Part 1: Alias and resolution testing - A flat image, with various test patterns.

This video is separated in a top down manner. Left channel top, right channel bottom. The top-bottom format is ideal for screens with alternating rows of parallax barriers, such as most passive consumer 3D TVs.

On Passive FPR 3D TVs, this test video will be equivalent to full 3d, since every other row of pixels alternates polarity. You can compare this to the Left-Right 3D test video found here:

Part 2: Cross talk testing - The entire color gamut on each channel, contrasted with a solid white, 50% grey, and black on the opposite channel.

First, close the right eye to see crosstalk from the right channel. And then close the left eye to see crosstalk through the left.

This is arguably the most important test of all. Ideally, the left eye never sees any of the image meant for the right eye, and vice versa. 3D depends on the left and right eye seeing completely different images. The more cross talk, the more impeded the 3D effect.

Although it's typical to see some crosstalk, brighter than 80% (see lower right quadrant) is fail. Always pick the screen/projector/glasses with less crosstalk. If you're using red/cyan glass for 3D, you can also use this part of the video to compare glasses.


Part 3: Sync Testing - Flat vertical motion at varying speeds.

This part tests for time sync between the left eye and right eye, which can be a problem for any 3D technology that continually switches between a left image and right image, such as displays with active (battery powered) shutter glasses.

Off sync left/right channels may appear as stuttering or unexpected depth.


Part 4: Parallax and depth testing - Points that test 3D comfort.

The recommended viewing distance for 3D videos is as close as 1.5 the width of your display. And as far as 3 times the width of your display.

The absolute maximum recommended parallax for 3D Videos is 5%
A maximum comfortable amount of 3D is around 1.5% to 2%
A suggested typical amount of 3D is around 0% to 1.5%
A noticeable amount of 3D is one tenth of a percent
The 10% portions are for testing only. Never use that amount in real life. It will result in puke.
