Hi: Just for my own interest, I would like to see some 10,920x10,080 pixel progressive [non-interlaced] WMV video signals which have been produced by sampling and quantizing SECAM analogue video signals in response to sampling pulses having a sampling frequency of 15625 Mhz for the horizontal sample rate, 500 Khz for the vertical sample rate, 425 Ghz for the "blue" line subcarrier, and 441 Ghz for the "red" line subcarrier. Despite the astronomically high pixel resolutions and sample rates, the WMV coding should compress the color resolution so much that no matter how long the WMV file, the file size will only be 1-bit. Obviously this would require some intense WMV color compression after the WMV file has been encoded. After the WMV file is made, the color-resolution is reduced sufficiently to make the file size only 1-bit regardless of the length of the file. This means a longer file would require more intense compression than a shorter time -- e.g. a 5-minute WMV file would need more intense compression than a 1-minute WMV file. How would this video look like? I imagine that the pictures and their motions would be VERY clear with no skipping. The only artifacts would be those affecting the colors. These artifacts would be very extreme because of the infinitisemly small color resolution. Do I guess right? Thanks, Radium[ Auf dieses Posting antworten ]
