The first site is Viewpure. All you need to do is paste the URL from YouTube and it will "purify" the video and eliminate the distractions on page.
Below is a GIF of how to use Viewpure followed by the same 20 second YouTube video (with audio).
The second site is Watchkin.com . This site is great as it will clean-up the video (like Viewpure) and eliminate the distractions in a "family-friendly" environment. You can simply paste the URL and the video will be shown in a clean "safe" environment.
What I really like is the search feature that Watchkin scans the content and will block what they feel is not "family-friendly".
Below is an embedded GIF showing how to use the search feature as well as the same video below on YouTube with audio.
