Stomp

The majority of video conversions done today are done to adapt the dimensions of a sequence to those of a particular device, such as an iPod or an iPhone, or to reduce its size so it can be uploaded to the Internet.

The strong point of Stomp is the conversion presets that include and, in just a couple clicks, allow you to convert one or many videos to different formats. If the presets don’t adjust to your needs, you can always create new ones with personalized features. This is the only way you can activate the option to cut and select the area of the video you wish to conserve.

With support for processing batches, Stomp also allows you to apply the available filters to the OS X Core Image technology, like: blurs, color adjustments, generators, distortions, etcetera. It’s also possible to extract the audio from a video.

Two free conversion tools for Mac that you can also try are: MPEG Streamclip y ffmpegX.
