Video files are a bit like suitcases. The bigger they are, the more difficult they are to carry

around and to store. But what if I told you that there was a way that you can pack all of your

video content into a smaller, more manageable file size? Well, in this breakdown video, I'm going

to be showing you how you can compress your video files into smaller file sizes without losing

any of your original image quality. In order to encourage your videos into smaller,

manageable file sizes, you'll need to run them through a software called Handbrake first.

Originally created for ripping DVDs, Handbrake is a free open source software that you can

use to transcode, convert to other formats and even resize your own video files. The app itself

is compatible with Windows, Max and Linux operating systems and it supports a variety of different

video code acts which I will show you later on in the video. But enough of my Rumble, let's jump

straight into the breakdown. So obviously the very first thing that we need to do is to go ahead and

download and install Handbrake and I'll leave a link in the description of the direct link that

you can go ahead and download it. So after it's been installed, you'll see that the app will appear

with a pineapple and cocktail glass as it's icon. I have literally no idea why the developers chose

that icon, but it's kind of a vibe I have to admit, it looks cute on the desktop. Anyway, once you

open the program, you'll see that you get the option to either upload one singular file or an

entire folder. For the purpose of this video, I'm going to be focusing on just one single video clip,

but just before I import it, note that the video that I'm about to import is around one gigabyte

in file size because we'll come back to this a little bit later. After importing, you'll be able

to see all of your clip property details such as the resolution, the frame rate, the audio tracks

and so on and so forth. Now to break down the initial interface, the very first important button

is this preset tab here. This is where you have the option to select a preset based on your

output format and I'm going to go all the way to the bottom here and select production standard

as this is typically the best for professional video editing workflows and this is suggested by

handbrake themselves, so that's normally what I go for. For format, I'm going to leave this to MP4

and I'm going to make sure that web optimised and alinev are ticked as these are the best for

social media videos and that's typically what I tend to create. In the dimensions tab, you can crop

or change the resolution of your video but I'm going to skip past this for now, likewise for the

filters as well. For the purpose of this context, you probably won't need it but it's there if you do.

Now for the important part, the video tab. Firstly, in this video encoder drop down, you can see that

you have lots of different video codecs that you can choose from. I'm just going to keep this

to H264 as this is the most compatible video codec nowadays but these other options are something

to be aware of. For frame rate, if it isn't already selected, then make sure it is set to

same the source and that the constant frame rate is also ticked. Then on the right hand side here,

you'll see that you have this quality slider, so if we drag it all the way to the left, you'll see

that the number increases and if we drag it all the way to the right, the number decreases.

Now this is essentially a quality slider, so the further to the right you go, the bigger your

file size will be and the better quality you will have in your image. But the further to the left

you go, the smaller your file size will be, so there will be a loss in quality. Now I've played

around with these settings a little bit and I've found that 22 seems to be the good sweet spot for

me but I'd probably recommend sticking between 18 to 25. Next we have the encoder preset. Now this

feature basically tells your computer how much processing power it will need to encode the entire

video. However, I would just keep this set to fast because if you put it any slower, then it's

going to take absolutely ages, literally snails pace and we haven't really got the time for that,

so I'd recommend keeping it to fast. For the rest of the settings, I'd keep them the exact same,

but if you have any audio in your video, then I'd recommend checking this audio tab to make sure

that it's set to 320 bits because sometimes it automatically sets it to lower and you just want

to make sure that that's 320. Lastly to save us from inputting all of these settings ever again,

we can save this as a preset up here so you have it for future reference. And just before we start

encoding you want to make sure that you have your file saved in a location where you can find it,

and then after that all is left to do is to start the encoding process and let ham break do its

thing. And that's essentially it. So if we compare the file size as you can see we started with

a 1GB file size and now it's been dramatically reduced and if we play them back side by side,

you'll notice that there has been no quality lost whatsoever. They both essentially look brand new.

But that's it for today's video. As always, if you have any specific problems or questions

about ham break, then let me know in the comments section below. But if you enjoyed the video and

you want to learn more about video production, video editing and all things about content creation,

I'll catch you in the next one.
