Generating 'stopwatch' video clips using FFMPEG
I was looking for an easy way to add on-screen timers to a project but couldn't find it. After a lot of stackexchange googling I figured out how to make them using just ffmpeg.
There are three shell scripts for Unix-like systems to create short 'count-up' video clips with 1/10th of second precision at 60fps. Again, you will need to have ffmpeg installed for them to work. The included scripts create 0.0 to 9.9 seconds, 00.0 to 99.9 seconds, and 00:00.0 to 99:59.9 minute clips.
What they look like:

100 minutes https://youtu.be/9g_PiYHDWH4

I had issues with other monospace fonts bouncing when drawing some glyphs. If anyone knows a fix for this I would appreciate it.
