BTW, all you have to do is watch The Searchers to see this proved out.
| From Videotape Products, Inc. What is the spatial resolution of 35mm Motion Picture film? |
The spatial resolution of the active area of standard 35mm Motion Picture Camera Color Negative was, prior to Kodak's introduction of Vision stock, measured as 80 line pairs per millimeter, or approximately 167 pixels per millimeter in any direction. The horizontal and vertical pixel count depend upon the camera aperture (e.g., there is no increase in horizontal pixel count due to anamorphic lens image compression onto the camera negative). 35mm film negative can easily be rated at as high a resolution as 4096x2987 for Academy Aperture. The "2K" level is considered half resolution of 2048x1493 for Academy Aperture. The visual effects industry has been working at the "2K" level for years, usually with less vertical resolution due to the masked horizontal aspect ratios the filmmakers have chosen of 1.85 or larger (a horizontal rectangle). Because of film to film generation loss, poor projection quality (from such factors as simple as turning up the lamp brightness on the projectors), and forced limited print contrast range of from 6 to 8 stops, the 1920x1080 8 or 10 bit capabilities of high definition video converted to 35mm print film can be indistinguishable and thus quite useful for mainstream filmmakers who still want a feature film print release.
