DVD Layers – How DVDs Work- Rip DVDs
It’s amazing when you think about it: you can store a movie data on a shiny piece of plastic no bigger than your hand! Although video/versatile discs (DVDs) have been around for more than 20 years, they are still one of the most popular ways of storing videos. And now we have Blu-ray™, which can store six times more than a DVD! Have you ever wondered how DVDs, and Blu-rays actually work? Let’s take a closer look!
Note: Throughout this article, we’ll talk about DVDs. But almost everything about DVDs also holds true for Blu-ray discs.
How DVD Works？
DVDs are of the same diameter and thickness as CDs, and they are made using some of the same materials and manufacturing methods. Like a CD, the data on a DVD is encoded in the form of small pits and bumps in the track of the disc.
A DVD is composed of several layers of plastic, totaling about 1.2 millimeters thick. Each layer is created by injection molding polycarbonate plastic. This process forms a disc that has microscopic bumps arranged as a single, continuous and extremely long spiral track of data. More on the bumps later.
The lack of DVDs is the inconvenient playback. DVD playback relies on DVD Player but portable devices such as iPhone 7, Galaxy Note 7 don’t have one. So if you want to play DVD movies on portable device, you have to rip DVD on hard drive. Ripping unprotected DVD is easy because nearly every one know Handbrake. Handbrake can rip DVD to MP4with 3 clicks. However, commercial DVDs have encryption including CSS, region code, RCE, Sony ArccOS, UOPs, Disney x-project DRM, etc, which Handbrake can’t handle. In this case, you have to turn to a closed-source called Pavtube ByteCopy.
Comparing with other DVD Rippers, Pavtube ByteCopy can decrypt any protected commercial DVD, even Blu-ray to hard drive. It can 1:1 backup DVD to hard drive with original video structure. It also can main title copy DVD to VOB files with smaller size. If you want to play DVD on WMP, QuickTime, or iPad Pro, Galaxy Note 7, ByteCopy can convert DVD to WMV, MP4, 3GP, MKV, H.265, M3U8, AVI, MOV, M4V, etc.
Step-by-Step to Rip DVDs
Step 1: Load DVD movies
First, insert your any DVDs including Disney DVDs and online DVD rentals into DVD Drive, and then drag the DVD files to the program; Or you can get to “File” Menu, click “Load DVD” to draw into DVD movies you want to rip. DVD folder and ISO image files are supported as well.
Step 2: Select output formats
Click the Format bar to select output profile say “H.264 HD Video(*.mp4)” from “HD Video” is the best choice. This format will be playable on iPad Pro, iPad Mini 4, iPad Air, Galaxy TabPro, Galaxy Note 7, Galaxy S7/S7 Edge, etc.
Tip: Click Settings bar, you can adjust the level of compression to suit the quality you want. If you prefer a much better video quality and don’t mind the output file size, you can rise the video bit rate higher. Generally speaking, the higher video bit rate will result in the larger output file size, and vice versa.
Step 3. Convert DVD movies
After all necessary settings, you can just click the “Convert” button to start converting your DVD movies. After the conversion, click Open to get the output files.
You can keep the DVD rips on hard drive. You also can store the DVD movies onto Synology NAS, Seagate Wireless Plus, HP MicroServer Gen8, Personal Cloud, etc then you can stream DVD movies on DLNA-enabled devices wirelessly.
