video right until the end so the four
steps for this guide and let's go and
jump straight into this here we are on
my computer and here is an example of a
video i went and compressed and the huge
difference it made in the file size as
you can see this one is originally 88
megabytes and this video here is
2.35 what a huge increase i believe
that's about 40 times smaller so now
let's go and get exactly into this guy
to achieve this i actually use a free
program so let's go and show you where
you can go and get it and then how to
fully use it and get this huge decrease
in file size so all you want to do is
going to open up your browser and come
to a search engine such as google then
all you want to do is go and search for
something called handbrake tool just
like so and you want to make sure you
come to the official website which is
handbrake.fr and do keep watching
showing the full download process then
all you want to do is either go and
click on download handbrake or click
other platforms if you want to go and
check it out for mac as well then all
you need to do is go and click on
download just like so and you can also
go and download older versions as well
i'm going to download the new version so
go and click download just like this and
as you can see it's around 20 megabytes
and it's now downloaded you then need to
go and open up your file explorer down
here to go to your downloads folder to
go and find it or it will be in the
bottom of your browser just like mine
now all you need to do is go and open up
this exe file and it's going to go and
start the installer and all you need to
do is go and follow the installation
instructions it's really simple and then
it's going to be installed on your
system and i'll see you then so
handbrake should now be installed on
your computer and you may have a desktop
shortcut i personally don't so if you
don't all you want to do is come to the
search icon down here look like a
magnifying glass go and click on it and
all you need to do is go and search for
handbrake just like so and it's going to
come up right that there so go and click
on it just like this and it's going to
go and launch it open so you either need
to go and open up a folder with videos
in or you can go and open up a single
video file personally i'm going to go
and take this option here
personally i'm going to go and open up a
single video file and it's going to go
and open up your file explorer the video
i want to go and convert is on my
desktop and here it is so i'm now going
to go and click on open just like so and
as you can see it goes and scans it and
here we are in handbrake so there are a
few key settings you want to go and
change so the first thing you want to do
is start at the top up here you can go
and change the preset personally this is
the default one i've always used 1080p
by 30 but you can go and click on it and
you can go and change it to any of these
as you can see there are loads to choose
from so i personally keep it fairly
simple but you could go and do like a
high quality one but fast honestly it's
gonna look absolutely fine
then you can come down here and choose
the format so keep it on mp4 that's a
really easy file to go and open then you
can go and have it web optimized if
you'd like um it's just gonna make it
more optimized for the web for
dimensions you don't need to change that
or filters you can come along to video
and then all you need to do is go and
make sure the encode is set to that one
that should be fine or you can use the
video on that's up to you leave the
video encoder but come down to frame
rate and what you want to do is go and
click on this and i recommend doing same
as source as your source may have a
higher frame rate than 30 then all you
want to do is change it to constant as
well so it remains constant the whole
time and there are the main settings and
all you want to do is come down to the
bottom to what save as so go and click
on browse and it's going to go and open
up your file explorer and i'm just going
to go and put this onto my desktop just
like so and name this com press again
just like so i've already compressed one
on my desktop there we go i'm now going
to go and click start encode and it's
going to go and start the encoding
process as you can see it goes and shows
the percentage down here so all you need
to do is go and wait for this to finish
and once it's finished it's going to go
and say cue finish just like so and then
you can go and close off of handbrake
just like this so here is the before and
after of the two clips i went and did so
as you can see the original clip was
three minutes 30 seconds long and 67
megabytes in size and the new clip will
go and hover over this one was 3 30 and
30 seconds in length and it's only 15
megabytes so overall i believe that's
still around a four and a half times
decrease which is still really
impressive and it's all going to vary a
little bit depending on the settings you
use and as well as the video clip you're
actually going compressing and just to
add in as well the quality looks
absolutely fantastic if you're going to
open up this video here as you can see
it looks really clear and then if we go
to the compressed version that also
looks really clear as well but of course
the best way to go measure the quality
for yourself is to go and try it out but
to my opinion i do use hammering the
whole time it barely affects the quality
at all but if you found this video
