So, I fixed the issue!!!!!
Not sure if this is a fix for everyone but here goes:
First I tried to create a new admin user and opened Motion to see if there were other issues at a system level. This changed nothing. Next I went back to my original user and opened (~/library/quicktime) and right clicked on any file within the folder……while right clicking I pressed the option/alt key which changed the contextual menu to display “Show Inspector” instead of “Get Info.” Then select “Show Inspector” and that will pop up the info window. scroll through each file in the quicktime folder and watch for any files that are in the folder that are NOT copyrighted to Apple. Remove the files that are not Apple copyrighten and place then in a folder on your desktop. Now reopen Motion and see if that worked. This fixed my issue as I must have had a quicktime file conflict. Also I had Perian installed in system preferences and I uninstalled it as well. Once I got Motion working again I one by one moved the quicktime files back into the folder and tried Motion to find the culprit file.
Hope this helps!
