# 1. Convert the file to gif using ffmpeg
# - input path argument `-i`
# - pixel format argument `-pix_fmt`
# - removing some frames using framerate argument `-r`
# - end `ffmpeg` with new path/to/filename
# 2. Optimize the same output file with third option -O3 
# and rewrite the generated gif file from last step
# 3. Notes: using && to make sure the conversion sucess before optimizing
