It's kind of insane how far compression technology has come. I still remember back in the 90's playing with a compression program written in QBasic that could cut your files in half and that was amazing back then, but now a video file can be reduced to a literal hundredth of its original size. The one inaccuracy in what Tom said was that it was lossless. Parts of the compression are, but the majority of it is lossy and information about the image data is lost. It's not as much as it used to be, but enough that multiple edits can lead to compression artifacts becoming more prominent than they otherwise would have been.
