 1. Put this text into a file "filter.txt":

 {{{
 drawtext=text='%{pts\:hms}':fontsize=128:fontcolor=white
 }}}
 2. Execute

 {{{
 ffmpeg.exe -i trembling_text_input.mp4 -/filter:v filter.txt
 trembling_text_output.mp4"
 }}}
 3. Open the newly created file, "trembling_text_output.mp4", in a video
 player. Notice that the timestamp text is trembling.
