Adjusting video properties

“

- [Instructor] In this chapter, we're gonna dive into ways that you can enhance your story by applying effects to your audio and video clips. If you're following along, I'm in the video effects project. Now effects and screen flow are applied either to an entire clip, or to an action that allows you to change the effect parameters over time. You apply effects by first selecting a clip either in your timeline or on the canvas, and then adjusting parameters in the property panels on the right. This first panel is called the video panel, and it controls the look of the selected clip. Now many of these parameters are directly linked to the canvas clip controls, allowing you to easily make adjustments to our clips on the canvas, or use the sliders, or type in specific values. There's one click buttons for scale to fit, stretch to fit, and reset the scale. The position field use a standard XY coordinate grid that originates at the center of your canvas as 0-0. The X value is the first field, and the Y value is the second field. Both are measured in pixels and represent the location of the center of your clip on the canvas. Now if you drag your clip to the upper right then both of the numbers become positive. To the lower right, the X value remains positive and the Y becomes negative. The lower left, both are negative, and in the upper left, the X is negative and the Y is positive. This allows you to precisely control the position of elements on your canvas. The XY and Z rotation fields allow you to rotate around a particular axis of your clip center point. You can either type in a value into one of the fields, or use the rotation selector to dial in the effect. Now a good trick for using these rotation dials is to click and drag out and away from the dial before you being rotating. That'll give you more precise control over the actual rotation. The opacity slider changes the overall transparency of your clip. If you twirl down the cropping section, you can trim the left, right, top and bottom of your clip, and each of these sliders will allow you to trim up to 400 pixels, but you can type a value into the field to crop even further, or hold down the control key on your keyboard to enter the quick crop mode, and adjust your crop manually. I'll reset each of these parameters back to zero. The reflection checkbox will add a semitransparent reflection under your clip and the slider adjust the opacity of the reflection. The corner round slider will add a radius to the corners of your clip and any reflections that have been added. The drop shadow checkbox will add a drop shadow projected out at an angle and color specified, twirling open this menu gives you even more control over the look of your drop shadow. The color controls give you basic adjustments to the color saturation, brightness, and contrast. Now you can change any of these properties over time by adding a video action, and we'll do that in the next movie.
