first i tryed to play them directly without converting them.
(my output has the same size as the movies)
this worked fine for movies with fast changing content.
for movies with slow, elegant movements ito it not
so i converted them into quicktime movies with foto jpg compression.
for good results, i had to go to the double framerate to 50 fps. (i am living in a pal country)
these movies were jerking in modul8, without applying any effects in modul8 !!
i played them with the quicktime player through the second monitor out without
problems.
perhaps, somebody has an idea to solve this problem.
perhaps an other codec etc.
my system is: mbp, 2,16ghz intel core 2 duo, 2gb ram
all the best from the videomasta !
