SLow motion in composing shot
I apologize for my english.
I'm a beginner with hitfilm express! I have a problem when I want make a slow motion in a composing shot.
I use the speed effect. When I slow down the vidéo, I lost the end of this one.
Video 10 seconds - Composing Shot 20 seconds. If I slow the video down by 2. After 10 seconds, I saw the half of the vidéo and I have a black screen for the 10 next seconds.
Is it normal ? Else, how to make a smooth transition for a slow motion ?
