How to set codec for Quicktime 7 export with AppleScript

Question

Hello everyone,
I'm new to applescript and I'm having some trouble with a batch export of video files.
I'm trying to transcode several image sequences into .mov using QT 7, via Automator.
I found this code that works:
on run {input, parameters}
          repeat with theFolder in input
                    tell application "Finder" to set theSequence to first item of folder theFolder as alias
                    tell application "QuickTime Player 7"
  activate
  open image sequence theSequence frames per second 24
                              set nameSequence to (theSequence as string) & ".mov"
                              tell document 1
                                        with timeout of 500 seconds
  save self contained in nameSequence with replacing
                                        end timeout
                              end tell
                    end tell
          end repeat
end run
The problem is that QT automatically sets the output codec as Photo - JPEG, but in this case I need Prores 422. Is it possible to set a different codec?
One other question: I'd like to set a name pattern for the file name. Right now, it picks the name of the image sequence (imag_seq_001.jpg.mov), but i would like to keep only the first part of the name (imag_seq.mov). And i'd need to do this for different sequences (imag_seq_002, 003, ...), using the same script. Is this feasible?
Thank you for your help.

I have a similar question as well. I tried this for you and nothing happened.

I think "completed file transfer" is regarding to the file being transfered to Apple's Server from your computer when a file is sent, but I'm not sure about "received file transfer invitation." Regarding it being an inline file, maybe try using the attachment class.
attachment n [inh. rich text] : Represents an inline text attachment. This class is used mainly for make commands.
elements
contained by rich text, characters, paragraphs, words, attribute runs.
properties
file (file, r/o) : The path to the file for the attachment  syn file name
