“The same codec was used in the attempt to make the QT reference”
if you specify ANY setting, even one that exactly matches your source,
you will get a self-contained file.
the trick is to use the “Same Settings” menu item.
you do realise that handing over a reference file to anyone else is a rather risky situation.
are you giving them the entire drive, so the reference move will have the correct files to refer to?
is there a problem with using your larger self-contained file?
