In CCTVcad, If I created a camera of 2592 x 1944, to simulate a 2X digital zoom, would I view it in the 3D viewer and got to IMAGE PARAMETERS / PROCESSING and adjust the resolution there to 1296 x 972 ?
Yes. It is more convenient than changing camera parameters. Digital zoom is an image processing in essence. But do not forget to change lens focal length.
Here is some information about modeling resolution.
First of all, VideoCAD allows to set different numbers of pixels (Horizontal and vertical) and horizontal resolution (TVL) for each CAMERA MODEL in model database. This feature allows to model image sensor and lens resolution.
In addition you can set different numbers of pixels for each camera in the project on the Processing tab, as output image after processing might have number of pixels differed from camera model. Digital zoom is a particular case of image processing.
On the same tab you can change Sharpness-Smoothing and Compression.
Resultant resolution of 3D image is calculated and modeled on the basis of entered values. Calculated resolution applied for image in archive.
Also on the View tab you can set Horizontal number of pixels on the Screen. As number of pixel on the screen can differ from native image resolution. Vertical number of pixel is calculated using Aspect ratio.
Thus VideoCAD allows to model image resolution very precisely and flexibly, but it demands understanding from an user for effective working.

Also as a side note, v6.2 does not seem to give an option of where the "save JPG or BMP" are saved to.
If they are actually being saved, I can't see where.
The same under monitor gives you an option of where
I have just checked saving 3D image to BMP and JPG. It is OK.
Some old versions have simular bug, but the bug is fixed in 6.1 version.
If it is possible, see the file C:\Documents and Settings\<user name>\Application Data\CCTVCAD\VideoCAD6\Directories.ini
In the file all open/save directories are stored. See line 'image3d='. May be the line contains nonexistent or inaccessible directory.
