MotioneyeOs

Convert files in chronological order

Glue files together to an animated gif:

• by renaming them in chronological order (using linux command)
• by using ffmpeg to convert into a movie and animated gif

ls | cat -n | while read n f; do mv "$f" `printf "%04d.jpg" $n`; done
ffmpeg -r 3 -f image2 -start_number 1 -i %04d.jpg -codec:v prores -profile:v 2 output.mov
ffmpeg -i output.mov -filter_complex "[0:v] fps=12,scale=800:-1" schaduw.gif
