Firstly I truly appreciate all of your responses and the time you took to research them.
I take it there is no documentation available for the quicktime implementation of the JPEG 2000 codec? I could not find any either.
The specific answers I need in written documentation for a government report are this:
Is the JPEG 2000 implementation in quicktime consistent with the Motion JPEG 2000 (often referenced as MJ2 or MJP2)? It is an open ISO standard and does not employ temporal or inter-frame compression. Each frame is an independent entity encoded by either a lossy or lossless variant of JPEG 2000.
As highlighted earlier I am specifically interested in LOSSLESS compression.
Thanks again for your responses David, Klaus and Kirk but:
David your statement "I would say since the codec uses the name jpeg that it's lossy." is mostly true but this isn't always the case, please see below. Again I am looking for where the documentation is located, so I can PROVE what you are saying is correct or not.
Klaus I disagree with your statement "No jpeg compression is lossless" and one of the reference links you gave "http://en.wikipedia.org/wiki/JPEG_2000" also contradicts that statement. That is unless you specifically mean the Quicktime implementation and not jpeg in general. This is exactly the information I am trying to discern but I need documentation to substantiate it.
Kirk "Any export could introduce additional compression of your source format." This is true but not so if I export uncompressed video as uncompressed video for example. If you can point to where the documentation says the Quicktime implementation of "JPEG 2000 is an "image" format (not a video compression codec)" I would love to see it, otherwise it is just an opinion - albeit a good and very likely correct one!!!
Being a mac fanboy I WANT to employ quicktime JPEG 2000 but unless I can PROVE with documented evidence QT JPEG2000 IS lossless for government archival use, my hands are tied.
An example of a company that does use JPEG2000 lossless today is Samma Systems:

Is there written documentation that Apple's implementation of JPEG2000 is mathematically lossless or is it only visually lossless?
Apple??? ISO??? Anyone???
