Article in English: HandBrake is a free program for Windows and Mac computers that can be used to rip an MP4 file from a DVD:  Go to https://handbrake.fr/ in your computer's web browser. Click Download HandBrake. Double-click the downloaded setup file. Follow the on-screen instructions. The DVD should go logo-side-up.  You can ensure that your computer has a DVD drive (not just a CD drive) by looking for the "DVD" logo on the drive tray. If you don't have a DVD drive, you may not be able to rip your DVD. If your computer doesn't have a DVD drive, you'll need to buy an external one and plug it into one of your computer's USB ports. Its app icon resembles a pineapple next to a fruity drink. It's a disc-shaped icon with your DVD's name in the upper-left side of HandBrake. If you don't see the DVD icon, close and then re-open HandBrake. HandBrake will typically default to an MP4 conversion, but you should double-check the following aspects before continuing:   File format — Make sure the "Container" box has "MP4" in it. If it doesn't, click the box, then click MP4.  File resolution — Click Presets, then click a quality (e.g., 1080p) on the right side of the window. It's to the right of the "Save As" text box. A pop-up window will appear. Select a save location, enter a file name in the "File name" (Windows) or "Name" (Mac) text box, and click Save. It's a green button at the top of the HandBrake window. Clicking it will prompt HandBrake to begin converting your DVD into an MP4 file. Once the MP4 has successfully been ripped, you can proceed.  On Mac, you'll just click Start here. DVDs can take anywhere from half an hour to several hours to rip into an MP4 file, so make sure your computer is charged and/or plugged in and well-ventilated. Open VLC by clicking (or double-clicking) its app icon, then do the following:  Click Media (Windows) or File (Mac). Click Convert / Save in the drop-down menu. Click the File tab. Click Add, then select your MP4 and click Open. It's at the bottom of the window. Click the "Profile" drop-down box,...
