How to improve depth in movies Works with Nvidia Video player
If you tried watching any 3D movie on your 24" monitor, you probably noticed quite small (shallow) depth.
I know I did, and while you did have 'some' 3D, it felt... lacking.

However, there actually is a way to improve depth - at cost that there will be less popup, and possibly more crosstalk (ghosting).
But - depth is much, much better.

Using Nvidia 3D Video Player, you need to increase Parallax.
This will make bigger separation between left&right image, thus putting image more 'into' screen.
However, due to this, smaller differences in depth appear bigger this way. Image has much better depth, and 3D effect feels much better.
This way also you can sit closer to monitor, while still having good depth.
Again, only downside - less popup.

But, when increasing parallax, image will become a bit stretched horizontally.
Only easy fix I found was to crop top&bottom to keep proper aspect ratio.

For example when using 720p SBS, setting that worked for me were 80 for parallax, and 30 for top&bottom crop.

Tridef has a trial. Its media player lets you adjust stuff easily. Just an fyi.

All 2010 + Panasonic BD players have this feature as well. I just leave it at 0 to get the director's idea of how they wanted it shown. For 2D-3D conversion I have used it though. If you set it at +3 and "round" you can watch some good Blu-Ray movies convert to 3D. The "Round" feature works well because dialog is usually shot centered on the person speaking.

I think you missed the point /rolleyes.gif' class='bbc_emoticon' alt=':rolleyes:' />
If you watch 3D movies on 24" screen, you'll notice that 3D effect is very 'shallow'.

However, increasing parallax WILL improve depth feeling.
It's all in geometry :)

Check attached picture.
Blue dots represent eyes, purple screen.
Red and green dots represent two different objects, with different depth on screen.

On top picture, it is as seen as presented on movie. blue lines show difference in depth as it appears to viewer.
On bottom is same picture but with different parallax - meaning left and right are just presented more separated.
Pictures are not changed in any way, just more separated to be shown on screen.

Result is image appears more into screen, but difference in depth between 2 objects also appears bigger.

Basically effect is similar to be sitting further away from bigger screen.

So, this way you *can* improve depth feeling in movies.

Biggest issue with 3D movies is, they are filmed to be shown on big screen, thus separation is quite small so it can be presented on big screen.
Result is on small screen (monitor) depth is very shallow.
With this trick, you can improve depth feeling while sitting closer to monitor and have proper effect and feeling of depth.
As said, only 'downside' is somewhat bigger ghosting (LCD screen issue) and less popup, as things are more 'in screen'.

For me, this is huge improvement in viewing 3D movies on my 24" monitor.

PS: This is NOT about 2D->3D conversion, but proper 3D movies.

You can hotkey it so you can adjust it life.

The default hotkeys are right arrow and left arrow.

As yourself, I find the depth in movies too conservative.

Some people are hypothesizing that I have divergent vision...

Perhaps you do too. Perhaps there are more people who have divergent vision than previously thought :)

I know about shift left+right (hint: shift+right is needed /wink.gif' class='bbc_emoticon' alt=';)' />)
BUT.. problem is when you do that, picture get's stretched horizontally, so you need to crop a bit top&bottom (is I mentioned in 1st post).

And it is not about divergent vision.. it's about trying to put picture on screen appear at more depth than actually is (like having monitor 10+ meters away).

What's the difference between horizontal parallax and the "pixel separation" setting in the player? I usually use the latter (setting it to around 24) to increase depth when watching a movie

I wish I had read this thread 3 years ago! So I had to discover the importance of parallax by myself when I got my new 3DVision monitor with lightboost and wanted to check the ghosting on the new hardware. With my old monitor (1st generation 3DVision ready) I increased parallax only a little bit and could not see a significant better depth perception but a lot more ghosting. So I returned to the default 0. Besides from this I thought that depth and convergence are fixed in filmed/prerendered 3D movies at a very low level so it would not help to virtually push this shallow material away from me. I expected it would be only more distant but as shallow as before. What a mistake! As Nick7 described and explained above it can make a noticeable difference. But You really have to increase the parallax not only a little bit but to a significant level to see this effect. OK, You can't do it limitless and get the same "100%" depth we are used from gaming. Too high parallax settings will cause crosstalk. But to me it felt like increasing depth from 10% to 50%. The old versions of the Nvidia 3D Vision Video Player had issues with the aspect ratio when increasing parallax. This issues are solved in the actual version. See http://3dvision-blog.com/8619-how-to-always-keep-your-nvidia-3d-vision-video-player-up-to-date/ how to update Your player. I wondered if increasing parallax also would be a way to improve the experience with the CM as similar to 3D movies it also feels quite shallow. So I made a screenshot of a game played in CM and examined it in the 3D Vision Video Player with increased parallax. And indeed I could get more depth by this way. Of course there are limitations and side effects. Increased parallax will affect the aspect ratio of the general output so it either will cut the lateral borders or get black bars at the top and bottom. Nevertheless it would be interesting to make some experiments with this option...

Is there a player where i can change this when using my projector and active 3D glasses?

Sorry, I only know the Nvidia 3D Vision Video Player which is the Stereoscopic Player licensed for 3DVision. But You can try the Stereoscopic Player here: http://www.3dtv.at/Downloads/Index_en.aspx Maybe it works for Your equipment, too. But as You already use a projector which allows a bigger "screen" and a higher viewing distance than a usual PC monitor parallax might be not so important to You...

The PS3 allows you to select screen size, this can help depending on your seating position and image size. https://www.youtube.com/watch?v=G_4DQCoX_zY Arcsoft WinDVD also allows manually setting screen size, but unfortunately it hates Display Port connections and has issues with engaging 3D, as well as HDCP and surround sound mixes. But perhaps it will work for your setup. try the trial

Hmmm, I never actually tried this out. But a movie I was watching seemed flat, so maybe I'll rip it and give it a go. this was with a stand alone player on my Tv To bad TriDef went tits up, I never tried their player either.
