To import your new Light leaks for FCPX, simply select FILE> IMPORT> MEDIA or use the keyboard shortcut ⌘I and choose the light leak files in the browser pop-up window. Also, you can click on the media import button shown here.
# Select the Light Leak You Wise to Use
Just treat your new light leaks like any other footage in Final Cut Pro X. Examine the light leak until you detect the part that you think will work best. Set the entry and exit points around the part of the light leak that you wish to use. See more!
# Place the Chosen Light Leak in the Layer Above the Existing Images
If your original footage is in V1, then you must place the light leak clip in V2, directly above the footage you want to influence in Final Cut Pro X.
# Alter Composite Mode of Light Leakage
To do this, first click on the light leak layer in the sequence to choose that layer. Open the inspector window by clicking on this button on the far right of the Final Cut Pro X design. Then, in the inspector window, search for “Compositing” and click “show.” In the Merge Mode drop-down menu, choose the composite mode you want to use.
# Experiment, Experiment, Experiment
Now you know that how to apply a light leak to your footage, you can take time to adjust and experiment to get the exact look you are looking for. Here are a few things you can do to help create an individual look.
* Modify Color
Playing with the color of the light leak clip will let you alter the light leak from warm to cold and from saturated to monotonous.
Accelerating light leaks can provide a frantic feeling to your footage: this works well for action sports footage like motocross or skateboarding. Decreasing the speed of a light leak can help make a relaxed atmosphere.
* Flip Flops
Do you want the light leak to come from the left of the frame, not to the right? That’s simple, just throw the shot!
* Use Many Light Leaks Immediately
Using more than a light leak can actually help define the tone you are looking for. For a truly unique look, use light leaks from various collections.
Technically, there is another “level” that can be used within the so-called Theme categories, but unless you feel comfortable installing the effects in the “usual” method, you should not worry about it. Check out this site: https://en.wikipedia.org/wiki/Light_leak
