My only credentials are that I spend too much time on these here forums.
But Ill lay my cards out on the table for you, if you wish to counter my arguements, please do so.
Ok lets get started....
A film is 24 frames per second. A Tv is 60 frames persecond(on a progressive display as we have here). In order to get 24 to fit into 60, the first frame is shown twice, the second frame is shown 3 times.
11-222-33-444-55-666-77 and so on.
We all know this as pull up.
Since the effect is to make some frames last on screen longer than others, thus introducing time artifacts known as "judder".
Now the best way to fix this would be to display the 24p source at 24 fps, or any multiple there of. We can do 5:5 pull up on a 24p source and have it run at 120hz, smooth as it was in the theatre.
Now if a TV has 24hz input, yet can only display at 60hz, the only thing it can do is apply 3:2 pullup, to get a 60hz signal to display.
If what this TV is displaying is always 60hz, why does it matter that it came into the set at 24hz or 60hz. Its all a matter of who is doing the pullup, the Tv or the BD player, now tell me what the difference is?
There is a misconception that proper film detection is needed on all 60hz signals.
On a 1080i60 source, the TV assumes its effectively 30fps, and will deinterlace the frames a number of ways, such as combining the feilds. This works OK for video, but for Film it ends up combining the wrong fields, thus making a displayed frame actually a hybrid between to different frames.
This is why Film detection is needed.
On a 1080p60 source, coming from a BD player, the frames are not interlaced, thus they do not need to be pulled down in order to reform them. And they are already in a 3:2 pattern. They are completely ready to be displayed, they need no tweaking.
This TV having 24hz input is merely gravy, its an added convienience that no one will complain about. But unless this TV is 120hz, or uses some sort of motion interpolation to fill in frames instead of using pullup, it makes not a difference in the world.
That the way it is, I donno how my arguement can be countered, but please do if you can.
The A3000 is a 120hz set Westa, so yes, you can see the difference.
