iAnalyse will allow you to quickly synchronize the pages of a score (or PDF images) on a video or audio file.

You can draw annotations (graphics, texts or images) on the score, the fade in and fade out of these annotations are also synchronized with the audio file.

Moving a cursor on the score to the rhythm of music can be drawn very quickly. The fullscreen and export (images or Quicktime movie) functions allow you to show or distribute your work.
