Automator copy only certain file extensions

Question

Hi,
This should be so simple. I have tried using automater to search and filter ONLY .mp4 and .mov file extensions in a certain folder and copy it to another folder. Automator seems to work fine copying from folder to folder but copies all files to the new folder.
For the life of me, I can't seem to get the correct script/workflow working. This should be so simple.
Could someone please clue me in on how to do this? I would truly appreciate it!
Matt

You need to test if the file exists:
tell application "Finder"
          set theList to (every file of folder "Documents:_RENDER FARM" of home whose name extension is in {"mov", "mp4"})
          repeat with theFile in theList
                    set fileName to do shell script "basename " & quoted form of POSIX path of (theFile as string)
                    set x to ((folder "Documents:Google Drive:Cinema 4d:_from render farm" of home as string) & fileName)
                    if not (exists x) then
                              copy theFile to folder "Documents:Google Drive:Cinema 4d:_from render farm" of home
                    end if
          end repeat
end tell
