Editor: If you've ever done commercials, or worked with doing music for video, then you know how difficult it can be figuring out just what BPM (tempo) to use, and how long it will be. SongTime is a down-and-dirty little app to take the drudgery and guesswork out of figuring it out! Just run SongTime, enter in the BPM, Beats/Measure, and number of measures, and it will tell you not only how long it will be, but also Frame and keyframe times as well. Then, just play with the BPM or any of the other parameters, until the time is right where you want it. Both GUI and commandline version of this utility are available.
