How does de-judder look on videogames??

post #1 of 17
Thread Starter 
I was just curious as to what that effect would have on videogames. I've seen it on movies but not on games...does it make it distracting or does it make it better

i'm talking ps3,360 graphics...and wii as well

Why would there be judder on video games? It's native framerate isn't 24P like movies.

good point...but i've read that using the 120mhz automotion feature makes games look better

or does it make no difference?

First off it is 120Hz, if it were mhz it would be 1,000x more.

I have yet to see it on a video game, but I have seen both Ratatouille and TMNT with it on and it looked pretty dang sweet. So I would expect it to look pretty good with games, don't know how it would handle the frame rate drops in games though. Don't really care for it with non animated movies though.

on movies it gives a soap opera effect...but i think on low it might give a good balance...although action scense look cartoony and fake with it on

i really want to know what the games look like with it

Don't use it with games; it will create a lot of input lag.

It looks amazing with games! It can make a pokey 30fps game look like a 60fps. By far amp/120hz works best with games.

it doesnt do a whole lot for games. it can make slower consistent camera movement look smoother like in a cutscene or if you're moving the camera slowly but during regular play movement is so irrattic that you wont notice a difference. some tv's have a hard time keeping up with the action as well like the xbr4 which you can actually see the screen jerk into smoothing mode.


the only really noticable thing is increased lag. anyone that says it doesnt make lag worse needs to try a game like DDR or rockband with it on.

It has to AT LEAST create 1.66ms of lag because it has to wait for the next frame to be able to interpret the in-between frame and that's if it could create the frame instantaneously, so figure 2-4ms of lag is going to be added.

While it might not be a big deal for most, some 'hard-core' gamers will easily notice this addition and will make games like DDR hard to play.

How is it incorrect? It needs at least 2 frames combined to make the middle frame plus the fact that there will be processing time to combine them. There is no way around it there will be more lag.

""What is judder?
Technically, the term judder was introduced to explain a phenomenon that occurs when movies and other film sources are converted for home viewing using 3:2 pulldown, which uses 4 frames from the original to create 5 interlaced frames in the output. As a result, 3:2 pulldown shows odd frames for 49.98 milliseconds and even frames for 33.33 milliseconds. This mismatch of timing produced a jerky effect that was eventually dubbed as judder. ""

ARen't the games running at 30 or 60 fps?

^Yep, the original poster was mistaken in his wording. We are now discussing 120hz frame interpolation with games, which was what he meant.

OK. Some amount of lag will definitely be introduced. Whether it is noticeable would depend on the person and the amount of lag.

I'm on the fence with the 550 or 650 series from Samsung. If there is a minor amount of lag on games with 120hz set to high, can't this lag be corrected by setting the picture to "game mode"?

The motionflow/amp would be set to high not 120Hz. And yes turning on game mode would correct the lag because game mode automatically disables motionflow and cinemotion. You can't have them on at the same time, and for good reason. Game mode decreases lag by decreasing the amount of processing and motionflow/cinemotion increase lag by increasing processing.

It seems to me that if you are using a Samsung LCD for just movies, then it is a personal preference on the 120hz model or not. But if you are going to add in a PS3 or 360 system then its a must to get the A650 series. Agree?

The price difference between the two models is about $350 so that isn't too bad. I haven't seen a blu-ray movie on the A650 to be able to see the so called soap opera effect but I did notice the dejudder when watching an HD channel with the demo mode on. I don't think I'm too concerned about the glossy screen on the A650 since it'll be in a computer room or den that don't have lots of windows. Any tips on what I should do?
