BBC: Ultra-HD May Need More Than 120 FPS reports that BBC technology guru Andy Quested says that Ultra-HDTV will need much higher frame rates than today’s 24/25 frames/second or 50/60 fps, depending on content. Quested, speaking to 3D Focus says that so-called ‘image smearing’ was a risk for 4K and 8K Ultra-HDTV transmissions.

“At 50/60 [fps] though, the increased temporal resolution accentuates the smearing caused by movement when the shutter is open, but make the shutter too short and the low frame rate causes multiple images during some motion (look at what looks like a multi-arm bowler in short shutter cricket).  At somewhere around 100+ fps your eyes cease to see separate images even during high movement with short shutter.  More testing is needed to know what works and what doesn’t,” says Quested, whose official title is Chief Technologist HD & 3D at BBC Technology.
