Settings for available video input options:

1. Name

2. Use

3. Video Mode

For a description of these, please see above.

If you select a new card or change the video resolution, the change will only be activated when

the application is run the next time.

● Enable Crop: When switched on it trims the incoming video at the edges. Normally,

there are certain parts of the video input signal that are not visible because these are

outside the visible area of a video display. But in Nemo, if you apply the video as a

texture these would be visible and annoying. Cropping solves this and it is also very

useful in combination with Chroma Keying, if your blue (or green or whatever)

background material does not cover the whole screen. In this case you can use cropping

to cut away those parts that could not be keyed out because of the incomplete

background material.

● CropL, CropR, CropB, CropT: The size of the crop at each edge, measured in pixels. In

the order in which they appear: L (left), R (right), B (bottom) and T (top).

● Grab Input: It captures the input as a still image and offers to save it to disk in a bitmap

format.

● De-interlace: As an option for the grab, if this option is on it blends the two fields

together to help with the problem experienced when capturing a still image that contains

fast moving parts.

If the video standard you use is not interlaced (e.g. 720p) you should not deinterlace, it

just ruins the image.

● Adjust chroma key: When switched on it allows chroma keying and the adjustment of its

parameters. In Nemo3D V3.0, a completely new chroma keyer is introduced which is

faster and a lot more precise than the previous one. These are its controls:

- Enable: You can switch chroma keying on and off.

- Show input: this option displays the captured video full screen to help you see the

effect of each setting.

- Show matte: If you switch this option on, the matte created by the key will be shown.

Keyed out parts will be black, foreground – unkeyed – parts white, partially keyed parts

somewhere in between, as a a shade of grey.

- Antialias matte: To make the edges of unkeyed parts smoother, you can add a subtle

blur to reduce the aliasing effect. Particularly helpful if your video source is compressed.
