The demand for getting a good DVD ripping software and DVD converter is increasing, since more and more people need to convert DVD formats into other formats. Various DVD rip tools are available in the market. How to judge a DVD ripping software for its quality? What are the essential features to be checked before buying a DVD ripper? This article gives you information about things to look for when buying a DVD ripping software.

1. User friendly software: DVD ripping software should be easy to operate and use. All the features should be accessed easily without any hassles. It is best to first use the trial versions, if available, and only after you are satisfied with the DVD ripper, buy it.
2. The conversion speed of the software: Any DVD ripper you buy should be able to convert the files in a faster way. If it fails to do so, then it is not a good DVD ripper. Generally the time taken to convert a complete DVD files is half the length or total playing time of the original DVD file.  Let’s face it if it takes over an hour to rip an hour of recording off a DVD, then it is not rip quick enough.
3. Ability to convert to any video format: The DVD ripping software you chose to buy must convert DVD video files into all other famous video file formats, such as MOV, MP4, PSP, AVI, etc. If your DVD ripper does not support conversion to these formats then it is not worth for buying it.
4. The quality of the converted video file: DVD ripper should be able to convert both low quality and high quality videos. The quality of the video depends on the Bitrate manipulation value. For high quality videos bitrate should be kept high and for low quality video ripping the bitrate should be low. Generally bitrate refers to the quantity of information that can be stores in one single video frame.
5. Aspect ratio and the resolution of the converted video file: DVD rippers should allow you to fix or set your own required aspect ratio and resolution of the frames. If you are not able to alter this, then you have to think about buying that DVD ripper. This option is very essential because absence of this option may lead to the output file to be in a stretched format or distorted format.
6. Capability to encrypt and decrypt any copy protected DVD: Some DVDs may be copy protected, which needs to be decrypted first to remove the copy protection. Once the DVD is decrypted, then it should be converted and compressed to your required format. Mostly all the present DVD ripping software have this feature, but it will be safe to check one for this feature before buying it.

These are the main and major features that need to be checked before buying any DVD ripper.
