A run needs memory, more the longer the fit and the track, and the longer a voice or the video's own sound, which are read to their end even where they run on past the fit: a 10 minute fit of a 10 minute track took 0.9 to 1 GB, 1.2 GB with --video, 1.4 to 1.5 GB with --voice and 1.7 GB with a voice and the video's own sound, and a 20 second fit took 0.8 GB with a voice that ran on 10 minutes past it. --length is the video's length: seconds (32), frames (960f, at --fps) or minutes (1:05). --hit is the second the drop should land on, for example the logo reveal.
