Most people are aware that the amount of detail in a photograph is dependent on a few things. Assuming focus is right, it’s easy to assume it’s a combination of how well the lens was made and the number of pixels on the sensor, give or take the quality of all those things. Now we’re starting to hit issues with what we might almost think of as the size of light.
SDI and IP differ fundamentally in their approach to data transport as SDI is circuit switched and IP is packet switched. This provides interesting challenges for us as we start to consider what it means to route IP signals.
Our first Essential Insights is a set of three video episodes in which we discuss transitioning to IP with industry experts. We explore the fundamental challenges during the planning stage. The decisions that need to be made, and the long-term thinking needed to maintain flexibility, scalability and resilience.
The best sampling rate for digital audio is easily established by considering the requirements of the human auditory system (HAS), which is the only meaningful arbiter. Provided that the bandwidth of a digital audio system somewhat exceeds the bandwidth of the HAS, that should be enough.

Some films languish in preproduction hell for years. For cinematographer Simon Rowling, though, only a matter of days elapsed between first discussing Legacy of Lies and flying out to begin location scouting. The production, which stars Scott Adkins as a CIA agent in pursuit of Russian kidnappers, was written and directed by Adrian Bol and photographed mainly in Ukraine.
There are many different requirements and expectations in the field of computer security and it may be as well to set out what some of them are. Computation is everywhere, from the ubiquitous iPhone to the military computer in an underground installation, and it is unrealistic to think that one security approach would suit all requirements. Computer security is also awash with buzzwords and these will crop up here with definitions of what they might mean.
With the recent advances in artificial intelligence, post-production rotoscope tools are now so good that some DOPs are asking if we still need to use green screen at all, or at least, in quite the same way. Suddenly, it seems any background, no matter how complex, can be replaced in seconds on the editor’s timeline, allowing DOPs to shoot complex compositing assignments faster and more economically. For broadcasters, the benefits of an AI-powered rotoscoping tool are substantial as producers can repurpose a treasure trove of existing footage packed away in libraries and potentially reduce the need for new production or costly reshoots.
Television production these days is tricky enough without adding virtual elements like augmented reality (AR) graphics, but that’s exactly what Taipei-based production company Getop did for the live telecast of the 2020 Golden Melody Awards (GMA). The highly rated annual televised awards ceremony - considered the “Asian Grammys” by many - celebrates top musical talent from across southeast Asia.
