What is DVDxDV?
DVDxDV is a program that can extract the audio and video from a DVD. This is the reverse process of the DVD authoring or creating a DVD.
DVDxDV creates a Quicktime file on your computer that is a copy of the video on the DVD. This file used to share with others, edited into a new video, or even burned on to a new DVD.
How is DVDxDV better than just using ffmpeg or another extraction tool?
DVDxDV is easier to use than a command line utility like ffmpeg. You simply insert your DVD into your MacIntosh, and DVDxDV will display the video that is stored on your DVD. You can then select a video clip and extract it to any Quicktime supported format.
DVDxDV will preserve the original look of the video. A single video frame is made up of two smaller parts called fields. These fields can get can lost with other DVD extraction programs, causing the picture to look very bad when viewed on a television screen. DVDxDV is capable preserving these fields, so that the video will look smooth if it is played back on a television screen. In order to do this, you must extract the DVD video to a Quicktime format that supports interlaced video, such as DV.
