FLV2iTunes is a video and audio converter for the Mac. It was designed to be an easy way of converting your FLV files to audio and video formats that iTunes can recognize and play. The app is has a single window with three different tabs from which you can configure both the conversion process and what happens after conversion.
The first tab is video, where you can change the settings for video conversion. There is a drop-down menu that lets you choose between two formats: MPEG-4 and H.264. Below there are three buttons that you can use to resize your video, with two available resolutions and a button to tell the app not to resize at all (I like this option). You can also change the aspect ratio and use a slider to change the quality. There are three settings: low, medium and high. The audio tab only lets you set the quality and to select between audio pass through or force to stereo. From the "Others" tab, you configure what happens after a file has been converted and how the conversion is done.
Unfortunately, FLV2iTunes seems to be broken. I got an AppleScript error when I first launched the app, and a few different errors when I tried to convert a file.
