DANS MECHANICAL SCREENSHOT VIDEO WMV

[daniel gosson]

I thought it was time to put this one back into circulation. This is a video clip taken directly off my disk monitor & is the clearest motion picture I have ever seen taken off a mechanical monitor.
The secret to this is to stop the ccd in the camera from discharging after each frame, thus the motion becomes very smooth.
Please enjoy.

Hi Dan,
Is it possible to avoid using WMV format for video files? MPEG-4 is industry standard, smaller in size and better quality. Besides it is cross platform not just Windows only. Believe it or not but some people don't use Windozejavascript:emoticon(':wink:')

Cheers,

Hello Sergei, as I'm using MacOS X, too: There is a good WMV plugin for Quicktime, which makes it possible to watch about 99 % of al wmv-files. You find it on the evil website of www.microsoft.com.

There is a program EasyWMV also that can convert WMV into MPEG-4 including H264 encoding. Unfortunately it is not free, but demo version will convert up to 1 minute of video. Which I did yesterday and the video that Daniel posted is great.

Best regards,

Wow, that's amazing Daniel. How did you do it? What camera did you use? How much modification to the camera did it require? Would it be possible for we viewers to try this at home?

Sorry for the long delay, I have been away from this forum for about a year. Some video cameras will drop the framerate right down if the light level is low. Mine does this while turning on a video light. I tape something over the light so it doesnt shine on the disk. I have put heaps of NBTV stuff on YOU TUBE, just type in 32 LINE & you have it all. actually its surprizing how many people are into this.

Hi Daniel,

How did you go about controlling the CCD parameters? I've been thinking about writing some NBTV specific video capture software but if there's a way of doing it already I'd like that!

Most recent video cameras can be made to do this if you search through the menu. It may be called nightshot or something else like that. All it does is stop the imager from refreshing with each frame, however it still outputs 25 or 30 as usual. I then increase the brightness & contrast with virtual dub because it is so faint. Because the imager only refreshes maybe 10 times a second the camera can blur the NBTV image together & stop flicker.

If you check my stuff on youtube (type in 32 line) you will see a full sise screenshot of THE BIG PICTURE running NBTV video. Because my computer has a VGA to PAL scan converter I can record NBTV from my computer onto the video in of my digital video camera.

Nice material, Daniel.

As you say plenty of 32 line activity on YouTube.

Definitely a lot of interest world wide, it's a good platform for promoting the NBTV cause.
