Yesterday I watched Blackmagic Design’s live broadcast, which included many new exciting products. As has been customary for many years, the presenter was Grant Petty, Blackmagic Design’s CEO. I’ll likely cover some of those new products in upcoming articles or reviews. However, one of Grant’s compelling message actually made me think that he may have been channelling the now deceased US-American comedian Rodney Dangerfield (born Jacob Rodney Cohen; November 22, 1921 – October 5, 2004), whose tagline was “No respect!”. This portion of Grant’s message was all about how we should properly handle classic, standard-definition analog NTSC/PAL interlaced footage when digitizing it. You may recall that NTSC had a field rate of ≈59.94 fields per second (since 1953) while PAL had exactly 50 fields per second. Those ≈59.94 NTSC fields were “knitted” together to become ≈29.97 frames per second, while those 50 PAL fields per second were “knitted” together to become 25 frames per second. (However, PAL had two advantages over NTSC: color purity and 100 additional lines of resolution.) In summary, interlaced video was (and is) a technique for doubling the perceived framerate of a video without consuming extra bandwidth. Most of our modern displays are progressive, without fields, so at some point we must de-interlace the original footage into progressive video. Grant (and others) have recently stated that we have been doing that the wrong way. Ahead I’ll cover that in more detail, and how it relates to Grant’s message.
