Aiseesoft Blu-ray to MP4 Ripper for Mac allows you to rip your Blu-ray and DVD movies to a few formats that use the MP4 container and to other formats as well. The supported output formats are H.264, MPEG-4, MOV, M4V, DivX, XviD, WMV, WebM and AVI. The application also has a lot of conversion profiles for devices like the iPhone, iPod Touch and iPad, Xbox 360, Playstation 3 and PSP, and other mobile multimedia playback devices. The supported formats are very popular, and most devices will probably be able to play the files that you convert using this app. There is a dedicated conversion profile list for HD formats. These are basically profiles with higher resolution, which can come in handy because Blu-ray movies have a resolution of 1080p. You can click on "Settings" next to any video conversion profile to change individual conversion options. In the new window that pops up, you will find the resolution drop-down menu, from where you can change the desired resolution.
Using this application to rip your Blu-ray movies couldn't be any simpler. And if you have ripped a DVD before, you will be familiar with the process. You simply need to select the title that you want to rip and select an output format, and that will get the process started.
I converted a sample title to HD H.264 and I was amazed at how good the resulting video looked. I didn't see any noticeable decrease in quality and the file played very well in Quicktime.
