FW: [Mp4-tech] Help on PSNR

[Rob Koenen (MPEGIF)]

The simple answer is that MPEG-4 does not define (acceptable) PSNR ranges,
it just defines a bitstream snytax and a decoding process.
The quality you get depends on many factors, including source material,
encoder quality and encoder settings. 
Best,
Rob
