FFmpeg (Mac OS X) 4.3.1

FFmpeg (Mac OS X) is a complete solution to record, convert and stream audio and video.

It is a command line tool to convert one video file format to another. It also supports grabbing and encoding in real time from a TV card. The command line interface is designed to be intuitive, in the sense that FFmpeg tries to figure out all parameters that can possibly be derived automatically. You usually only have to specify the target bitrate you want. FFmpeg can also convert from any sample rate to any other, and resize video on the fly with a high quality polyphase filter.
