This is an easy YouTube Video Downloader - if you need is a simple, fully featured and non-intrusive Add-on to download YouTube videos with HD support, seek no more.
YouTube Video Download - YouTube HD Download (1-Click) is a great Download Helper Tool that works great in combination with Video DownloadHelper, Flash Video Downloader and others.
How it works ?
A simple red button is added to YouTube video pages, which enables you to download videos.
The button is integrated in a simple manner below the video and next to other YouTube buttons (see screenshots).
Click the button to populate a list of available formats to download and choose the one you want.
HD video support (with sound)
To get full support of HD videos and to overcome YouTube's technical limitations, a tiny helper app must be downloaded and integrated with this Add-on.
Once the helper app is installed, you will be able to download any desired quality - 8k/4k/1440p/1080p/720p/480p and more.
Check the screenshots to see how to download the helper app.
(You don't need to run or use the helper app directly, the Add-on will handle everything for you, making the experience much nicer.

Technical info - Q&A
Q: Why do I need the helper app to download HD videos with sound ?
A: HD videos with sound are no longer available as a direct download from YouTube. YouTube support them only through DASH (Dynamic Adaptive Streaming), which means the video is split into 2 separate files - video and audio and are required to be merged together to get a fully watchable video.
To merge video and audio, it requires special tools like "ffmpeg" or "avconv".
That's what the helper app does, it uses "ffmpeg" to merge the video and audio together in the background (once they finish to download) and notifies you once it's done!
Q: Can I merge video and audio myself without the helper app ?
A: Ofcourse. You could choose not to install the helper app and do these merges yourself, there are plenty of guides on the Internet on how to do it.
(You would have to download an HD video with no sound and its audio counterpart - you could do this via the Add-on as well).
But it's alot of hassle and why would you if it can be done for you in the background ? :)
Q: Can I use the helper app on any OS (operating system) ?
A: Currently, only Windows 7/8/10 is supported; Mac and Linux support will be coming soon.
Hope you enjoy it!
More features and customization options coming soon!
