In the format you view the video, the bit rate (amount of information transferrable per second) is limited. The still scenes are what they are - the picture doesn't change much; may be lip movement and facial expressions, some 10-20% of the screen, and those changes can be described in fine detail (while the not-changed parts are inherited from the previous frame). On the other extreme, action scenes have 90-100% of the screen changing from frame to frame, and to keep the bitrate in bounds the picture has to be compressed with image loss, and quite severely. This is what you see - the squares are the result of approximated color described by some arcane math formula, and it is normal. The same result can be seen in two more things : one is JPEG compression. In some sense, size of JPEG can be viewed as a bitrate and then the quality degrades if the bitrate must be limited. The other is a size/speed consideration of animated GIFs - small changes take little space, while full-screen animation takes loads of it, and (for example) full-screen scrolling might force the image to 16 colors to keep the animation file's size in limits of acceptable. +=-. | Max Timchenko [MaxVT] | [log in to unmask], [log in to unmask] | (ICQ) 238-6792 | | Freelance website and graphics designer | Max Webdesign at http://maxwd.hypermart.net | | Editor - Graphics artist | NOSPIN group +=-.
