"I didn't want to butt into someone else's thread so I thought I'd create this one. I'm curious about the quality of ripped blu rays (and DVD's, but mainly blu). As in will any compress the file size but give a completely lossless film for both video and audio? Or is the best way to do blu ray keep the entire thing so no quality is lost (obviously that could mean up to 50gb per movie). Also if the above is possible will it retain any audio tracks within it, e.g. DTS HD, True HD and standard dd5.1 and DTS?"
If you want to get movies off of Blu-ray discs and onto your phone, tablet or somewhere else, you'll need to first turn the Blu-ray discs into a digital file format on computer - play it wherever you want. The point here is, to rip a Blu-ray, is it possible to do this without any further or additional quality loss? If the answer is yes, then which the best method for lossless Bluray rip? In this post, we'll show you how to rip a Blu-ray with 1:1 same quality, or convert Blu-ray to digital formats with at least 98% of the original quality.
Why does Blu-ray Transcoding Produce Quality Loss?
To address the large file size of videos which contain a lot of data, we use codecs to compress them. The most common codec is H.264, along with many others like MPEG-2, H.265, AV1, XVid, etc. When you transcode a Blu-ray, it refers to a process of taking the M2TS video out of the Blu-ray and re-encoding it with a different codec or different settings.
There are three types of transcoding: lossy-to-lossy, lossless-to-lossless, and lossless-to-lossy. Once the quality loss happens, you can get back the original quality again. So there is no loss-to-lossless transcoding. As Blu-rays are encoded in the inefficient M2TS codec (lossy codec), you're left with no choice but lossy-to-lossy transcoding, which will decrease the quality to degrade even further. This is why you can't rip Blu-ray losslessly with Handbrake. What you need is to rip Blu-ray without transcoding with a proper tool.
