[Hot News]Best Backing up Blu-ray Movies Software-seek a balance between video quality and file size

Movie lovers can easily find how delicate and brittle the blu-ray disc is. It is almost impossible to protect blu-ray discs from scratches caused by frequently uses. And that??s one of the most important reasons why so many people would like to have a copy (backup) of their blu-ray discs. Blu-ray contents, as we know, take ups much more space than DVDs. How to seek a balance between video quality and file size? This article may give you some hint.

How to back up an unprotected blu-ray disc?
In order to back up blu-ray disc, you should have a BD drive that can read the blu-ray disc. Backing up an unprotected blu-ray disc is as easy as copying video files from a data disc. All you need is to connect BD drive with PC, place the blu-ray disc in the BD drive, open its root directory, find BDMV>> STREAM, and copy the *.m2ts clips to your hard drive. If you??d like to burn the disc to another blank blu-ray disc, just copy both the BDMV and BDAV folder to your hard drive and use blu-ray authoring software like Imgburn (freeware) and Nero 10 (shareware) to burn the data to a blank blu-ray disc.

How to back up a commercial blu-ray disc?
Backing up a commercial blu-ray disc is much difficult. As we all know, commercial blu-ray discs are copy-protected. AACS copy protection scheme was initially used to protect commercial blu-ray movies, but soon AACS was cracked, so the Blu-ray Disc Association turned to BD+ technology. BD+ is extra DRM on top of AACS and had not been fully penetrated prior to this. To copy movie from a copy-protected blu-ray disc to your hard drive, blu-ray ripping tool that is able to crack AACS and BD+ protections is required. Among the top blu-ray ripping software, PavtubeBacking up Blu-ray Movie Software is favored by movie lovers for its intuitive interface, excellent decrypting ability, and multiple blu-ray backing up solutions. Users can either make full back up of a commercial blu-ray disc with one click or copy blu-ray movie to MKV, MP4, AVI, WMV, MOV, DivX, Xvid, H.264 video at 1080p, 720p, 480p and more.

Blu-ray backing up: Seek a balance between video quality and file size
Provided that you have a 2TB Seagate external hard drive or Windows Media Server, you may copy all the blu-ray movies to the hard drive using ??Full Disk Copy?? facility and enjoy the blu-ray movie without any quality loss. TrueHD and DTS-MA audio can be retained as well. Notice that a very powerful PC/ HTPC/ media player is required for playing decrypted M2TS files. If the videos play jumpy, try cutting down video bit rate when ripping the blu-ray disc.

For those who want to save storage, a useful tip is converting the blu-ray movie to H.264 encoded MP4/ MKV/ MOV videos. The H.264 is the most efficient method for compressing data so far and it creates video of smaller size and relatively high quality. To further shrink the output file size, you may click ??Settings?? button and set video bitrate down. Output file size is displayed at the bottom of the interface so you can try different settings till you get a desired file size. For instance, while backing up a 20GB blu-ray movie to hard drive, I select MPEG-4 encoded HD MP4 (1920*1080) as output format, and the file size is 16GB. When I select H.264 encoded HD MP4 (1920*1080) instead, the file size is reduced to 12GB, when I set video bit rate down to 6mbps, the file size is cut down to 8G, and the output video is still at high definition quality.
