It would be relatively straight forward to allow these parameters to be modified by the user thereby providing pan and zoom. In addition it would be easy to allow the frame rate of processing to be altered allowing 'slo-mo' during panning and zooming, however, as Andrew has pointed out there is, almost certainly, generic software to allow this to be done as a form of pre-processing to the original material, so it is debatable as to whether it is worthwhile adding to the Video2NBTV application itself, however if there was enough interest in doing this I might be arm twisted...

Video2NBTV is software written by Gary Millard. The blurb states...
"Video2NBTV is a programme which takes a video file (avi, mpg, mov, wmv, in fact just about anything that can be played by Windows Media Player) and outputs in NBTV *COLOUR* format (Robers/Brown colour format 32 line missing sync pulse vertical scan line format only). Note this format is Black & White Compatible, that is, the output will play back on B&W viewers/monitors. The audio track associated with the video file is extracted and placed in the right hand audio channel."
It can be downloaded for free at http://users.tpg.com.au/users/gmillard/nbtv.htm
PS: I might add that "programme" is a Television-type show, whereas "program" is a computer-type bit of software. In this case, the incorrect use is kind of ironic

But breaking a film down and selecting and manipulating frames to be re assembled is very time consuming.
One really needs to take close ups, pan and zoom on the hoof in real time, whilst the original is playing.
That is why I first mentioned using a NBTV camera in front of a cinema screen at the start of this thread.
Anyway I have decided, (well nearly!), to build a combined camera/monitor even tho' I have to position 48 holes instead of the 32.....
...I do have mechanical experience....and a NBTV beginners optimism!
A very nice example of such a machine is shown here (13th photo down)...
