Editorial: High Frame Rate (HFR) Movies and the Choice of Frames per Second

EditorialHigh Frame Rate (HFR) seems to be the new buzzword in movie production, these days, at least to some directors who are experimenting with it. For example, The Hobbit was shot at 48 FPS (Frames per Second), with a 4K digital video camera. The idea is that HFR makes motion much smoother. And it works. But, do we, as viewers, then feel that we are actually in the scene, as opposed to being in the audience? One industry professional who is working with 4K and 3D said he hated the 48 FPS. It takes away the "film look" that so many people like, and turns the motion picture into something that has the "Soap Opera Effect", namely, live TV. But, notwithstanding the visual effect, let's focus on the choice of 48 FPS and why this is a potential disaster.


Editorial: The Industry Learns a Lesson: The Death of 3D vs. Industry Predictions. Will this Change their Plans for Introducing 4K to the Public?

EditorialThe recent announcement that ESPN is eliminating its 3D channel on cable and satellite tells a sad story of overestimating the impact of 3D on selling more HDTVs. Although 3D movies continue to be released - for the time being - it appears that consumers are not interested in watching 3D at home. The "glasses" are claimed to be the scapegoat, but I think there is more to it than that.

But exactly how does an LCD TV work?

TVs? We don't need no Stinking TVs - Third-Generation Multichannel Audio - Part 3

It is useful to have the Blu-ray player read downloaded MP3, FLAC, and WAV files off a memory stick. If the player is well designed, the MP3 files should display information on the work and the performer on the TV screen. FLAC files encoded at sampling rates of 96kHz, or a sampling rate or 192kHz, should be bit-accurate at the both the S/PDIF or HDMI outputs. Be careful; many Blu-ray players do not support FLAC data files.

Most Blu-ray players USB ports will also work with Hard Drives. Another option on many Blu-ray players is to find music across a computer network if you establish an Ethernet connection for the Blu-ray player to your computer router. Special software must be resident on the computers. How to do this is way out of the scope of this article.

It is most important that your Blu-ray player should read MP3, FLAC or WAV files that are burned to DVD on a computer.......
