BD-R 25GB discs are within my reach, comes out to $3.00/disc, 50Gb on th eother hand are very expencive. Are most of the movies that are on BD are 25GB or the 50GB?
Thank you for any advise
Depends.. what do you want to do? Do you just want to back them up completely? Do you want to just make digital copies for use as a Home Media Server and be able to play them on DLNA devices or just hold them as backup? Are you willing to sacrifice audio quality?
Two ways about it.
If you want to create an identical replica of your Blu-ray movie on the hard drive as backup only with no network playback on DLNA devices you can do simply the following:
1. AnyDVD HD to hard disk
2. Use BDClown (includes TSMuxer)
3. Pick off audio and stuff you don't need and just keep Video and Audio track and mux it all back into new Blu-ray structure or ISO file or a simple M2TS file.
If you want to make the files playable on your HTPC you should do the following:
1. AnyDVD HD
2. Demux files into mkv and FLAC or AC3 640kbps|DTS 1.5mbps core
3. Use meGUI (alternatively) to re-encode your mkv file into CQ (Constant Quality - with 20 setting). meGUI has FAST/FASTER/FASTEST setting as well. I use FAST setting and CQ at 20 because this gives me absolutely identical quality to Blu-ray video track with much higher bitrate but the size is half of what the original is. Trust me, I literally checked frame by frame of re-encoded video vs original in Photoshop before I settled on this setting because I didn't want to lose any quality. FAST setting will re-encode a movie in about 10-20% more time than what the actual play time of the movie is. So for a movie of 1 hour and 30 mins I re-encode in about 2 hours. This is on an 8-core Mac Pro (2008 model) but it's also similar time on my i7 3.0ghz (which is quad-core but with 8 threads).
4. Once my mkv is re-encoded I use Haali MKVMerge and take the FLAC or AC3 or DTS-Core audio track and mux the re-encoded mkv file and the audio track. This process usually takes about 10 mins.
Now keep in mind, I personally keep 2 copies. One copy is with MKV video, uncompressed and FLAC audio tracks. My playback versions of the movies for use with Xbox 360 Windows Media Center or PS3 are all encoded as AC3 640kbps 5.1 audio (which is either directly extracted from TrueHD tracks) or decoded with ArcSoft Total Media Theater decoder through EAC3TO and encoded with libAften to high quality AC3 640kbps but directly from DTS-HD/DTS-MA/LPCM tracks so I keep the best audio mix possible.
Don't forget. Audio tracks on Blu-ray movies are NOT DRM-ed. So you can use EAC3TO program to directly rip audio tracks from Blu-ray movies without AnyDVD HD if you need to extract the audio for some reason down the road.
