Step 1: Get started
Navigate to the Project Library and open your project in the Timeline. Can’t see the Project Library? Click the Window menu and Show Project Library.
Step 2: Find a frame
Click the Playhead and drag it along the Timeline to locate the frame that you’d like to freeze. Use the Viewer as a guide to finding the right clip.
Step 3: Freeze the frame
Select the Edit menu and choose Add Freeze Frame from the drop-down. The freeze frame will be made and placed on the Timeline, next to the Playhead.
Step 4: Choose the length
By default, the length of the freeze is four seconds. To change this, click Final Cut Pro X and choose Preferences. Click the Editing icon.
Step 5: Change the time
Next to Still Images, click on the up and down arrows to increase or decrease the default length of time for your freeze frame. Close the Preferences window.
Step 6: Freeze an event
You can create a freeze frame using a clip which isn’t in your project. To do this, navigate to the Event Browser and find the clip you’d like to use.
Step 7: Find another frame
Move the Playhead to the part of the clip that you’d like to freeze frame. Use the Viewer to guide you. Once you’ve found it, single-click to mark the place.
Step 8: Stop the action
Next, choose the Edit menu and select Connect Freeze Frame. This will create the freeze frame, but as a connected clip above the main storyline of clips.
Step 9: Add to Event Browser
To add the freeze frame to the Event Browser, add a Marker by selecting the frame and pressing the ‘M’ key. Double-click the Marker and add a label.
