I find shlex.split to be most useful to make my arguments a list in these
cases.

Thank you for your reply. I tried something like this in python code:
from subprocess import call
call(["ffmpeg -framerate 4/1 -start_number 1 -i
C:\\Projects\\data2\\img_%05d.png -c:v libx264 -r 30 -pix_fmt yuv420p
C:\\Projects\\data2\\movie.mp4"])
But it did not work. I get FileNotFoundError: [WinError 2] The system
cannot find the file specified..
You have to pass the command-line arguments as separate items in the list:
call(["ffmpeg",
"-framerate", "4/1",
"-start_number", "1",
"-i", "C:\\Projects\\data2\\img_%05d.png",
... # and so on
])
You should also give it the full path of ffmpeg.
On the other hand, in-loop solution would be more preferable since it lets
me to use variable names of the images and paths..

Why not use the split() method on the string of the command line.
