Why is it when you videotape a computer screen...?

The flicker is caused by two things: \n\nA difference in the scanning frequency between the TV and the camera \nA difference in the way the phosphor dots are perceived between the human eye and the camera's image sensor\n\n\n- My addition - \n\nEven if both devices are operating at - say - 30 frames per second (how fast the screen updates), you might be catching the image in the middle of an update (very likely, considering how fast this occurs).

that means your video has a bad encode, and your program can't read it.\n\nYOu'd have to reencode/recapture your source video.

some times it happend due to spyware or warms..\nPls scan your system using microsoft anti spy ware..:-)

Your computer is apparently using 64MB for the video. Different programs will read this differently...Either the full amount of physical memory or the amount of memory left  after the video hogs it...

This is how films are recorded, they all are made this way and then modified to fit youir screen, but more commonly you will see less and less modification and anything less than high a def TV will be obsolete.  Sooner or later even all cable will be broadcasted this way and without a high def TV you will see the annoying black bars accross the screen. I hope this anwers your question

There can be two reasons why this might occur, one is that you might have a lower connection speed to the Internet.  As you know, video transmission requires a high speed Internet connection.  If you have a slow connection there will be freezing.\n\nThe second reason may be due to lack of sufficient resources on your computer.  Video processing is a computationally intensive process and requires lot of system resources.  Try to open fewer applications when you have turned on your cam.  In addition, you can increase your system resources using steps mentioned on this website:

My sister got an LCD monitor (not sure if it was TFT or what) and it had an image of her MSN permanently showing through the desktop wallpaper. SHe was on MSN a lot but only had the monitor for a month!\nI did not realize that LCDs could burn images like that. I am glad I still have my CRT right now.

Some of your pictures on your computer can be fuzzy because your graphics card is bad old or small,  it also can be because your screen is bad.

Please do not try to record incoming webcam, it is dangerous because you are playing with other people's privacy.  Please respect other people's privacy....

When you press "Print Screen," what happens? Does it just not work, or the graphics are messed up, what?\n\nTry restarting your computer if it just doesn't take a screen shot, sometimes that happens to me when I try to take a screen shot. I don't know why that happens, but the computer just stops taking screen shots after taking a couple already.

Make sure that your computer isn't set to run at a super-high resolution. The resolution might be higher than the monitor actually supports, so some stuff might get cut off (my old laptop did that).

they cant make your monitor a camera...however they can view whats on your monitor remotelyt from their pc if they hack you

It has to do with the sampling speed of the digital video camera, and the refresh rate of the computer screen. It also is connected with the length of time that it takes to expose one frame in the digital video camera. \n\nIf there are successive images presented often enough, the human optical system interprets it as continuous movement. This is called the phi phenomenon (see reference).\n\nIf the computer screen updates at the same sample rate as the digital video camera, and there is no phase difference, then the digital video camera will show the screen exactly as humans view it. \n\nIf there is a phase difference between the two, this will appear as a flash on the digital video camera as the scene changes while the camera frame is being exposed. \n\nIf the computer screen updates slower than the sampling rate of the digital video camera, then one might see a flash during those frames when there is a screen update if the inherent exposure time of the CCD elements is too slow. \nThis will happen if the sampling rate of the camera is not an integer multiple of the refresh rate of the screen. If the sampling rate of the camera is an integer multiple of the sampling rate of the camera and there is a nonzero phase difference, then again one will see a flash when the screen updates. \n\nIf the refresh rate of the screen is sufficiently fast that the interval between successive screens is very short, then the fact that the CCDs in the digital video camera will integrate over the flash, and it might not appear, but the picture might be a bit blurry, especially if there is a lot of movement in the screen's image. \n\nThis is not really the Nyquist sampling effect, which is what happens when something of very high frequency is sampled at too low a frequency. However, if the motion on the screen is something like a wagon wheel turning rapidly enough that the sampling rate of the digital video camera is not at least twice the rotational frequency of the wagon wheel, then there will be a Nyquist-type effect; the wagon wheel will appear to be stationary, or even going in reverse.

Just try depressing the "print screen" key while you are looking at the video.   If you have one it should capture and play back.\n\nHope that helps.

its just a SHOW OFF thing..\n\nno hacker would tell that....\n\nJUST SAY THANK YOU..because i can finaly try my new found NUKER WHICH is set to nuke anyone to access my damm PC...\nand it causes your pc to be raptured.... :)

it has something to do with dvd ripping i think.. it aint malicious or spyware

Could be they are using some kind of flashmedia that's  not compatible with what you have on your computer.
