Learn how to use automated scrub tools with the ProScrub Lesson.
STEP 1 - Preparing The Timeline
Let’s begin by selecting our footage from the FCPX media library and dragging it to the timeline. To properly use ProScrub you must turn your footage into a compound clip.
You can do this by right clicking on your media and selecting New Compound clip. Then locate ProScrub in the Effects library. ProScrub has 4 different types of presets, Each with various options.
For this example we will cover the Back and Forth Preset that only focuses on the current frame. Click and Drag the preset directly on top of your media. Select your media and go to the inspector window.
STEP 2 - Back & Forth Controls
First you will notice the Instructions which will show up once you drag the preset to your media. Click the instructions check box to hide the ProScrub notes.
Next we will go over the ProScrub Controls. The Frames Affected slider allows you to determine how many frames ProScrub should affect. After setting the frames affected slider move onto the speed slider.
The speed slider can decrease or increase the speed of your media. Move the slider to the left to slow down the effect and move the slider to the right to speed up the effect.
Frame Blending helps to smooth the look of a given effect over the duration of the video clip it is applied to. Now that we have covered each control let’s try out ProScrub.
For this example we will set the Frames Affected slider to 300. Let’s start the speed off slow and leave frame blending off. For the next example we will keep the Frames Affected slider at 300 but this time let’s ramp up the speed and enable the Frame Blending option.
STEP 3 - Custom Speed
ProScrub comes a custom speed preset which allows FCPX users to alter the timing of their video clips. Click and Drag the Custom Speed preset to your media.
Then go the viewer window where you will see a Custom Speed Tool Graph. This Graph is a visual representation for the speed adjustments you will be making.
You have the option of using the controls in the inspector window or you can use the on screen controls in the viewer window. If you ever need a reminder of what the Custom Speed effect does Just click the instructions check box.
You can hide the custom speed graph by selecting the Tool Guide check box so you can see the adjustments you have made. Now let’s continue down to the On - Screen controls.
Adjust the Scale, Rotation and position in the inspector window or use the on screen controls in the viewer window to make those same adjustments. Click and drag the center control puck in the lower left corner of the graph to position it.
Custom Speed Continued
Once your have the Custom Speed Tool graph set up you can begin adjusting the speed of your media. First adjust the Frame Count Slider.
Set the Frame count slider to match the number of frames in your media. Then go on to the Speed Adjustment sliders. The X slider controls the time and the y slider controls the video duration.
You can use the on screen controls to make these same adjustments. Click and drag the control puck located in the middle of the graph. The higher the curve the faster your media will move. And the lower the curve the slower your media will move.
