add leading zeros to *.png

[ibaaj]

if you use :

ffmpeg -i ./directory/out-%d.png video.mp4

ffmpeg will create a video from frames in the same order as when you do a ls:

out-1.png
out-10.png
out-11.png
out-12.png
out-13.png
out-14.png
out-15.png
out-16.png
out-17.png
out-18.png
out-19.png
out-2.png
out-20.png
out-21.png
out-22.png
out-23.png
out-24.png
out-25.png
out-26.png
out-27.png
out-28.png
out-29.png
out-3.png
out-30.png

For a correct video, you need to add leading zeros to filenames.

It always worked for me. But I have solved it by adding a number format option to the stylizing script itself.
