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 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...
