Hello if i embedded videos from all famous video sharing websites and put on my website would the page be penalized by Google because of duplicate content?
Video is not matters for Google .. Just put some different title and unique description for that videos then no issue
May be you can have a link credited to the source of the video. Also, make sure it is not copyright protected.
If it cause penalty then Google never allowed Youtube to provide Codes to embed Video in your websites. There are some guidelines for every video, make sure your read them first.
Nice answer Allow me to add that dupe content doesn't incur a penalty as such, but if you have NO unique content then don't expect to rank for anything. @Puneet Singh I would avoid just changing titles because that sounds like you are stealing content and changing it to pretend it is your own. Google HATES this.
Google only indexes text and the content of your website and its not important for Google images, flash items or videos on your website. Google web crawler only cares about content and if you insert duplicate text on your website even with thousands of images and video, this page will be marked as duplicated page for Google.
