Change the frame rate/duration of quicktime movies losslessly without using extra disk space or modifying the original. Saves reference or self contained movies.

This program changes the header information of a quicktime movie so that it will play at a different speed and fps. The result is saved as a reference movie (so no quality is lost, no disk space is taken up) or as a separate self-contained movie file, and the original movie file is not in any way altered. The only caveat is that a reference movie needs to have the original around to read data from.

Note: This software may not work properly for all types of Quicktime
