Why does video still have filmy look even after using 3:2 pulldown method?[edit]

In Broadcast Engineering, broadcasters use telecine to convert 24fps film to ~29.97 fps video by using 3:2 pulldown method.

But why does video still have filmy look even after using 3:2 pulldown method? Rizosome (talk) 04:19, 16 April 2021 (UTC)[reply]

I'm not sure what you mean by "filmy", but one difference between digital and film images is that film has granularity, which is irregular, whereas digital images are in regular pixels. --2603:6081:1C00:1187:F010:251A:8B7B:CC6F (talk) 00:10, 18 April 2021 (UTC)[reply]

If you are referring to video that was originally shot on film and later transferred to video, and comparing that "filmy look" to footage that was originally shot with a video camera, the difference is in the two types of cameras. Film cameras focus light through their lenses onto photographic film that is exposed based on the lens settings, properties of that type of film stock, its subsequent processing, printing and projection. There are hundreds of variables that contribute to the "look" of film. On the other hand, video was formerly shot by allowing focused light to fall on various types of pickup tubes that converted the light into electrical energy that was recorded onto video tape. More modern video cameras use charge-coupled devices to convert the light into electric energy that is stored digitally and recorded as a video file. Just like film, there are hundreds of variables in a video camera/recording system. One of the most obvious differences between film and video is the dynamic range of light that can be captured and reproduced, especially what happens to the very dark and very bright parts of the scene being photographed.--Thomprod (talk) 20:17, 22 April 2021 (UTC)[reply]
