rip + demux at same time

[consultant]

Is there any tool that you can rip a BD and demux it at the same time? Would be like DVD Fab with a demux checkbox. Ideally I'd like to create a FLAC of the HD audio track while ripping. Trying to save some space without losing any quality.

I'd love to see this for BD. I use this feature on DVD Decrypter (IFO mode) (yes I know it's dated but it still works great with RipIt4Me). It speeds up the whole ripping process a ton. Then DGIndex doesn't have to do the demuxing of the AC3 file/or whatever it is (many Japanese DVDs that come with CDs (usually just music videos) have PCM audio).

Other interesting observances:
- RipGuard or ArcOss on almost all adult DVDs, but no CSS (PSL file needed)
- Many adult DVDs mastered improperly (Mono audio, horribly cropped video, etc); almost always interlaced but this might just be because of equipment (I have not found an adult DVD I can do a IVTC on yet, causes jitter, etc)
- RipGuard or ArcOSs on regular DVDs with CSS, especially anime (PSL file needed)

Hi,

eac3to on top of anydvd hd...

this works without problems, but after my experiences there are situations where ripping + demuxxing at the same time is slower then ripping in a first step and demuxxing in a second step. Think of BDs where the main title consists of a set of seperate m2ts files. In this case eac3to mostly is forced to do a second pass when demuxxing to correct the overlapping audio. In this case I found that the overall process takes less time, when I first rip the BD to one physical hdd and then demux it to a second physical hdd.

As everybody knows, a modern hdd has much faster read speeds and seek times than a BD drive. E.g. my preferred "internal" hdd, the ST350041, has a transfer rate of 140 - 70 MByte/s ( outer cylinders / inner cylinders ) and a random access time of 14,6mS. To get the maximum read and write speed, I am cleaning up these drives very often to make sure, that the fastest, most outer part of the platers is used. My GGC-H20L has a transfer rate from 7 - 19 MByte/s ( inner tracks / outer tracks ) and a random seek time of 118mS.

In practice that means: If the title which is to be ripped consists only of one m2ts file, ripping and demuxxing at the same time is ok and is faster, since no second pass to correct overlapping audio will be necassary. But if a second pass is needed, direct ripping and demuxxing makes no sense, since the BD has to be ripped twice in this case. Here the superior read and write speed and the faster access time of two physical drives makes the difference, ripping first and demuxxing second is, at least in my experience, faster.
