Aiseesoft DVD to MP4 Converter for Mac is a commercial DVD ripper. It can be used to convert DVD movies into a variety of formats. The available video formats are MPEG-4, H.264, DivX, XviD, MOV, M4V, WMV, AVI, and WebM. In that list are some of the most popular video formats these days, so you won't have problems playing your movie on multimedia playback devices or PCs or Macs.
To load a DVD movie, you can either load the movie using the disc itself, a folder on your Mac with the movie in it, or IFO files. Once the movie is loaded, you will see a list of all the DVD titles that make it up. You can then select the ones that you want to convert and choose a different format for each title, if you want.
There is a video editor that comes in handy when you need to trim or crop your videos. If you need to touch up properties like brightness, contrast and saturation, you can do that as well. There is support for image and text watermarks.
In my testing, I loaded a DVD movie. I trimmed the main title to a 5-minute long video and selected the default H.264 profile. The conversion process took less than 2 minutes and the resulting file looked great and played fine on QuickTime.
