Handbrake Conversion

Hey Guys,
I know there have been a few posts about using hazel to watch a folder and use Handbrake to automatically batch a bunch of files to a certain output type on the forum here but I can't find anything that seems to work. I'm not a big coder so any instructions n00b style would be great. Some of the movies I have are ISO's so essentially I want to convert it into an avi or mp4 which I would normally do manually in handbrake.
Thanks
