Lossless Framerate Converter Changes the frame rate/duration in quicktime movies without requiring extra disk space or altering the original. This program saves self-contained movies or reference movies.
This program modifies the header information for a quicktime movie to change its speed and fps. The result can be saved as either a reference movie (so that no quality is lost and no disk space is taken up), or as a separate, self-contained movie file. The original movie file is not altered in any way. Only one caveat: A reference movie must have the original available to read data from.
Note: This software may not be compatible with all Quicktime movies.
