Ex uno plures

There were many wonders at the 17th-annual HPA Tech Retreat in February in the California desert. And many of the more-than-500 attendees at the Hollywood Post Alliance were left wondering. One thing they wondered about was how to accommodate all viewers from a single master or feed. As usual, many manufacturers introduced new products at […]  More

Headphones, History, & Hysteria

Headphones are an integral part of modern media production and distribution. So, who invented them? Here’s one theory: “The first stereo headphones were invented in 1958 by John C. Koss….” That statement may be found at this web site: http://www.bookrags.com/research/headphones-woi/ Here’s another: “[The Beyerdynamic] DT48 was designed in 1937, the first pair of headphones in […]  More

3D and Not 3D: The Knowledge Returns

Last year was a wonderful one for 3D.  In terms of worldwide and domestic box-office grosses, six of the top-10 movies released in 2010 were in 3D. And by year’s end there were almost two dozen models of integrated 3D cameras and camcorders and literally dozens of models of two-camera 3D rigs. There’s just one […]  More

When Did We Come From?

  NPR’s On the Media has been my favorite news show. They explain the how and why of media issues, debunk myths, and correct errors — even their own. When it comes to media technology, however — especially its history — they sometimes get things wrong and don’t correct the errors. Examples of those uncorrected […]  More

How Different Is 3D?

When you watch a televised advertisement for an automobile, do you fear there’s a moving car in the room with you? I didn’t think so. But more on that later. This post is about human perception of 3D imagery. It’s also about how we see moving images in general and about color, sound, carsickness, and […]  More

125th Anniversary of Pay Cable

Question: What is shown in the drawing at the left? Here’s more information to help you figure it out: It’s a small portion, the lower left corner, of a larger drawing, and there’s something very similar at the lower right corner as well. The larger drawing appeared as a two-page spread on pages 76 and […]  More

IBC 2010 – 2D, 3D, 4D, 5D

There was plenty of 3D at the International Broadcasting Convention (IBC) in Amsterdam this year.  At the awards ceremony, alone, the audience was frequently asked to don 3D glasses to see clips from the winners (before viewing a portion of the not-yet-released 3D movie Tron: Legacy).  But the first sentence of the first comment posted […]  More

What's Next?

These were some of the things that could be seen at Canon Expo at New York’s Javits Convention Center last week: ice skaters pirouetting without ice, people viewing someone dressed as the Statue of Liberty from the moving deck of a fake boat, a machine that can squirt out a printed-and-bound book on demand, and […]  More

Can You Fix It in Post?

Can you fix it in post? The simple answer is: Yes. Consider Avatar.  Not only was an entire world created and populated in computers, but even a human actor’s legs were atrophied in post.  So, yes, anything can be fixed in post — given enough time and money.  In the worst case, artists would simply […]  More

3DTV Today: One Step Back

The Society of Motion-Picture and Television Engineers (SMPTE) just completed an International Conference on Stereoscopic 3D for Media and Entertainment, what it calls “the only scientific gathering focused exclusively on 3D.”  Like many SMPTE conferences, it gazed into the future, with one presentation introducing “the need for additional image processing to get pixel-level geometry matching,” […]  More
