1. YouTube

YouTube is known as the No. 1 free video site to most . Originally created in 2005, YouTube has become part of people's leisure life. Everyday, there are plenty of people asking questions like "How to watch YouTube/videos on Nexus 7 1/2 (Kindle Fire)" and "How to convert YouTube videos to iTunes" on question & answer sites such as Yahoo Answers.

As the best free video site to watch and download videos for free, people can enjoy videos with ease as long as there is an Internet connection available. Also, people can make and upload personal videos to YouTube, making it both an affluent video aggregation as well as a social community. Videos on YouTube come in various types: music videos, movie clips & movie trailers, educational videos, adult videos, personal works, presentations, exquisite advertisements and the like. Refer to post if you want to download free videos from YouTube for offline playing.

2. Metacafe

Metacafe is another famous online video site, also known as the world-wide largest independent video site after Google's purchase of YouTube in late 2006. Compared to YouTube, Metacafe emphasizes much on the video quality instead of quantity. Categories covered by Metacafe include movies, videos games, sports, music and TV. Metacafe aims to deliver "entertainment-grade" video content to users and it is reported that only 10% of the uploaded videos are accepted on average.

3. Dailymotion

Dailymotion, a free video site based in Paris, is the second largest video website in the world (second to YouTube). Dailymotion makes it easy to find free video clips with a nicely organized home page. Most of the free clips on Dailymotion are less than four minutes. Videos at DailyMotion can be easily found as well by an array of categories or channels, which is more efficient than today's YouTube. Personally, DailyMotion contains more free adult vids other its peers.

4. Vimeo

Although Metacafe and Dailymotion both claim to focus on vidoe quality, Vimeo is the ultimate home for high-quality videos and has got large numbers of followers. As an open platform to watch free videos, most videos on Vimeo are also user-submitted. However, you may be disappointed if you reckon it as a regular video site and plan to find popular music/videos or movie trailers there. Oppositely, you will find yourself addicted to the awesome HD video shots made by the top directors and animators in the industry. The larger display and higher resolution coming with Vimeo videos ensures the excellent watching experiences on mobile devices in different sizes.

5. IMDb

IMDb, one of the world's most popular and authoritative source for movie, TV and celebrity content, as well as one of the best free video sites like YouTube, has grown into a site that offers movie trailers and free clips from popular talk shows. There are also full episodes of TV shows that can be watched at IMDb. As a free video streaming site to watch movies, both full-length movies and short films made by up-and-coming directors are provided in large amount.
