Bruce, The only environment that concerns me is the production environment. While I get your point, the fact is there is a noticeable difference between 24 bit and 16 bit regardless of the final medium. It may not make a difference to some, and of course they won't be interested in acquiring an IPAS that will support full CCIR 601 implementation of the YUV file format. But its a difference I and others I know can descern. I've come to expect a very high level of image quality and color depth from 3DS. It is my understanding that the CCIR 601 specification establishes the parameters by which a YUV file can very accurately reproduce that same level of detail and quality, more so than is true of other video formats. Which is in contradiction to Gus's comment that the CCIR 601 specification has a very limited dynamic range and poor color depth. On the contrary, the specification allows for a generally higher level of dynamic range and color depth than most source material, according to Quantel. Whether you can see all sixteen millions colors on a monitor is a moot point, as is how the final medium will "look" on trasmission. To me this is not a cogent argument for limiting or restricting the potential of the image quality and color depth as it is apparent the specification does not have these limitations. And I get more than a little suspicious when arguments like these are used to defend the implementation and approach in the design of a YUV file format. John
