Ive watched a few side by side 3D movies and the 3D did seem that great. The depth was good but the 3D effects as far as far stuff coming out of the screen wasn't that great and was almost non existent it seemed to me. When I watch top and bottom 3D the 3D is good and the effects are much better than side by side. Since I'm new to 3D is this norm or are my settings wrong?

I find screen pop is very much reliant on the content and not the format.

Thanks, I also notice that with side by side when 3D gets to the edges it gets blurry. Wasn't sure if this was the content or just side by side.

It would be interesting to directly compare the same title on different 3D formats. One of the techno rags should take this on for us. Would make for some actual interesting 3D reading, rather than the mass of negative information about 3D itself currently swilling around.

I have never seen any top and bottom content even though my TV is compatible with it.
Where did you find it?

SBS is everywhere of course

I watch 3d sbs all the time and it has excellent pop I think images coming out of the screen mostly depends on how big your screen is im projecting on a 94 inch screen and with sbs 3d and the stuff comes out right up to my face.

It doesn't matter which method you choose for active 3D displays.

Theoretically, TaB is a better choice than SBS for 1080p and 720p content that is viewed on a passive 3DTV. With TaB, only the vertical resolution would get downscaled, whereas a SBS image would have both its horizontal and vertical resolution halved by the passive tech. I honestly haven't noticed much of a resolution difference between the higher quality SBS and TaB videos on my passive Vizio TV.

3D quality, depth, and pop are highly dependent on the content itself though. It all depends on the director or effects specialists and how far apart they separated the images to make depth to recede into and pop-out extend out of the screen.

Thanks guys. I watched a few free Under The Sea SBS clips I downloaded in MKV format and I expected the screen to pop but it didn't. One of the scenes was the one with the underwater snakes didn't feel like I saw any pop out of the screen effects at all which I expected to see.

I don't know much about the technical side of 3d, passive vs active etc. I have an optoma hd 33 on a 108" screen and I watched ultimate wave. I could reach out and touch the fish.

I watched that on demand too and the 3D was great

Format has no effect on popout. Creative decisions in the shooting process as well as in the editing room control popout. What you observed with the tb and sbs clips was just a coincidence.

Or his sync was reversed on his glasses? Assuming active glasses on that possibility.

Are you using a projector? I bought a new 3D epson a few months ago and was using keystone adjustment. The 3D looked good, but now that I have it celing mounted properly and not using keystone anymore, 3D looks amazing. It made a slight difference with 2d, but in 3D I think use of keystone definitely has detrimental impact on the image.

If you're using a flat screen, then disregard

For a given size TV and viewing distance, the 3d depth should be equal between the two formats. The 3D depth gets less the closer to the screen you get i've noticed, while the increasing the screen's size [i think] also increases the depth/popout since the same image are just getting wider on the bigger screen. You can always just think about what your eyes are doing to figure it out. The straighter your eyes are, the further away it looks and/or bigger in some cases (Great for viewing statues and other large structures). The more crossed your eyes are closer/smaller it looks.

In gaming, some people like whats called the "doll house" or "toyification" look, where you increase the width between the camera viewpoints, causing your eyes to cross to when viewing everything and making everything in the game world look like a toy set. On the other hand, there are people like myself who actually increase the maximum separation just a tad so that objects on the horizon are actually a little farther apart than my eyes are wide, giving majestic scenery a sort of majestic look, which is actually what i use in the videos in my signature. If you have something near a 46" 3DTV (and you can figure out how to download my videos onto your TV) you can see this effect yourself.
