Need help very badly!
I aligned many clips in the timeline,
selected one of them and changed speed.
Since then the Clip doesn't show up in the viewer!
Everytime the (how do I call that? white time-pointer that travels through the media when playing the whole thing) passes this one clip I am getting an empty screen (the one with the tile-pattern!)
(Can't add a screenshot, since no uploader seems to work in this Forum?) !
