Generates countdown timer frames which can be overlaid on movies using ffmpeg.

Usage:

1. Figure out how many frames the movie has and what the frame rate is and what the dimensions of the frames are (you can use ffprobe or ffmpeg for this).
2. Enter the data: the main idea is that height is much smaller than the video frame height.
3. Generate the frames. They'll be downloaded in a zip file.
4. Unzip the countdown frames in a directory of your choosing.
5. Overlay the countdown on your video:

$ ffmpeg -i movie.mp4 -r <frame rate> -f image2 -i 'countdown/frame%08d.png' -filter_complex "[0:v][1:v] overlay=0:0" -pix_fmt yuv420p -c:a copy -preset medium -c:v libx264 movie_with_countdown.mp4
