Join Chris Mattia for an in-depth discussion in this video Adjusting video properties, part of ScreenFlow Essential Training.
- [Instructor] In this chapter, we're going to dive into some tools and techniques that you can use to enhance your story by applying effects to your audio and video clips. If you're following along, I'm in the Video Effects project. Effects and ScreenFlow are applied either to an entire clip or to an action that allows you to change an effect's parameter over time. You'll apply effects by first selecting the clip either in your timeline or in the canvas, and then adjust the parameters here in the property panels on the right.
This first panel is called the Video panel and it controls the look of the selected clip. Many of these parameters are directly tied to the canvas' clip controls, allowing you to easily make adjustments to the clips either on the canvas or using the sliders or type in specific numerical values here. The position fields use a standard x, y coordinate grid that originates at the center of the canvas as zero, zero.
The x-value is the first field, and the y-value is the second field, and both are measured in pixels and represent the location of the center of the clip. If you drag this clip to the upper right, then both of these numbers become positive. If you move the clip to the lower right, then the x-value remains positive and the y-value becomes negative. The lower left quadrant, both x and y are negative, and the upper left quadrant, the x is negative and the y is positive. This allows you to precisely control the position of elements on your canvas.
The x, y and z rotation fields allow you to rotate the object around a particular axis. You can either type a value into the field here or use the rotation selector to dial in the effect. A good trick for using these rotation dials is to click on the dial and drag out and away from the dial. Then begin rotating your mouse around the dial itself. 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, bottom or top edges of the clip. Each of these sliders allow you to trim up to a maximum of 200 pixels for any one side, but you can type in a value that's higher than 200. You can also hold down the control key on your keyboard and enter the quick crop mode and then make adjustments with your mouse, and then refine those selections here.
I'll reset each of these crops back to zero. The reflection checkbox will add a semi-transparent reflection under the clip and the slider adjusts the opacity of the reflection. The corner round slider will add a radius to the corners of the clips and any reflections that have been added. The shadow checkbox will a drop shadow projected out at the angle and with the color that's selected in these fields.
You can change the offset of the drop shadow to adjust the look of how high the object appears to float above the background using this slider and you can adjust the opacity of the drop shadow using this field and adjust the quality of the light by adjusting the blur size to increase the blurriness. I'll turn the drop shadow off. The color controls give you basic adjustments to the color saturation, overall brightness and contrast for the clip.
You can change any of these properties over time by adding a video action. With the clip selected, place your play head at the place where you want the transition to end. Then click on the add action button here in the upper right corner of the panel. A yellow action bar will appear on the clip. The left side of this bar is your starting keyframe and the right side is the ending keyframe. Since the ending keyframe is already selected, set the video properties for how you want your clip to end up looking over in the properties panel.
Then drag the beginning keyframe of the action back to the point in time where you want the transition to begin taking place. Then park your play head at the starting keyframe and adjust the incoming parameters. A quick way to restore your clip settings back to default is to click the gear icon in the upper right and select reset to defaults. Then back up your play head and preview your animation.
ScreenFlow will build the animation for you. If you want to slow down the animation, drag the starting and ending keyframes further apart. If you want to speed up the animation, drag these keyframes closer together. You can also drag an action horizontally along the clip to change the position in time that the action will take place. Finally, if you select an action and copy it to your clipboard, then move your play head down to another location in the same clip or to a different clip and then paste, you can paste a second copy of the action so that you don't have to repeat it.
A great way to make an animation look like it's coming in and then going out is move down to the ending keyframe and then with the action selected, go back up to your gear icon and reset to defaults. I'll drag these two actions closer together so we can see the overall effect if I back up my play head and preview it.
