Ed's View - The "Film Look"

By Ed Milbourn • Aug 30 2005, 5:30pm

As HDTV becomes increasingly popular as both a production and display medium, the subjective differences between motion picture and video originations become more apparent. This is because HDTV reproduces the image more accurately than SDTV, i.e., by definition HDTV is much more "transparent" than SDTV.

The motion picture film image has significantly different qualities than images produced by video cameras. There is not one specific factor that characterizes the difference, but a litany of them. Interestingly, attempts by engineering texts to quantify and precisely define the "film look" have met with dubious success. This is little agreement as to the exact characteristics defining the film image. It is a "you know it when you see it" thing - very ephemeral. Subjective characterizations such as smooth, muted, and surreal are identified with film as compared to video characterizations such as sharp, harsh and vivid.

And it is (drum roll) -1080p. 1080p is one of those incremental improvements in HDTV to which I have been referring to in my previous articles. 1080p, of course, means 1080 horizontal lines scanned one after the other, or progressively. This is apposed to 1080i that denotes 1080 lines scanned in an interlaced fashion, with the odd number of lines scanned initially and the even number of lines then scanned and positioned, or "interlaced," between the odd lines.

So, is 1080p better than 1080i? Is it better than 720p? The answer to both of these questions is...
