Subject: executing an AE script from Python 2.7
To: After Effects Mail List <AE-List@media-motion.tv>

I'm trying to execute an AE script from Python and it doesn't appear
that the script argument is passing correctly. I'm using Windows 7
with Python 2.7.

If I use cmd.exe or powershell and try "afterfx -r
D:\pipeline\tests\tactic_ae\hello.jsx" I get my "hello world" alert in
the AE UI.

However, if I try executing in Python:
subprocess.call(["afterfx","-r","D:\pipeline\tests\tactic_ae\hello.jsx"])
The AE UI takes focus but no alert appears. The strange part is if I
try to do something invalid like remove the -r flag:
subprocess.call(["afterfx","D:\pipeline\tests\tactic_ae\hello.jsx"])
I get an AE error: After Error Can't import file "hello.jsx":
unsupported filetype or extension

Anyone know why the alert won't display when run from Python? Thanks!
