Partial answer to my own question, from here: https://superuser.com/questions/717103/burn-filenames-of-single-images-into-ffmpeg-output-video So this command works: ffmpeg -f image2 -export_path_metadata 1 -pattern_type glob -i '*.jpg' -vf "drawtext=text='%{metadata\:lavf.image2dec.source_basename\:NA}': fontfile=/System/Library/Fonts/Helvetica.ttc:fontcolor=white: fontsize=48: x=(w-text_w)*0.01: y=(h-text_h)*0.98" -y CombLapseWithFilenames.mp4 and creates: https://www.kan.org/download/CombLapseWithFilenames.mp4 But the drawtext is the original filenames, e.g. 2024-04-21-08-20-11.jpg, which format I chose in my photo-taking script so that they’d sort properly. Can I reformat that in U.S.-style, e.g. "04/21/24, 08:20:11” and strip the .jpg extension, and do this all in one pass?
