In order to most easily convert MOV to VOB files, you will likely want to utilize a program that is specifically designed for video file conversion. There are a number of different programs that can be used to achieve this conversion, though they can vary in price from freeware to licensed software. You might also want to consider the various other features that such programs may provide, such as allowing you to edit the file before you convert MOV to VOB and the ability to burn the resulting VOB to a digital versatile disc (DVD).
To convert MOV to VOB, you typically want to use a program that is specifically created to allow conversions of video files from one type to another. A MOV file is a file that is created to play in Apple™ Quicktime™ and though it can potentially be played in other media playing programs, it was primarily developed for Apple™ players. MOVs typically contain both video and audio data, though they can be used to create slideshows of still images as well.
VOB files, on the other hand, are video object files that were created for use with DVDs and DVD players. These files often contain video and audio information as well as other data that can help create menus and other features often found on DVDs. To convert MOV to VOB, you should use a program that will allow you to convert these file types as easily as possible and take advantage of the options provided by VOB files.
There are a number of different programs that can be used to convert MOV to VOB files and you should find one that works best for your needs. Such programs can be free to download from the Internet and use legally, or they may charge a license fee. While different programs will offer different features, freeware programs typically have less functionality than those for which you have to pay. If you only need to convert MOV to VOB once or twice, or do not need other features, then a free program may work well for you.
More expensive programs that can convert MOV to VOB can often provide a number of other features as well. Some of these programs will allow you to make changes to the video during conversion, such as cropping the video or separating a single MOV file into several smaller VOB files. Many of these programs will also allow you to choose the resolution and display size of the converted file. If you wish to convert MOV to VOB in order to burn the resulting files to a DVD for playback in a DVD player, then you may want to find a converter that will also help you create and burn a DVD.
