In this paper, a simple mathematical formula is proposed which provides estimation for the perceived video quality, based solely in the codec used, the display format, the bit rate and the movement content in the original video. The quality metric used is one of the recently standardized in Recommendations ITU-T J.144 and ITU-R BT.1683, and developed by NTIA. The error obtained with the proposed formula, regarding to the ITU models, is between the ITU algorithms error margins, according to the subjective tests developed by the VQEG. Studies were made for more than 1500 processed video clips, coded in MPEG-2 and H.264/AVC, in bit rate ranges from 50 kb/s to 12 Mb/s, in SD, VGA, CIF and QCIF display formats.
