What is that?
To answer your question, I'll post a Q&A from the "High Def Digest" Website with the definition of dejudder (which removes Judder...
) being provided by master video guru Joshua Zyber then i'll add my own thoughts at the end.
Here goes:

"3-D Pop"
Q: I'm just curious, when I go to these big box stores (Best Buy, Fry's, Circuit City-RIP) and watch their demos on 40-50 inch LCDs and Plasma TVs, I always see that great "3 dimensional" pop but I can't get it on my home theater. My TV is a Mitsubishi WD-73734 73" DLP, I am using a PS3 as my Blu-Ray player and Monster Cable 1000 series HDMI cables going into an Onkyo receiver then to the TV. Is it the PS3? Or the cables going into the receiver then the TV? Or is the TV just too big or the fact that it is a DLP? Should I get the TV calibrated, will that help in achieving the "3D" pop? The people that work at these stores get lost when I mention the "3D" pop and tell me "3D is not available for the TV" so any help you can offer would be appreciated.
A: There are many elements to this question. First off, yes, calibrate your TV as soon as possible. If you can't afford to have a professional calibrator brought in, at the very least buy/rent a calibration disc like 'Digital Video Essentials' and follow its instructions.
You should always be wary of the video quality you see in retail store demos. Retailers invariably set their TVs on display to crank up the Brightness, Contrast, Color, and Sharpness. This makes the picture more eye-catching on a bright showroom floor, but it'll look downright horrible in your living room.
Once properly calibrated, you may still feel that your picture doesn't "pop" as much as you expected. That's only natural. Most movies aren't photographed to have the kind of vivid "3-D" look you describe. The goal in home theater isn't to make a picture with 3-D pop. The goal is to make a picture that's accurate to the source and to the filmmakers' intentions. Once you calibrate your TV, take some time to get used to the video appearance before fiddling with the settings further. The more you watch, the more you'll come to appreciate an accurate picture.
One more factor may also come into play here. Many newer TVs have a Frame Interpolation feature. This goes by many names, depending on how the manufacturers have branded it: TruMotion, PureMotion, MotionFlow, Auto Motion Plus, etc. What this does is take a 24 fps or 60 Hz video signal and artificially creates new video frames to insert in between the existing frames. The purpose of Frame Interpolation is to reduce image judder and make motion smoother. At a first glance, it may also make the picture seem sharper, more vibrant, or more "3-D." However, Frame Interpolation has the nasty side effect of making film-based content look like it was shot on video. After a few minutes, you'll feel less like you're watching a movie and more like you're watching behind-the-scenes footage from the set of that movie. Some viewers claim to like this, but many others (myself included) think it looks atrocious. I always recommend turning off Frame Interpolation and any other image "enhancement" settings that only serve to distort the source signal.
Now onto my thoughts:
First the hardware, many LCDs are using this technology, Sony and Samsung being the leaders of it. I have a Sony XBR which has this.
Now regarding picture quality.
I have owned Plasma, LCD, CRT, lets just say i've been around the block with High Def TVs and that Home Theater is my main hobby before collecting SS statues.
While Mr. Zyber might not be a fan of dejudder, I am and it's my preferred method of movie watching. I respect film purists who want to preserve the grain which makes a movie shot on film BE a film BUT i'm not one of them.
Without going into the details how it works, in simple terms dejudder takes all that grain away (or at least hides it) and makes the movie look like it's a live broadway play or a shot on video news broadcast, these two examples being the easiest way I could describe what it looks like.
Most respected technology reviewers, even the ones against dejudder, have said that they at least respect the TV manufacturers giving the consumer the option to turn it on or off.
For me, I'm happy that Mr. Zyber included dejudder as one of the reasons on why someone might see a 3D POP in a High Def picture.
For me, all the reasons he gave are legitimate for making a movie look excellent BUT as far as i'm concerned dejudder IS the main reason why an imagine all of sudden has a 3D POP once it's turned on.
I'll go one step further and mention the fact that it doesn't even have to be a High Def source to take advantage of what that technology has to offer, regular DVD also benefits from it and sometimes it's even more noticeable on the regular DVDs because one wouldn't expect that much clarity coming form a lower resolution picture vs the 1080p of HD.
Let me tell you, the first time I saw its effect my jaw hit the floor. After years upon years of searching for that 3D POP, I finally found it with dejudder.
In essence, dejudder takes a live action film movie and gives it the same 3D POP that the HD video (not film) of Good Morning America or Jay Leno have when watched in HD and it looks as sharp as those CGI cartoon movies like Ice Age 2 and Chicken Little! What's really happening is that the Frame Interpolation is creating a smoother image, I just like to describe it as it eliminating the grain because grain is what makes "FILMS" look like a film while dejudder makes it look like something completely different regardless that the movie was shot (captured) with a "FILM" camera.
For me, 1080P/24 doesn't provide the 3D POP as much as the dejudder technology does hence why regular 480P DVDs can have just as much if not more of that 3D POP with dejudder turned on as an HD movie with dejudder turned off.
Mr. Zyber says that it distorts the souce material. What he's referring to is that it changes the Film like appearance into something he doesn't feel is respectful to the original capture of the movie, not that it lowers the quality of the picture itself.
By eliminating the grain (smoothing the picture) all that's left are the objects (actors, enviroment, cars, guns..etc) which stick out so 3D like (crispier) that you feel like they're there inside your living room, especially when your TV is correctly calibrated!
There are 2 side effects which don't bother me one bit although these are not the "nasty side effects" Mr. Zyber is referring to in his comments.
When movement happens onscreen there's an itermitten slight blur on the trailing edge on some of the moving objects, no biggie.
The other side effect is that sometimes CGI effects which are attached or next to a live actor or object, it sometimes sticks out more than when dejudder is off. Remember, it's sharpening the picture so much therefore making everything crystal clear including the CGI lines!
Neither are enough to derail what I enjoy so much of the technology.
Raiders of the Lost Ark, the regular DVD (not available in HD yet) needs to be seen to be believed with dejudder turned on. Imagine Raiders being as laser sharp as something shot with HD Video! That's what it looks like!
Seriously, go ahead and put in your favorite (non HD) DVD movie and judge for yourselves, it's like you're watching ALL your movies for the first time again! It's true, you really do begin to watch everything you own all over again to see it in a whole new way, a superior way as far as I'm concerned.
Then put on Speed Racer Blu-Ray with dejudder turned on and prepare to pee pee on yourself.
I'm not here to discuss the quality of the Speed Racer movie although yes, I enjoyed it.
What I want to say is that hands down for me, Speed Racer Blu-ray with dejudder turned on IS THE BEST motion picture image (not movie) I have ever seen in my life.
For me, it's the pinnacle of HD and the best of what 1080P/24 has to offer at this moment in time! That being said, Ang Lee's Hulk is the best 1080p picture of a non cartoony movie (like SR).
I could keep going on and on and get into all kinds of crazy technical details.
It's better if you just run, don't walk, to your nearest electronics dealer or friends house and ask them to show you what it does.
I've done that to many of my friends and now it's the only way they watch movies!
Sorry Mr. Zyber, you can continue enjoying your film grain and fighting for the preservation of the accuracy of the "original" photography. I don't feel any desire to preserve that mud, I prefer to have my 3D POP when I watch a movie regardless of the artificial means being employeed to make that happen.
It's 2009, i've enjoyed how movies have looked for the better part of my life, I just feel like it's time to move on and move forward with something new and exciting when it comes to how we watch our movies.
I've embraced this technology as something wonderful and I'm proud to advise others who are in search for that 3D POP with their HD! It's finally here within your grasps, it's inexpensive and a butt load of fun to use with real world results!
Believe me, I have a massive amount of respect for Joshua Zyber and his advise, he is a master of Home Theater who possesses uber knowledge and i've been following his different columns and blogs for years!
So to each his own.
For real, I refuse to watch a move with dejudder turned off!
I hope this helped you understand what dejudder is.
Thank you
