Please first of all take a look at the video( video link: https://drive.google.com/open?id=1HkW14_BLwse4yQlCsUikZUwLcV9uJYb5 ). As you can see, every time I change from a certain moment to another moment of the video in sony vegas pro 13, I have to wait minimum a second. Sometime it goes fast without waiting time but it happens barely. I also show you my task manager, in this way you can see that my cpu goes really high at the moment I change from a certain moment to another moment of the video. Please help me as it annoys me that I have to wait every time I do this.
