She wanted to know if there was a way of determining whether a video acquired from an online source (say, YouTube or Vimeo) was the original video, i.e., what the camera shot.

I said that services like YouTube and Vimeo usually re-compress the video for Internet playback, so if one captured the playback, it'd definitely be different. But, some services allow people to download the original uploaded video.

So, I'd like to ask everyone: Is there some characteristic (like bitrate) that we can check to see if the video is the "camera original" or if it's been processed by something else?
