I know most of the people would not get agree on my this statement that you can find quality videos at metacafe.com but after visiting this site people would be agree to it. They have all sort of videos and they have describe and separate them related to their type for example in after opening the page you will get all general videos and after searching the content in the search bar if the video type is related to adult rated content like if it has some sexual content or rage or violence in it which is not appropriate for kids, than it will not show it, and then you will have to click the category adult/18 plus only then you can find and watch those videos unlike other similar websites metacafe has made it very louder and clear that they want only quality videos and if the videos do not follow the guideline they have set, they will just put it in the relative catagory.
They show real timeline in the video, and very useful in that matter so you can decide whether you have to watch it or no, website is very light and does not take long time to load.
