Dive into the powerful video clip properties in ScreenFlow, and learn how to precisely control the look of your clips.
- [Instructor] In this chapter, we're going to dive into ways that you can enhance your story by apply effects to your audio and video clips. If you're following along in the video effects project, effects and ScreenFlow are applied to an entire clip or to an action that allows you to change your effects parameters over time. You apply effects by first selecting a clip either in your timeline or your canvas, and then adjusting the parameters in the properties panel here on the right. The first panel is called the video panel, and it controls the look of the selected clip.
Many of these parameters are tied directly to the clip's canvas controls allowing you to easily make adjustments to the clips scale in the canvas or use the slider or type in a specific value here. The position fields use a standard X-Y coordinate grid that originates at the center of the canvas as 00. The x-value is the first field and the y-value is the second field. Both are measured in pixels and they represent the location of the center of the selected clip.
If you drag this clip to the upper right, then both numbers become positive. To the lower right, the x-value remains positive and the y-value becomes negative. The lower left, both are negative. And the upper left, the x is negative and the y is positive. This allows you precise control over the position of every element on your canvas. The xy and z rotation fields allow you to rotate around a particular axis of your clip. You can either type in a value here, or you can use the rotation selector to dial in the effect.
A good trick for using these rotation dials is to click on the dial and then drag out and away from the rotation dial. Then make your fine tune adjustments by dragging further away you give yourself more control over the value increments. The opacity slider changes the overall transparency of the clip. If you twirl down the cropping section, you can trim the left, right, top, and bottom of you clip using the sliders.
The sliders allow you to trim up to 400 pixels but you can type in a value that's larger than 400. Or you could hold down the Control key and enter the Quick Crop mode to make your rough cropping and then refine it by typing in specific values here. I'll reset all of these back to zero. The Reflection checkbox will add a semitransparent reflection under the clip and the slider adjusts the opacity of that reflection.
The corner round slider will add a radius to the corners of the clip and any reflections that have been added. The Drop Shadow checkbox will add a drop shadow projected out at the angle and the color specified. You can control the look of the drop shadow by changing the Offset to make the clip appear to float higher or lower from the background. And adjust the quality of the light creating the shadow by adjusting the opacity and the blur size.
The Color Controls give you basic adjustments to the color saturation, brightness, and contrast. You can change any of these properties over time by adding a video action. And we'll do that in the next movie.
