Exporting Still Frames as Pictures
You can export a single frame from a clip in Final Cut Pro, to use as a picture on a Web site.
To do this, select a clip in the Browser or the Timeline to display it in the Viewer, and then move the playhead to the single frame you want to export.
In the menu at the top select:
File...Export...Using QuickTime Conversion
In box that appears, change the Format setting to Still Image.
Click on the Options button and select a format for the picture, such as JPEG, and click on OK.
Now pick a destination folder where you want to store the picture, rename the picture, and click on Save.
The photo will be saved into the folder you selected.
Create a single frame to put in your Timeline
You similarly can create a "freeze frame" for the Timeline that will display as a still image that lasts for several seconds in your movie.
To do this, select a clip in the Browser or the Timeline to display it in the Viewer, and then move the playhead to the single frame you want for your movie.
In the menu at the top, select:
Modify...Make Freeze Frame
Click on the frame in the Viewer and drag it to the point you want it to appear in the Timeline.
You then can grab the edge of the single-frame image to shorten or lengthen the duration of the image in your movie.
