Typical old movie countdown. Counts from 10 to 2 (1 is there if you want to add it). 24fps. If you want to change the framerate, you will need to adjust the timings of the number appearance/disappearance and the keyframing of the sweep shapekey.
There are three empties just outside the frame (camera is in orthographic mode). By scaling these empties, you can adjust how much the elements "jitter" around in the frame to simulate an old style optical printer with none too good registration. The crosshair, the circular surround, and the numbers are all on path constraints to some very small random paths with 120 points each. Scaling the empty scales the path. The numbers aren't tied directly to the path because weird things happen. So the numbers copy the location of an empty on the path with a location constraint.
The grain in the video was created in Gimp and added in the sequence editor. It is not part of the .blend file.

Thanks for your video. it's exactly what I need. I'm also learning video editing with my location.
Nice job, that looks really good:)
