David Newman of CineForm has been conducting some greenscreen testing of their codec vs HDCAM SR (everything shot on a Viper). The results of the informal blind quality poll have been revealed, along with some more in-depth mathematical analysis.

“Here are the stats from the entrants :
25% said the images all looked identical.
25% said the first CineForm clip was uncompressed.
37% said the HDCAM-SR clip was uncompressed.
25% found the uncompressed clip correctly (one user changed his mind after a week and got it correct the second time.)”

“We ran multiple shoot tests with the Viper in Filmstream mode, charts, green-screens and one outdoor sequence. In all tests the CineForm modes out performed the SR deck in most common 440Mb/s mode…”

Read on for some of the PSNR statistics from the outdoor sequence and further explanation.
