Think of converting to h264 from bluray the way you would have converted dvd to divx in years past.
They can look very good but won't be the same as the original version.īluray backed up to bluray media will be much closer to its original form - compressing to bd25 from bd50 should keep it close to its original form with minimal reduction in quality while maintning features. The original codecs used in bluray are very large and in order to compress to a dvd dual layer for "bd9" discs you need to reencode it - change the quality. It has more and more acceptance in playback devices like a ps3 or a wdtv media player - or a bluray player when authored as an avchd. Why ? h264 has an excellent compression ratio for high def source material.
#Bd remux movie
The movie after remux often has H264 video codec.
The orginal movie has AVC, or VC-1 video codec. I don't intend to backup my Bluray disc in computer, just want to resolve my doubts. But i dont understand: the orginal movie has AVC, or VC-1 video codec. They said Remux will keep orginal quality. And the size of movie after remux isn't too small to orginal disc. With this method, they can choose to keep disc menu or not, and remove some unnecessary stuff like some audio streams. If the quality cant be keep, why don't call "Encode" or "Rip" ? So, will this backup method keep orginal quality of movie? I doubt that, because the size is too small (9GB) to orginal BD disc. They shrink one Bluray disc (about 40-50 GB) into 25GB, and enven 9GB (they call: BD 9). I see somebody backup their Bluray movie in HDD computer, they call "BD Re-encode". I have some questions about bakup Bluray.
