How To Download 3D Videos From YouTube

Lets take a look at some of the easiest ways to download 3D Videos from YouTube to your Windows/Mac computers.

Last Saturday, I received a mail from Getting Geek reader Naina asking me how she can download 3D videos from YouTube.

Hello Getting Geek team,
I have a pair of 3D glasses dusting in my cupboard and I also have a 3D TV in my home. The problem is, there is no way I can connect my TV with my Laptop (the HDMI Port seems to have broken, I don’t want to spend too much in getting it repaired)
I was wondering if there is an easy way to download 3D videos from YouTube  so that I can later copy them to my flash drive and them watch them on my TV.

Ask your questions here.

Sure, Naina has a good question, but before discussing how she can download 3D videos from YouTube, I want to clear one thing : YouTube policies don’t seem to be liking Downloading videos from their website. You should only consider downloading anything from YouTube if you understand these legal problems.
Now that I have given you proper disclaimer, let’s dig into the problem

Searching 3D videos on YouTube

Of course, not all videos on YouTube are available in 3D (creating 3D video is a lot of hassle and computer work, BTW)

download 3d videos from youtube
To search for 3D videos, open YouTube and in the search box, enter the video that you want to download. On the next screen, you will be seeing a list of found videos. To filter out non-3D videos, simply click on Filters and then select 3D from the list.

Now that only 3D videos are shown, you can download 3D videos from YouTube .

You will soon see a list of available resolutions and their file sizes, simply pick any of your choices and you will be good to go.


Using Desktop Applications

If you are using a PC running Windows XP or newer, you should try installing the free version of 4K Video downloader. it is a bit restrictive on features for the free version, but if you are looking for downloading less than 25 videos at once, you don’t really need to purchase the full license.

The same is not the case with videos. Downloading video from the internet can be easy, and it can also sometimes become a bit complicated. It depends on the Video format and also the process varies from a website to website.

Downloading Flash Videos

Flash is ridiculously old technology, but it is still employed in tons of websites. While all Flash videos are played using Adobe Flash plugin, it does not provide any direct option to download the video from the site. To download any flash video from a website, it is much easy to install an Extension for a web browser.

For Google Chrome, you should try Flash Video Downloader. For Mozilla Firefox check-out this.

If you are using Microsoft Edge, you are out-of-luck for now as it does not have support for any browser extension.

Downloading HTML5 Videos

If you are using, Google Chrome or Mozilla Firefox, Downloading HTML5 videos can be easy (in rare cases, I should add). If you are using a website that uses HTML5 videos, you can try to save a video by simply right-clicking the video and choosing “Save As” option from the context menu.

It does not work on all websites, but it is worth a try as it takes much less time.

Saving Videos for Offline Use

What Are Facebook Instant Articles And Why Should You Care

Facebook is huge. Ever since its launch in 2003, Facebook has seen a really exponential growth. With time, the internet has also changed rapidly. The internet hosts millions of web pages and billions of people reading them. Facebook is trying hard to make sure that people spend more time inside Facebook.

You can see this attempt in Facebook’s music sharing features, with lets you buy music on Facebook, it can also be seen in Facebook’s attempt to shopping, now it lets people pay for stuff right on their Facebook feed. Heck, you can now even donate to charities in Facebook.


The reason behind all of that is pretty simple, the social networking giant does not want you to leave Facebook ever. The longer you stay in Facebook, more the company can show you ads and the more it will earn. Facebook Instant Articles are also a big step it this attempt.

Instantly Delivering and Getting Back

Normally, when a user or a page posts a link to any article outside, it looks like a big thumbnail and when anyone clicks on that thumbnail, he or she  taken to the website. Depending on the network and other factors, it can take 10 seconds or more.

For today’s world, it is too slow.

Instant articles try to solve this problem by showing the article right in the Facebook app. It strips down the time of loading a web browser into RAM and connecting to a website. This makes the content consumption fast as hell. Rather than being hosted on other servers around the globe, Facebook instant articles are hosted on Facebook’s servers. This makes retrieval of them really fast. Apart from being fast they look a lot streamlined and they are easy to navigate.


Instant Articles are also great at being interactive, they can have auto-playing HTML5 Video and moving animations. You can tap into any photo to open and zoom upon it. Not just this, They can interactive maps, Galleries and more.

Arguably more importantly, they provide a streamlined minimalist view of posts and articles. It makes it far less unlikely to get lost in tons of menus and banner ads and popups.

Auto-playing videos make it a more immersive experience.

About the future of Instant Articles

It is all great for you. Currently, only a handful of internet websites are using Instant Articles and it is only available for iPhone App. Soon it will be made available for other platforms (Android, Windows Phone) as well and more publisher’s will jump into this bandwagon too.

Publishers are liking it for two reasons,

It makes the Article Load Faster

Every site owner wants its site to load as fast as possible. Google also considers page load speed as a factor when it ranks them on Google Search Results. More importantly, Faster load speed means makes it sure that more people will read the articles and thus it will result in more reader engagement. I also think that Facebook will give Instant Articles an advantage on user feed.

It doesn’t cost a dime and they keep the advertising money

More importantly, optimizing a website for fast load speed can cost money and resources, Facebook instant Articles are completely free to use. Publishers don’t even have to use any rocket science. Content can be published directly through the CMS of the website.

The other important factor is, publishers can show advertising in their articles be they native or tracking based. They can keep 100% of their ad-revenue. If they want, they can use Facebook to show ads. In this case, 30% of ad revenue will be kept by Facebook.

Keeping current market trends on mind, it makes a win-win situation for both.

With the introduction of Facebook Instant Articles, it will start a trend for its competitors. Others will also introduce some ways similar to Facebook to compete with the speed.

There can be one problem for publishers in future. When dozens of apps and services will be offering similar Article hosting services, it may become a pain in the ass for them to sign up for all of them and to  optimize and publish for every app/platform.

Let that be their problem, for readers, it saves their times and makes the web less annoying.

What do you think about Instant Articles? Do you think that they will prove to be useful for Facebook? Share with other readers in the comments below.

What is Hibernate and How to Enable it in Windows 10

it is like normal sleep on steroids.

Hibernate is a good compromise between Shutting down the PC and putting it into sleep. The first one save the electricity and the latter one is good at saving time. Hibernate tries to make a ground between them by saving electricity and also providing a way to make it possible to work from where you left on your PC.

It is not an exclusive Windows feature, other operating system had it for years. However, Microsoft has disabled it by default in Windows 10 and if you have not heard about this before, this may be the reason.

Before learning to enable and use hibernate, let’s first make it clear to ourselves about what it is and why should you care.

What is hibernate exactly?

Hibernation is a process in which the operating system makes a backup of all data on RAM on a file in hard disk and when the next time the PC is started, reads data from hibernation file and continues where you left from.

Essentially, it is like normal sleep on steroids.

Hibernate is much more energy efficient than Sleeping mode because it completely cuts off the power from the computer and while it is slower than sleep mode on getting back to work, it makes the PC start way faster than a cold boot.

It was first introduced in Windows XP. To put a PC into hibernation mode, you needed to hold CTRL key while clicking on Shut Down button on power menu. In Windows Vista and Windows 7 it was made more accessible, it is located next to Shut Down option.

I don’t know what the reasons are, but in Windows 8 and Windows 10, Microsoft makes it hidden by default. You can make it appear again on the start menu (or Start Screen) after digging a bit in the control panel.  Hibernate is a good enough compromise between Sleep and Shutting down your PC.

How to enable Hibernate in Windows 10?

You can only enable hibernate on a laptop or a tablet. You can’t enable it on a desktop computer. For a desktop computer, you can use an option called Hybrid Sleep which does almost the same as hibernating, however, it won’t cut off the power to components.

To enable hibernate in Windows 10, click on the battery icon in your notification tray. You will see Battery percentages and a couple of other toggles.

From here, click on Power and Sleep Settings

enable hiberante in windows 10

On the next screen, click on Additional Power Settings located on the bottom of Settings Window.hibernate in windows

You will them be taken to control panel. On this screen, search for a link labelled Require a password on wakeup on the left sidebar and click on it.

enable hibernate in windows 10

Depending on your PC you may see a Label “Change settings that are currently unavailable” of there is one click on it, if not – move to next step.

Under the Shutdown Settings, you can find a checkbox located next to hibernate. Click on the checkbox and hit the Save Changes button on the bottom of the window.

enable hibernate in windows 10

After saving the settings, you should be able to see an option to hibernate the computer in Power menu of Start Screen and on the sign-in screen.

Remove Unnecessary Chrome Apps

Unlike browser extensions, Chrome Apps are mostly capable of running offline and they are bigger in size. Some of them run in the background even if Chrome is not running. surprisingly, some of them can be removed from the extensions screen. But,  most are not visible on that screen.

Check your PC for malware, Adware, and PUP

If you are too lazy to check through every screen of an installer or you don’t hesitate in borrowing stuff fro internet, chances are that you have some PUPs (potentially unwanted programs) or some malware or some Adware in your PC. Apart from making the computer insecure, they also ruin your web browsing experience via annoying Ads, popups, and toolbars.

There are tons of free and paid antivirus and antimalware on the internet.  I recommend Avast Free Antivirus as it is cheap and it has a strong protection against antivirus.

For the second opinion, you can check Malwarebytes Antimalware. It is also free for on demand scan and the program is easy to use and navigate.


To search your PC for installed Crapware such as PUPs and adware, you can check AdwCleaner or BitDefender Adware Removal Tool. Both of them are free to use.

I am pretty sure that the above steps will make your Google Chrome perforam better. If you have any other adwise or suggestion, don’t forget to drop it via comments.

Phones and tables are already well understood by most people, Chromecast Audio is completely new device in Google Products. Rather than a successor of a pre existing device it is a new first generation hardware.

Yesterday, in an event Google announced some new devices, Two Chromecasts and two new nexus phones. Google also revealed a new tablet called Pixel C.

Phones and tables are already well understood by most people, Chromecast Audio is completely new device in Google Products. Rather than a successor of a pre existing device it is a new first generation hardware.

So, What is Google Chromecast Audio?

In a nutshell, It is a streaming stick which can stream music wirelessly from a mobile phone, tablet (or anything else) to a speaker system. Chromecast audio works in similarly to Chromecast. Both are connected to the receiving device and the signal is sent from another device. There is one major difference between Google Chromecast and Chromecast audio, the former is capable of streaming Videos whereas the latter can only stream music.

You can use the normal Chromecast with a TV and stream videos, Photos or even games to the TV screen. In case of Chromecast audio, it can only be connected to a music system such as home theater or speakers.

Unlike Chromecast, Chromecast Audio includes a Guest Mode. It needs to be powered by an external power source, which is included in the box. Chromecast audio currently supports popular music apps such as Spotify, Google Music and YouTube etc.

Chromecast and Chromecast audio both cost $35.

Which one Should you buy? Chromecast or Chromecast Audio?

It all is based upon your needs, Chromecast is for streaming Video (with audio, of course) to your TV, actually most people will be OK with this.
Chromecast Audio is good for you if you have a dedicated music system in your home.  your music system may already have a bluetooth system, but Chromecast Audio uses Wi-Fi to stream music. Wi-Fi will be more reliable and Faster than Bluetooth. Also the major point is that if you are subscribed to any music service such as Apple Music, Spotify or Google Music, you can easily listen music on music system without any trouble.

A normal Chromecast will work good if don’t have a dedicated music system and you want to stream Video and Music to your TV.

Everything you need to know about Chromebooks

You have heard about em, haven’t you? Chromebooks are essentially lightweight small and cheap laptop notebooks running Google’s Chrome OS.

You have heard about them, haven’t you? Chromebooks are essentially lightweight, small and [mostly] cheap laptop notebooks running Google’s Chrome OS. This is the major difference between Chromebook and other laptops.
Chrome OS is an operating system based on Linux kernel. However Chrome OS is a lot different than most of Linux Distributions and than any other version of Windows. Instead of having dozens of pre-installed Tools, Backup utilities, accessories, Text Editors and other software, Chrome OS has just a web Browser and only a few important utilities. This is what Google has thought about OS of a modern era. Google’s Chrome OS relays heavily on Internet to do tasks. The Results? Chromebooks are a lot faster on startup and shutdown times, are really easy to manage and diagnose and are a lot cheaper than other expensive Notebook PCs.

What you get with a Chromebook?
Chromebooks begin at a small price of $200 and go up to $999 and up for Premium Chromebook Pixel, the fastest (and most expensive) Chromebook on earth. After paying that price you will get a 11 inch to 15.6 inch display notebook. Running mostly ARM Processors for cheaper models. Many models come with Intel Processors. Rest of the hardware will be just like any other Notebook. All Chromebooks come with Wi-Fi connectivity and some also ship with 3G or LTE connectivity options.

Chromebooks: The Showrunner Chrome OS

The main thing differing Chromebooks with other Notebooks is Chrome OS. Chrome OS is basically a Linux Operating system with Google Chrome Web Browser. When Google first Introduced Chromebooks it was just a Google Chrome Browser running Maximized.  All the Apps and setting could be found on New Tab Page. Now Google has made some changes and OS now looks much familiar with a Taskbar on the bottom and a notification area on bottom right side Just like Microsoft Windows. This area hosts several icons such as Wi-Fi and Data management along with a clock and and a button to switch User accounts.
Chrome OS also has some apps other than Chrome Browser. It includes an Offline File Manager that is able to open and preview some Common File Formats. Chromebooks has an offline Music and Video Player too.

Strength and weakness of Chromebooks


  • Easy to use and configure.
  • Low cost and lightweight.
  • Longer Battery life than other haviour laptops.
  • Less risk of Malware and other nasty, No need to install antivirus.


  • Chromebooks are running a different OS and because of that app library is really smaller than the competition.
  • Granted that they can work offline but it is really limited at some task, Internet connectivity is needed to perform most of the stuff.
  • Google Chrome is the only web browser in Chromebooks, you don’t have any alternatives to use.

Chromebooks are good for

People who are most of the time online, who just need a computer to check emails, use social media, do lightweight productivity tasks and who use laptops for entertainment. You can do many things online and this is where promise of google with Chromebooks seems to be true. Due to their simplicity, you can think of them as an excellent choice for older – or not so tech savvy – people.

Chromebooks are not so good for

Granted that most of the work people do on computers nowadays can be done under the tabs of a web browser, still we do need some heavyweight application who sadly run only on full-blown Windows or Mac OS X systems. Chromebooks are good for many day-to-day tasks. If you are into editing heavyweight Video Clips, making complex vector graphics or running professional desktop applications, you will feel trapped with the limitations of chromebooks. Simply put For power users who are happy about maintaining their systems, backing them up and are able to deal with Malware, Windows, Mac or Linux are better options.

If you have already bought a Chromebook and you are feeling bad about the limitations here is what you can do: Install Linux on it.

Linux can easily be installed on Intel Processor based Chromebooks. How to Geek has a good guide to do that.
