Performance
The algorithms in the Dirac specification have been designed with the intention to provide a competitive performance as compared to state-of-the-art international standards. Whether they succeeded is an open question; while at least one comparison exists which used implementations from the second quarter of 2008 – it shows x264 scoring higher than Dirac – it is now somewhat out of date, and is in any case of questionable scientific merit. A study on the performances of the Dirac codec, dated from August 2009, finds that the quality obtained on SDTV is inferior to the H.264 output. The study mentions HD in its conclusion, but the numbers on HD are conspicuously missing.

Famous quotes containing the word performance:
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
—Henry David Thoreau (1817–1862)
“There are people who think that wrestling is an ignoble sport. Wrestling is not sport, it is a spectacle, and it is no more ignoble to attend a wrestled performance of suffering than a performance of the sorrows of Arnolphe or Andromaque.”
—Roland Barthes (1915–1980)
“Having an identity at work separate from an identity at home means that the work role can help absorb some of the emotional shock of domestic distress. Even a mediocre performance at the office can help a person repair self-esteem damaged in domestic battles.”
—Faye J. Crosby (20th century)
