OK, I added "-ascent” to the y coordinate and that fixed the text juddering. Here is the final filter: drawtext=fontsize=60:fontcolor=white:text='%{eif\:(n+0)/16\:d}+%{eif\:mod((n+0),16)\:d\:02d}':x=200:y=75-ascent _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
