What if you have no backups or still missing some videos? Let me tell you something. You are not gonna go out of options ;)
There are bunch of free and paid software to help you with downloading YouTube videos. But I'm not gonna take that route here.
You don't need any third-party softwares or add-ons to download your uploaded videos. Now, YouTube itself allows you to download your videos. Sounds nice and easy? Yes, it is.
Not Only for the Worst Scenario
Not only when you lost your videos, but also I can think of another scenario where this download option may come in handy.
Did you edit or create your videos with YouTube? If so, you already know that the changes will be applied to your uploaded videos hosted on YouTube servers and you don't have them in your storage devices. What if you need a copy of those videos? Now you know what I'm talking about.
There could be more such examples that download option might be useful. Think about it. Let everyone know. Hmm... Now it's time to proceed and find out how easy it is to download a video from YouTube ;)
1. Sign in to YouTube.
2. Navigate to Video Manager.
3. Locate the video you need to download and click drop down button right next to the Edit button.
4. Now click on Download MP4 option and the video will start downloading in a moment.
