Data Rates for HEVC Testing

A few weeks ago, I ran a survey to determine the average data rate used by video producers when encoding H.264 to 720p and 1080p resolutions. The thought was, once I knew this, I could encode using HEVC at the half the data rate and compare the quality to see if HEVC lived up to its “same quality at half the data rate of H.264 claim.”

The survey responses are in, and I want to thank all those that participated. Here are the averages and highs/lows.

  720p: Average of 2.9 mbps, ranging from 850 kbps to 5 mpbs.

–  1080p: Average of 4.89 mbps, ranging from 2.75 mbps to 7 mbps.

    Over the next couple of days, I’ll encode comparison files and will include links and my conclusions regarding their comparative quality. Thanks again for those who participated in the survey.
