h264/x264 encoding

how does one encode 25min anime to h264/x264 and get an encoded file smaller than 130MB when not screwing up quality?

This is how it's done:
First, you must realize that zero is nothing. Nothing is useless, so I strip all zeros out of the binary data.

After that, all that is left is a very long string of 1's. This string is compacted to a single 'one', along with a number indicating it's length. Then I add my signature and some other overhead, including a bit of random data to give a unique hash, thus ending up at between 2-16kb of compressed data.

I call this CAR, for Compress and Add Random.
