Study: Video Content Trumps Image Quality

HOUSTON, Aug. 12 (UPI) — U.S. researchers say when watching a video, if you like what you see you’re less likely to notice the video quality in the TV show, YouTube video or movie clip.

Rice University psychologists showed study subjects 180 movie clips of varying video quality from grainy and pixilated up to DVD quality, then asked about the video quality of the clips and the desirability of the content, a university release said Thursday.

What the researchers found, they say, was a correlation between the desirability of movie content and subjective ratings of video quality.

“At first we were really surprised by the data,” Professor Philip Kortum said. “We were seeing that low-quality movies were being rated higher in quality than some of the high-quality videos.”

“But after we started analyzing the data, we determined what was driving this was the actual desirability of the content.”

The findings run counter to the popular belief that Americans insist on the best video quality all the time, the researchers said.

“If you’re at home watching and enjoying a movie, we found that you’re probably not going to notice or even concern yourself with how many pixels the video is or if the data is being compressed,” Kortum said.
