Below two commands would create a GIF file from the same above set of image files.
ffmpeg -start_number 1 -i '%d.png' -c:v libx264 out.mp4 ffmpeg -i out.mp4 -pix_fmt rgb24 -loop 0 out.gif
- -start_number = indicates from which file number present in input image file name it would start creating the gif.
- -i = the input files, %d denotes any number present in image files.
- Libbx264 = The output video codec
