create a movie with python

[masoud]

To run command line programs from within my script I used subprocess.

First I added import subprocess and then:

subprocess.call("avconv -framerate 1 -i fig%06d.png -c:v libx264 -profile:v high -crf 20".split())

Now, although I can see the saved *.png in my Folder but still I CAN'T create a movie. I don't know what do I have to do to correct the code to create a movie. ANY SUGGESTION???
