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used implementations from the second quarter of 2008 – it shows x264 scoring higher than Dirac – it is now somewhat out of date, and is in any case of questionable scientific merit.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:
“So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.”
—Melinda M. Marshall (20th century)
“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)
“The audience is the most revered member of the theater. Without an audience there is no theater. Every technique learned by the actor, every curtain, every flat on the stage, every careful analysis by the director, every coordinated scene, is for the enjoyment of the audience. They are our guests, our evaluators, and the last spoke in the wheel which can then begin to roll. They make the performance meaningful.”
—Viola Spolin (b. 1911)
