then your cms is broken by design

been there, done that, doing it as daily business
it's easy to submit task-lists and file-uploads which are
proceeded by cron-scripts without open security leaks
on the webserver

this idea is broken by design
even if it would work basically you will run in timeouts
on the webserver if the ffmpeg-process takes longer

this issue has clearly nothing to do with ffmpeg

ask the support of Hostgator
ask in specific mailing-lists for PHP on windows

if this is a shared-server and shell_exec() would work
the admin of your hoster should be fired as the one
from a linux machine which allows shell_exec fro httpd

any sane php-setup for a webserver has this config:
disable_functions "popen, pclose, exec, passthru, shell_exec, system, proc_open, proc_close, proc_nice,
proc_terminate, proc_get_status, pcntl_exec, apache_child_terminate, posix_kill, posix_mkfifo, posix_setpgid,
posix_setsid, posix_setuid, mail, symlink, link"
