Macintosh and DOS file name conventions are different. This can create problems in cross-referencing among movies after the movies are transferred from one platform to the other. This was dealt with by using eight character file names only. Macintosh and windows fonts may differ. Under windows, transitions may not occur at the same speed as on the Macintosh.
Pixel dissolves are coarser under windows.
Certain transitions were avoided because of this. Macintosh and Windows platforms utilise different native sound formats. If a program other than Director is used the author's software must support the particular sound format he or she is using on both platforms.
