If you export a still image from the end of a Final Cut Pro sequence, it's possible for the result to be a blank white image, instead of the sequence's last frame.
Before you export the still, be sure that the playhead position is at the beginning of the last frame, instead of after the last frame.
In normal editing, this might be hard to see, but the following illustrations show the end of a sequence as seen at a high zoom-level in the Timeline. Note the difference in the location of the playhead in the illustrations.
The playhead in the correct position for exporting the last frame as a still image
The playhead in the wrong position for exporting the last frame as a still image
Follow these steps to reliably export the last frame as a still.
