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... |

Minimizing the size and "lossless" compression are two contradictory goals - a true lossless compressor will never achieve the same compression ratio as a lossy one. If the compression ratio that lossless compressors can achieve is not sufficient for you, you'll have to go with lossy compression... Quote:
Note, however, that if you don't require "true" lossless compression, but only "perceptually lossless" compression, then x264's CRF mode with a low CRF value will do job. ...and give you a much better compression ratio, compared to a "true" lossless compression.
