First frame of our input movie:

Add timestamp clock to video

ffmpeg -i input.mov -vf "drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf:expansion=normal: text='%{pts \\: hms}': fontcolor=white:fontsize=48: x=(w-text_w)/2: y=h-th-10: box=1: boxcolor=black: boxborderw=5: line_spacing=32" -vcodec libx264 -vb 2600k -strict -2 -preset slower -f mp4 -an timestamp_clock.mp4
