content: For anybody that doesn't want to rely on third-party software for saving non-flash web video files:   Often you can just right click the video and save.    In Firefox based browsers you can go to about:config settings and change the setting 'media.mediasource.enabled' to false, then File > Save Page As > Web Page, complete(The video file will be in the web page folder you saved), or just find the video file in the browser cache folder in your file system(I found this method somewhat unreliable for big video files for some reason, the video files were broken into many different files).    You can right click a web page then View Page Source and often find the .mp4/video file URL with Ctrl+F  in the source code of the page. Copy the video url and then save it with one of the aforementioned methods.
