 Kinescopes have such poor quality that for many years they were thought to be unusable for modern video and television.However, advances in digital technology have made it possible to master "Mayerling" from the original kinescope negative and print materials in high definition, which mysteriously brings out more details than could be seen with the naked eye watching the television broadcast.The master was then upgraded using the latest digital programming — the grainy appearance was softened, blurred edges are put back in focus, brightness/darkness was adjusted, hand-editing replaced numerous frames with a flash of light with a duplicate frame preceding the bad frame, sound was upgraded to remove most static/pops/hisses, and so on.
