Quality is normal SD / DVD quality, a bit soft but with decent color. I’ve matched the colors and contrast of the extended Naboo arrival, dissolving from the deleted to the theatrical footage and it works well.
I agree that some effects are too rough, like on the Jedi archive. But the essential ones (senate, padme’s house) are decent. Anything that centers AOTC around Padmé will do, since she’s the main character.
