Consumer Camera Video Samples - Where can I find them?

Hello, this is my first post, I apologize if this has been asked already, or if this isn't the correct forum.

Does anyone know where I can find common consumer camera and phone video samples? I see the below link that has video samples for viewing on the web, but I'm looking for the actual video files themselves, from the camera or phone.  There are many sites out there that compare DSLR ISO performance taking the same picture with differnent cameras, I'm assuming there must be a site out there that does the same for video where you can download the original video file?

This is to test trimming different video formats, it would actually be great to find video clips from different camera formats, of people talking, so I can test that the video and audio are in sync after trimming the clips.  I know that's a stretch, just throwing it out there.

Thank you for the help!
