While you want to make a rip of a DVD for private use like for playback on HD TV or PC, you will be probably uncertain about the correct aspect ratio. What would be the correct resolution for a full-DVD-quality rip in the correct aspect ratio at maximum resolution? 720x400, 720x300 or other? What are the best fit for 16:9 widescreen and normal 4:3 display? In this page, we will give you some hints.
As you know, there are two aspect ratios supported by DVD: 4:3 (also called "Normal" or "Full Size") and 16:9 ("Wide Screen"). Both aspect ratios use the same picture size; however, the 16:9 (widescreen anamorphic) image is horizontally compressed on DVD and then stretched by the DVD player when viewing.
4:3 is the aspect ratio of a normal TV (Image 1). 16:9 is the aspect ratio of a widescreen TV (Image 2). A 16:9 feature will be letterboxed on 4:3 TV (Image 3) or Pan & Scan (Image 1).

Step 1: Load DVD movie source
Launch the DVD ripping program, but before doing this, make sure there are no other decrypter tool running at the same time and make sure the Internet connection is fine. Insert your DVD disc into DVD drive. Then click the DVD disc icon to load DVD movie. If your DVD is saved as files on your computer, click “DVD Folder” and browse to the folder that contains DVD files.
Step 2: Choose a proper format
Click the Format bar, and choose a desired format. For playing common DVD rips (720*480 for NTSC, 720*576 for PAL) on HDTV, AVI, WMV, MP4 from Common Video profile list are the highly recommended output formats.
Step 3: Set best aspect ratio for 4:3 or 16:9 display
A. Best video display ratio for a 4:3 display
If your display screen or HDTV is in 4:3 aspect ratio, here you need to set nothing. The default settings will result in letterboxed DVD videos with black bars above and below like the below image (720*480, 4:3) shows.
B. Best video display ratios for a 16:9 display
The videos created using the default format, however, does not look great on a 16:9 display. *If you want to get a 16:9 display and don’t mind the stretched picture, you can click the Edit button to enter the Video Editor -> Crop. You can select the output mode as Stretch.
Tip: Keep in mind that when it comes to DVD movies there is a formatting issue to consider. Many movies are wider than 16:9. For example, Seabiscuit, The Lord of the Rings, Dances with Wolves, Tombstone, The Fifth Element, U-571, American Beauty, and Star Wars/Phantom Menace (to name a few) are all 2.35:1, not 1.78:1. When you display these movies on a 16:9 screen you will have black bars at the top and bottom of the screen, each bar amounting to about 12% of the picture height. The bars are not as large as they would be on a 4:3 screen, but they are there nevertheless.
How to Get the black bars off?
In the Video Editor interface, here you see the Original Preview and Output Preview area. The original video is put in green frame. Drag the dotted frame to crop black bar out as it shows below.
Additional tips: To avoid black bars when play DVD videos in full screen, you may click “Settings” button to set a video size of 16:9 in the “Settings” panel, for instance, 720*405, 800*450, 960*640, or 1280*720.
Step 4: Start converting DVD
After the settings, click the “Convert” button to start converting DVD to desired size (aspect ratio) for playing on (HD) device.
