For some time I’ve been promising people a copy of the FCP project file I used to create a countdown. I found it and here it is: FCP (right-click or control-click to save). BTW, it’s in FCP3 format, so it should be editable in versions 3 and later. Additionally, this isn’t a video file, but a project file. Don’t expect it to play if you don’t have Final Cut.

Notice that I used nested sequences to minimize the work needed to create this countdown as I did each number by hand, not merely reversing timecode as I had in the past.
