From the developer:
DustBuster+ is a professional video editor tool for Mac. An integrated interactive quality control environment ensures the best possible results for your restoration projects. All actions are recorded on a meta-data level, so any changes can be easily re-applied to the sequence any time and the final images are created only when they are really needed.
You may want to check out more Mac applications, such as Aiseesoft MPEG Converter for Mac, STAMPot or Tipard All Music Converter for Mac 2, which might be similar to DustBuster+.
