so I was actually doing an intro for a different video playing around with one
of these remember when these were in last year future spinner it gave me an
idea for a different video which I'm actually going to do now instead so
today I'm going to talk about video and shutter speeds and motion blur and that
stuff so let's do it
so when you're shooting video not so much video like talking head like this
or it doesn't really matter there's not a lot of movement but for things where
there's a fast-moving subject maybe someone running maybe your car driving
down the road choosing a different shutter speed well actually if that tail
that looks it will give it a different kind of blur it'll look more cinematic
more natural so it is important to pick the right shutter speed depending on
what you're filming the rule that applies to this the rule that people use
is called 180 degree rule basically the short version at the hundred ninety
degree rule is whatever frame rate you are shooting on you should double it and
make sure that the shutter speed is as close to double that frame rate as
possible so for example 24 frames a second equates to 48 closest child speed
- that would be a 50th or if you're shooting it 60 frames a second you will
get that be wrong then you want to go for one hundred and twentieth so shutter
speed of one one twentieth the purpose of this video is to show you how using a
different shutter speed will actually affect the motion blur and the
smoothness and I'm going to be using the pitcher spinner here really good example
to show you because it's fast and moving okay so for the purpose of this I have
the frame rate set to 24 frames a second aperture is set at one point four
because I like it buttery smooth in the background and the ISO is automatic so
my ISO should counteract for when I change the shutter speed hopefully not
impacting the image quality too much so the way I'm filming this I can't
actually see what the frame rate is but I'm going to be changing too because I'm
using Sony and it doesn't have a flip-out screen which is annoying so I'm
filming from the back with an iPhone to show you the screen afterwards and then
I'll overlay the shutter speed over the top I'm just going to talk about how the
motion blur here changes as we change the shutter speed also this is a pretty
good fidget spinner so it should stay consistently the same speed for at least
a minute which is probably as long as I'm gonna film changing the shutter
speeds for just so you can see 2 or 3 seconds on each different shutter speed
all right so I know we're starting at 150th this is where you typically want
to film it's gonna look most smooth most cinematic at this shutter speed
so you can see it's already starting to lose some of that blur the more I go off
the shutter speed blur is getting less and less it's starting to actually be
able to see the vision spinner now bear in mind if you look at the
iPhone that's still spinning at the same speed hasn't actually changed it's just
the frame rate it's obviously staying the same that the shutter speed is
changing so it's starting to look a lot less blurry
pretty much outline the entire fish it's better now
see how there's next to no motion blur now it literally just looks like the
fidgets spin is spinning slowly when in fact it's still fent spinning at full
speed
it looks like it's barely even moving see now actually looks like it's going
backwards now if I could go back to one fiftieth of a second there's the motion
blur you see the speed is still going out so there we go that was a real quick
short video on why is important to use correct shutter speeds when shooting out
24 frames a second or 60 frames a second if you want to get nice motion blur if
you liked this video today you hit that like down below subscribe to my channel
if you're not already a part of it I actually think you need to hit that
little bell now if you want to actually get the videos sent directly to you
subscribe apparently no longer works wait used to so yeah if you want to see
him straight away hit that Bell thanks for watching and I'll see you in another
video see ya
