Frankly, you need to spend more time researching this subject to understand what you asked for. There is such a thing, but best reserved for scientific endeavors such as video you'll never capture again. The goal with such is "lossless" and the compression can be simply the use of WINZIP or such which is lossless.

-> For the normal home video user, MPEG and other compressions are LOSSY. That's how it works.

http://www.moviecodec.com lists other CODECs you can try to recompress your video works and see if you will be happy.
