It was mildly amusing to me that Citizenfour.7z is 11MBytes (.9%) _bigger_ than Citizenfour.mp4.
It would have been quite a shock if any AVC CABAC .mp4 video could be compressed by 7z (or any other lossless compression algorithm). AVC CABAC utilizes arithmetic compression for its lossless compression portion, which is very, very good.
