so first the camera i've already
balanced this balanced
where did the accent come from i've
already balanced this so you don't worry
you
