It's not an illusion - it's called chroma subsampling. Most video codecs do not represent colour in full resolution as a way of achieving greater compression by taking advantage of the way that the human eye is more sensitive to brightness ("luma") than colour ("chroma"). Many codecs don't bother giving you too much colour information when you're not going ...

It's a well known issue that red component in video devices suffers in presentation. The reason is the red color's long wave length and that our eyes respond more to long wave ranges (not to be confused with color sensitivity which would be in yellow-green range). For us to perceive the colors as equal (ref. responsiveness) the green and blue are ...

While pure red is tough to match, partly due to our visual sensitivity in that region, I've never noticed any tendency for red to 'pixelate' more than any other color. Maybe you're seeing an artifact of compression? Do you also see this in non-electronic displays like backlit signs, etc? Another answer here claims that manufacturers kept secrets about color ...

A long VGA cable with a proper amp/spliter on the TX side, would be the simplest option. You can get good VGA cables up to 150' at modest prices from http://www.pccables.com . Another good option is a CAT5 extender kit. http://milestek.com/p-16209-vga-over-cat5ecat6-decora-wall-plate-set.aspx Without a more detailed description of what you are trying to ...

The tuned teeth (or lamellae) of the steel comb is typically set to a chromatic scale. To change the tuning would require adding or subtracting material to an individual tooth with some trial and error and a good ear. Changing the length would cancel the action of the pins on the revolving cylinder so that is not a good idea. If you think the scale you have ...

The logo on the manual I could find indicates that it was standard 8mm, not Hi8 or Digital8. If you are in a PAL region, then most likely it is the PAL version of 8mm. You should be able to use any PAL based 8mm playback deck or camcorder to play the tape back. You then be able to use a standard video capture device to digitize the video that you ...

I think the issue you see here is actually because of bright pixels against a very dark background. Most lossy compression takes into account that we are far more perceptive to lightness differences than we are color differences. Depending on the codec used, and encoding options chosen, the blocks used for approximating the video can be fixed size, which ...

The worst part of transferring old VHS to DVD is that it has to be done in real time as VHS is linear access and analog. Here are two ways I know of that work. One will eat your time the other will eat your wallet. 1) for about $35 or less you can get a transfer device which connects the output of your VHS machine into a USB interface to your computer. ...
