At the top right corner, right above the little preview box, you will have options for cropping, changing saturation, changing the tone, and panning.

You can increase and decrease the saturation, color and tone to your desired level by clicking on the respective icon then dragging along the line that appears next to it.

To crop, you click on the cropping option, then resize the box that appears. This will cut the video to the size of the box. You may change the size of this box.

To pan, click on the pan icon and drag the arrow to where you’d like the video to pan to. When you now play the video, it pans when it gets to that cropped part.
