I am making an animated GIF file using following command:
convert -delay 10 -loop 0 *.png animated.gif
But, the problem happens in the order of *.png.
My PNG files are like 1.png, 2.png, ... 100.png.
In the resulting animated GIF, the order of frames are like: 1.png, 10. png, 100.png, 2.png ...
I want that in the resultant GIF the snapshot are in order like 1,2,3 ... 100.
Please try sort:
$ ls | sort -V
1.png
2.png
10.png
100.png
So ultimately:
convert -delay 10 -loop 0 $(ls *.png | sort -V) animated.gif
This little script will rename your files for you with leading zeroes - try it on a COPY of your files first:
#!/bin/bash
for i in {1..1000}; do
[ -f "$i.jpg" ] && echo mv "$i.jpg" $(printf "%04d.jpg" $i)
done
It looks for JPEG files from 1.jpg through 1000.jpg and if any exist, it renames then with up to 3 leading zeroes till the number part is 4 digits wide.
If you save it as renamer, you will then run
chmod +x renamer # just do this once to make it executable
./renamer # do this any time you want the whole directory of JPEGs renamed
Remove the word echo if you see and like what it is going to do, then run it again.
Sample output
mv 1.jpg 0001.jpg
mv 99.jpg 0099.jpg
mv 102.jpg 0102.jpg
Rename your images with leading zeroes like:
001.png, 002.png, 003.png,......099.png,100.png.
And it will work fine for you
The glob operator (*) sorts the result list by comparing texts. So renaming the files 1.png, 2.png ... to 001.png, 002.png should work.
