Is there any video compression lossless technique?

Hello, I have a bit queer question. :)

I want to compress very high motion HD (1080p) video, which is uncompressed and really big by size (about 10 GB). but I need highest quality, I mean exactly the same video as source, with no any loss. I nead the same pixel-by-pixel video, but with minimum size.

I have tried many software, (Xilisoft, Squeeze, Episode, AME...) encoded with x264, but however there was a bit loss, and I was disappointed.

shortly:
Is it possible to compress the video to minimum size with no change of quality?
Is there any lossless compression codec or lossless compression software or something else to do this job?

Please, give me any advice.
Thanks...
