The three streams should perhaps also differ > in resolution and not only bitrate. Not really. This is simillar to the problem of trying to requantize the stream. You could reuse some of the analysis i suppose, but when you change the rate and dimensions you end up making different coding decisions and the streams would diverge quickly. One thing you can do is reuse the first-pass complexity analysis data for multiple second-pass encodings at different rates. That will some some time. -r _______________________________________________ theora mailing list [email protected] http://lists.xiph.org/mailman/listinfo/theora
