thank you so much, I am going to try it now! I am on a mac. Do you know if this is an XML formatted file? What I found was a User_Settings.xml file. I can’t seem to find anything else on my system, even hidden files, that would give me more access then what I am seeing in this XML, but I am not able to find any demsnion presets that I would be able to add a line item to. I have a feeling I am in the wrong file as the content is specific to the content of the file I am working on and not so much the system, though it has a lot of presets for the system as well, like file types supported, and window locations etc. Thoughts? Thanks again for the help here!
for anyone else on a Mac wondering where the file I am working with is located:
Documents/Adobe/Speedgrade/6.0/Settings/User_Settings.xml
