Hi all, I know this has nothing at all to do with computers but I can't seem to find which of the 2 is better. I have a Hitachi RPTV and it has a feature called 3:2 Pulldown, to use this option i cannot be using progressive scan on my dvd player. So my biggest question here is what is better progressive scan or 3:2 pulldown... for picture quality... i really can't tell the difference so it is not a huge deal but i was just curious about this... if anyone has any ideas at all. thanks

this would be better in the hardware dept. however, anything i find mentions that you need 3:2 pulldown with progressive scan. so, maybe you should be able to do it with both on.

Thanks for the reply, I would do that but it does not allow me to do to use both. I basically have a choice of using the 3:2 pulldown from the tv or progressive on my dvd player.

I hear that most movies are not in progressive scan format yet so the 3:2 pulldown supposbibley is better for the non progressive moives.

I think i am going to use the progressive scan because it does in facts make the picture better but from my eyes i dont see much dif.

Progressive Scan
A video scanning system that displays all lines of a frame in one pass. Contrast with interlaced scan.

Interlace
Each frame of a video picture is scanned twice. Firstly, all the odd lines are broadcast, then all the even lines are broadcast. Each set of odd/even lines is known as a field. Two fields therefore make up a frame. The point of doing this is to reduce flicker, and not increase bandwidth.

2:3 pulldown
The process of converting 24-frame-per-second film to video by repeating one film frame as three fields, then the next film frame as two fields

3:2 pulldown
An uncommon variation of 2-3 pulldown, where the first film frame is repeated for 3 fields instead of two. Most people mean 2:3 pulldown when they say 3:2 pulldown.

Telecine
Cinematic film movies are shot at 24 progressive frames per second speed. A Frame is the smallest unit of a 24 fps FILM format. NTSC video is a "field-based" format of 59.94 fields per second. A Field is the smallest unit in interlaced video format. 2 fields make up 1 frame. So, this 59.94 fields per second equals 29.97 frames per second. 1 second in FILM (24 frames) is NOT equal to 1 second in NTSC Video (29.97 frames).

To be able to match the speed of an NTSC Video, conversion from a FILM format to an NTSC Video format undergoes a process called 2:3 pulldown or TELECINE. This process, in simplest terms, means "to add 6 frames so that a 24 fps becomes 30fps which is close to 29.97 fps (another trick is used to get to 29.97).

Thanks that was good info i am going to take a look at that site
