Video compression is different from file compression because it is a “lossy” compression, meaning you can not get the original video back once it’s compressed.

There are many factors that go into how a video is compressed, some factors are video resolution, frame rate, bit rate, codec and file format. This doesn’t include how the video is shot, just the hard decisions that come with shooting video. On the image acquisition side of things, lighting, camera movement and framing can all have an effect on file size and compression.
