In the Part 1 we "discovered" the NuView Camcorder adapter as the easiest and cheapest device to capture 3D using any miniDV camcorder. (Not using progressive mode)
Given the current discounted price of this device, it does its job quite well.

Note: You have to understand that there is a reason why these devices never really took off. Current 3D experience is on the geekish side of the spectrum and has a lot of to be desired. Not everybody wants to watch their movies through a glasses (anaglyph or shutter) and the strobing effect produced by low refresh ratio displays brings a lot of fatigue to the eye.
Therefore I present it here as a way to capture some of your todays memories and bring them to the future in a 3D. It is expected that a reasonable home 3D will be available at some point. Even today a single modified DLP projector (like the DepthQ) can produce steady 120Hz refresh rate which makes watching 3D through shutter glasses far more pleasant experience. In the future projector makers may be looking for a new boost to the market and connecting shutter glasses with some support for common 3D formats (side, above-below, interleaved) may be the exact simple but effective feature.

The NuView captures frame interleaved format, more precisely interlaced interleaved format. Each field in the half frame is captured by the other eye. The device is synced with camera using the camera video output.

Convergence Control
NuView has the paralax control knob that moves the mirror and can be used to cross-focus on the main subject. The image on the camera LCD appear doubled, the goal of the Convergence control is to adjust it so the main object (person) has the left and right image superimposed. This will then appear during projection on the plane of the TV or monitor. Objects in front of it will "jump" out of TV, object behind it will appear inside TV. As we discussed in the Part 1, this is important feature, because watching the main subject projected out of TV is difficult unless you have large TV covering large part of your field of view.

Conversion
The captured video using the NuView adapter alternate fields between left and right eye. Of course, that is rather difficult to watch without a 3D decoder.

Note: I used a 16:9 camera, therefore the video captures are wide.

We discussed in Part 1 that the included NuView TV decoder and shutter glasses works only on a CRT TV's with 60Hz refresh ratio. That means even if you have now such TV, in the future it will be difficult to obtain one.

But no worries, it is simple to convert the iterleaved 3D video to any other 3D format with just a normal video tools so we are ready for any future 3D display.

1. Capture
Obviously first step is to capture the video from the miniDV camera as a DV avi. Any DV capturing tool in your NLE would do this.

2. Separating the fields
No need to buy any special tool. What we need is free and called VirtualDub. First open the 3D interleaved video we captured. Now, if the VirtualDub say that it cannot find DVSD decoder, you have to install a DV codec. One free is Panasonic DV CODEC (do a search in google).

When the video is loaded, go to menu Video, filters and select Deinterlace. Choose Duplicate field 1, then close the filters.

Open the video menu again, set Full processing mode. Then open Compression. Here choose DV codec (for example the Panasonic DV CODEC) or use other low compression easily editable codec: MJPEG (PIC Video), Huffyuv (free but large files) etc.

Then save this as AVI: Left_eye.avi

We have our left eye exported. Now go back to VirtualDub, open filters, configure the deinterlace filter and this time choose Duplicate filed 2.

Save as Right_eye.avi

At this moment we have both left and right eye separated AVIs and that's the most important part. We can now even watch either one as a normal video (Just note it has half the vertical resolution)

3. Conversion
Once we know how to separate the fields we can now make any format that our future device would require. I decided to do a 2 color anaglyph because I want the 3D video to burn on DVD and then send to my family, including the red-cyan anaglyph cardboard glasses that can be purchased in any quantities over internet for less than a buck a piece. With anaglyph we will loose some of the color, but it will surely work on their TV without any special device.

Anaglyph Conversion
For this viewer need anaglyph glasses. We will work on a RED-CYAN anaglyph as it can best reproduce the colors. Obviously the viewer would need RED-CYAN anaglyph glasses (cardboard ones can be purchased for less than $1 on internet).

For this I will use Sony Vegas, but please note, any better NLE would work the same way.

1. Load the Left_eye video as top track, then Right_eye video as bottom track. We can remove one of the audio, since the audio is identical, but may produce little echoing if we left both.

2. Select the Left_eye video and click Track FX to open effects. Add Sony Levels. In Channel select Blue and move the Output end to 0. Add another Levels filter after the first one. In this second one choose Green channel and set output to 0

This will set the left eye video to be red. Alternatively, if your NLE has no levels filter you can use Curves. In curves you simply bring the right side of both BLUE and GREEN curve all the way down so only red curve is diagonal.

3. Set the Composing mode of the Left video to Screen

4. Select Right_eye video and add a Track FX: Sony Level. Here we need only one Level. We will select Red channel and move the output to zero. This produces Cyan image.

The result composition should be already anaglyph and when using colored glasses (left eye-red, right eye-cyan) it should appear as 3D.

Note: I used 16:9 video camera - therefore the wide video capture

Note: If you see a strange effect looking through the glasses, try to reverse them - maybe you misplaced the left and right eye (for example if the NuView adapter switch is not in top position the fields are reversed). In such case simply switch the file named Right_eye as top and Left_eye as bottom in the Vegas video and do the above filter steps on the switched videos (so on right_eye you remove blue and green).
The 3D effect looking through anaglyph glasses should be clearly seen.

Now I can export it as MPEG2, burn to DVD and send to my parents. Oh, I shouldn't forget to include pair of RED-CYAN cardboard anaglyph glasses and film some instruction before the "main feature" to remaind my parents to put them on. This is a great and untraditional Christmass gift.

Later we will examine other formats and/or other NLE.

If you have the above or similar process done with other NLE, send us your instructions or tips.

Edit Studio 5 (submited by Vapymid in mmbforums.com)

Just to add for EditStudio5 users - The procedure for preparing anaglyphic video on that NLE is similar to the one described in the MediaChance's 3D Video tutorial. Use the following layers:

1) Mix (foreground = 2, background = 3, mix transparency = 128) + Brightness (multiplicative brightness = +100)
2) Video 1 + Levels (red output = 0:0 <move white slider to the left>)
3) Video 2 + Levels (green output = 0:0, blue output = 0:0 <ditto>)
4) Audio, if any

In the above I use "+" sign to show that the effects are added as "toppings", i.e. to the items themselves and not to separate layers but you can use separate layers if you so wish.

The main differences to Vegas tutorial are:

- Video 2 only need 1 Levels effect because ES5 Levels can change more than 1 channel in one instance.
- You need to use explicit Mix effect to overlay two video layers
- You need to increase the brightness to compensate for the levels adjustment
