It is impossible to export your XDCAM (EX, HD…) project with Adobe Premiere Pro CS4. That means you cannot save your XDCAM work in XDCAM with Premiere. To export XDCAM project with Premiere, you have to buy Mainconcept MPEG PRO HD 4 plug-in, whose price is 359 $ (plus appl. Tax).
This situation is not properly indicated by Adobe, that’s the least that one can say. It wouldn’t be false to say it is even hidden.
If anybody knows how to export XDCAM on Premiere Pro CS4 without buying Mainconcept plug-in, let us know ! (But I do not think it is possible.)
Many others professionnals video editing software, which can be less expensive than Premiere Pro CS4, like Final Cut Studio, Sony Vegas and Canopus Edius, can indeed fully manage XDCAM without paying anything more.
