128kbps Extension Test - FINISHED Reply #150 – 2003-08-09 12:17:14 QuoteQuoteand i think you meant normal wma9 as the pro codec cant be used below 128 afaikOh, yeah? I sincerely don't know.Can someone with Windows Media Encoder 9 check out if you can get a 64kbps two pass VBR encode out of it in WMA pro? Nope. CBR minimum bitrate is 128kbit. The only way to get it below that is using the Quality VBR mode, Q10 and Q25 give bitrates below 128kbit, maybe even Q50, but the bitrates these modes spit out depend on the input you feed the codec.
