Body: <p>I want to use some kind of effect, to make the video flash for a short time, when something happens. (Example for a gaming video, when you get a kill the screen should flash for like a half a second)</p>
  
  <p>I am using Hitfilm 3 Express. So far i found an effect, which looks pretty good, but i have no idea how to make it look a little more smooth. Is there a way to use effects over time in Hitfilm 3 Express?</p>
