How To Edit Subtitles In Movies On Linux With Aegisub

Many video players support loading subtitle files alongside video files, even on Linux. However, it’s much better to add subtitles directly to the video file. Going this route ensures that no matter what program plays your video file, the subtitles will always be present. When it comes to importing subtitles into video files on Linux, there’s no better choice than Aegisub. It can work with a multitude of different video file codecs and subtitle formats. Better yet, it comes with a graphical editor that allows users to edit subtitles in movies in real time.

Note: downloading subtitle files online is illegal. Please obtain subtitles by extracting them from personal movie backups made legally, and do not share them with anyone!

Install Aegisub

Looking to install the Aegisub app on your Linux PC? You’re in luck; many Linux distributions have packages of it directly in their software sources, so the process is quite easy. To install it, open up a terminal window and follow the instructions below for your respective operating system.


Ubuntu Linux usually has Aegisub readily available in the software sources. However, for the latest version of the OS (Ubuntu 18.04,) there’s a bug that prevents it from installing. Luckily, if you’re on 18.04, there’s a third-party PPA available. To install it, open up a terminal and use the add-apt-repository command.

sudo add-apt-repository ppa:alex-p/aegisub

Next, run the update and upgrade commands to refresh and install any updates available on Ubuntu.

sudo apt update

sudo apt upgrade -y

Install Aegisub with:

sudo apt install aegisub


sudo apt-get install aegisub

Arch Linux

sudo pacman -S aegisub


It’s possible to use Aegisub on Fedora Linux, though users will not be able to install it through the traditional software sources. Instead, RPM Fusion needs setting up.

Note: replace X with the release number of Fedora Linux you’re using.

sudo dnf install -y

sudo dnf install aegisub -y


OpenSUSE users looking to get Aegisub will need to first enable a third-party software source.

Leap 15.0

sudo zypper addrepo opensuse-multimedia-apps

Leap 42.3

sudo zypper addrepo packman


sudo zypper addrepo opensuse-multimedia-apps

Install Aegisub with the Zypper package tool:

sudo zypper install aegisub

Generic Linux

Add Subtitles To movies

Adding subtitles to video files with Aegisub is surprisingly simple. It starts out by importing the movie file. Import your movie file to the app by clicking the “Video” menu button, then selecting the “open video” option.

Browse for your video file in the “open file” window to load it up in Aegisub.

After importing the movie file into Aegisub, the app will scan the video file quickly, so that it can play it back in real-time, during the subtitle editing process. When the scanning process is complete, click the “play” button in the player and let the video file playback for a bit. Watch the video and ensure that Aegisub is handling the file correctly.

Aegisub has your movie file and can play it back without errors. This means that the subtitling process can begin. The first step in this process is to obtain a subtitle file for your movie. Head over to our MKVToolNix tutorial and learn how to extract subtitle files from the legal backup of your movie.

Once the subtitle file is extracted to your Linux PC’s hard drive, go back to Aegisub, select “File,” then “Open Subtitles”.

Browse for the subtitle file on your hard drive, and allow it to load into the Aegisub app.

When the subtitle file loads up, Aegisub will automatically set out a timeline with the text and overlay it with the video. To view the subtitles, click “play” in the video window.

Edit Subtitles

Now that Aegisub has the subtitle file in sync with the video file, you’ll be able to edit subtitles in movies and make as many changes to the subtitles as possible. Best of all, since you’re working with an existing subtitle set, there’s no need to tinker with the timing of the lines or anything like that.

The on-screen subs appear in a list, chronologically. Use the scroll-bar and look for a line to edit. When you’ve found the line you’d like to change, double-click on it.

Double-clicking on a line in the list will automatically skip to it in the Aegisub video player. From here, click on the text-area next to the video player and write in whatever changes you’d like to make.

Done editing the subtitles in Aegisub? Click “file” then “Save subtitles as” to save the changes.

What Is The Difference Between A VPN And A Proxy

When it comes to protecting your online privacy, you’ve probably heard the terms proxy and VPN being used. These tools are meant to mask what you’re doing and keep your online activity private. To the average user, a VPN and a Proxy seem to be synonymous. They both essentially do the same thing i.e., keep you safe and hidden online. Some users might just think that a Proxy is another name for a VPN however, that is not the case. There is a distinct difference between a VPN and a Proxy.

Proxy Service

A Proxy service redirects traffic from your computer to an intermediary computer/server, and then routes it to where you intended to go. For example, if you’re trying to visit, and you’re using a proxy service, your request will first be sent to a different computer, and that computer will forward the request to access The data that returns will likewise be routed through that same computer.

Think of it like this; you have two countries that cannot trade with each other due to legal restrictions but both want to import and export products from the other country. In order to do this, the countries will export their goods to a third, neutral country and import items from the other country from this third one. It’s complicated but it gets the job done. A proxy does this but for online activity, it gives users the benefit of hiding their IP address.

VPN Service

A VPN service is far more complex than a Proxy service. It does what a Proxy service does, and more. VPNs add a layer of encryption and security to the data that is sent. They are a collection of servers that work via a client installed on your device (desktop or mobile) and the second you connect to a VPN, all data sent from your device is encrypted.

Your VPN will most likely reroute traffic but it will also encrypt it so that no one knows what you’re sending or receiving. Continuing with the same example of the two countries that cannot trade directly from the previous section, a VPN in that example would be if the two countries were to export goods to a third country. The third country would then rebrand them so that there is no evidence as to where they were originally manufactured from. The goods would then be exported.

Difference Between VPN and Proxy

The major difference between a VPN and a Proxy is encryption. Some proxies claim to hide your IP address, and some do but not all of them are successful against services that do not allow anonymous web traffic. A proxy is a watered down, basic privacy tool that will work in some cases but not all. A VPN is far more robust; it has multiple servers that traffic is routed through and if one server goes down or is blocked, there is always a second server to take its place.

The traffic sent through a VPN is always encrypted and you’re given a second IP address to mask your actual IP address.

A proxy works mostly with web traffic sent from your browser whereas a VPN will encrypt every single request sent from your computer. All background services that need to access the internet such as update requests will also be encrypted. The encryption will extend to all desktop apps and services instead of being limited to just your browser.

VPNs are often faster than proxy services. A good, fast proxy service that promises data encryption and a hidden IP address is a basic VPN service. Proxy services mainly reroute traffic so they have few servers to route them through and thus your requests take longer to complete. VPNs on the other hand have a much larger network of computers that can handle more requests simultaneously thus making them faster.

Because a VPN is a much more robust service, you’re less prone to seeing errors or failed requests whereas a proxy service might not work well or at all if it has too many users.

Picking A Service

By now, you should know that there is a small but distinct difference between a VPN and a Proxy and that should help you decide what you want to use.

A proxy service is best used for low level privacy needs, or when you need to fake your location for something minor like watching a regionally restricted YouTube video. If you’re trying to watch regionally restricted content on Netflix, a VPN is going to do the trick.

This is because YouTube doesn’t go to great lengths to block users who try and fake their location. Netflix on the other hand actively thwarts them and VPNs, the good ones like NordVPN or ExpressVPN, will constantly update their servers and available IP addresses to get around whatever Netflix is doing to keep you out. Similarly, for services like Hulu, Spotify, Pandora, you need a reliable VPN and a proxy simply won’t do.

With respect to privacy, a VPN is always the superior option. Proxies don’t encrypt data and those that do aren’t worth it. It’s better to opt for a VPN that will do all that and more in more or less the same price.

Best VPNs for Comcast: Fast, Secure, Bypassing ISP Throttling

Comcast has steadily slipped out of favor over the last several years. Users cite poor customer service as one of Comcast’s biggest flaws, but the company has been shown to be a big player in political lobbying and is known to engage in billing schemes many users feel are unnecessary and unfair. Comcast is also one of the more outspoken supporters of destroying net neutrality, as well, leading many to fear the company would be one of the first to implement internet fast lanes if given the chance.

Despite its position in the public eye, Comcast is still a huge cable and communications company. Its Xfinity program serves tens of millions of customers by providing both cable TV service and internet connections. While dealing with their customer service and billing practices is almost entirely out of the public’s hands, there is something everyone can do to protect their privacy and maintain net neutrality in the face of Comcast’s questionable practices: install a VPN.

Below we cover the best VPNs to use with Comcast and Comcast Xfinity, including methods to encrypt your data and hide your identity so you can use the internet without giving up your data or your freedom.

How to Find the Best VPN for Comcast

It’s never easy to find the right virtual private network, whatever your needs may be. When looking for a provider to use with Comcast, you’ll have a special set of required features to hunt for, as well. For example, you have to find a VPN with strong encryption and a good privacy policy to help keep you safe from Comcast’s potential data logging and internet fast lanes.

How Do VPNs Protect Me?

VPNs, or virtual private networks, create a sort of tunnel between you and the internet. When you sign up for a service and install an app on your device, data that leaves your PC or smartphone gets encrypted before it leaves your home. This process wraps every piece of information in a layer of unbreakable code, making it impossible for third parties (including Comcast) to see what websites you’re visiting, what streams you access, and what files you’re downloading.

In addition to basic data security, VPNs also provide a measure of online anonymity. Those packets of unreadable, encrypted information are stamped with your IP address, one that can be used to trace activity back to your real life location. By sending them through a VPN first, that information is removed and replaced with a non-local, virtual IP address, one that isn’t connected to your identity at all.

With a VPN active, you can essentially stay invisible online. Your activity remains hidden, your identity secure, and your personal data perfectly private. All you have to do is run a VPN app in the background and you’re set.

Criteria for Selecting a VPN for Comcast

It isn’t easy researching VPNs, nor is it easy to pick the best one to use with Comcast. In the next section we present our recommended providers to help keep you safe online. We used the following criteria to make those selections, ensuring you get the best, most private experience possible, even if you have to use Comcast to access the internet.

  • 256-bit AES encryption – The standard for locking down your data, keeping it safe from prying eyes.
  • Device support – Got a smartphone, Fire TV, or tablet? You’ll need a VPN app to keep them safe.
  • Good download speedsSpeed is crucial when choosing a VPN, as some services can be unbearably slow.
  • Large network – The more servers a VPN runs, the more connections you can utilize.
  • Zero-logging policy – A strict zero-logging policy ensures your information is never stored long term.

Using a Good VPN with Comcast

Once you’ve researched and selected your VPN, the hard part is over. Now all that’s left is to install the VPN on your devices and use them to secure your Comcast internet connection. Follow the steps below and you’ll be ready to go in a matter of minutes.

Step 1 – Download and Set Up Your VPN

Once you’ve selected a VPN, the first step is to get it installed. Choose one of the recommended VPN services in the section above for the best performance, then follow the steps below to add it to your Comcast-enabled device. Note that the process will be slightly different depending on which VPN you signed up with. If you ever get stuck, check your VPN’s support pages for a detailed installation guide.

  1. Sign into your VPN and download the app for your device (Windows, Mac, iOS, Android, etc.)
  2. Install the VPN app on your device, launch it, then enter your account login details.
  3. Connect to a recommended server. Most VPN apps will automatically find the fastest server and connect you to it right away.
  4. Look through your VPN’s configuration pages and set it to automatically connect each time you start your device. This ensures you stay safe no matter what.
  5. Let the VPN run in the background. As long as it stays connected, your identity and your Comcast internet is secure!

Step 2 – Verify Your IP

VPNs are generally pretty reliable, but there’s always a chance something can go awry. There’s a quick method of ensuring your connection and identity are secure, however. Running a quick IP verification test is all it takes to make sure your VPN is operating as intended. This is an optional step, but it’s a good idea to use it the first time you use a new VPN, just to be sure it’s working correctly.

  1. Make sure your VPN is active and connected to a server.
  2. Open a web browser and go to
  3. Wait for the page to load and automatically run an IP address lookup.
  4. Look at the box at the top beneath “Your IP address”. If it shows a country other than the one you’re currently in, the VPN is working correctly.
  5. If the box shows your physical location, check with your VPN provider to resolve any IP leak errors.

Step 3 – Enjoy a Private Internet Connection

Once your VPN is activated, connected, and your IP address confirmed to be anonymous, you’re ready to go. Every time you turn on your device, make sure your VPN is launched and connected to a fast server. You can then open your browser and visit any website you like, secure in the knowledge that your activity is private and your identity hidden, even from Comcast itself.

It’s important to note that if you use multiple devices with Comcast, make sure to install your VPN app on every single one of them. This includes smartphones, PCs, laptops, tablets, and even things like Fire TV and set top TV streaming boxes. You may not think they give up much information, but it’s surprising how easy it is to track someone’s activity on a seemingly innocent device.

Does Comcast Block VPNs?

In the past several years there were rumors circulating that Comcast started blocking select VPNs. Users reported logging into their VPN and suddenly finding their connection terminated, only to see it restored once the VPN itself was shut down.

While the news of Comcast blocking VPNs wouldn’t surprise anyone, the evidence in favor of this is slim at best. No list of blocked VPNs was ever created, and no one who tested the theory could reproduce the results. In all likelihood, a few select users were experiencing other internet issues unrelated to Comcast blocking anything.

So, the short answer to this big question is “probably not”. If net neutrality laws are destroyed, however, this could change. For now you’re free to download and use any reliable VPN service you like and can enjoy full access to the internet through Comcast.


Comcast is a massive company that provides cable and internet connections to millions of customers across the U.S. It has a less-than-stellar reputation as far as customer service and user privacies are concerned, which is why running a VPN each time you connect through Comcast is always a good idea. With the recommendations and tips above, you’ll have an easy time protecting your online identity and data.
