When I encode a video and set the audio to AAC and a bitrate of 128, the resulting audio track in the output file is shown to have a bitrate of 105k. It seems like it is always off. AC3 tracks seem to be spot on. Any idea what I'm doing wrong? I'm using the program called "MediaInfo" to look at the output file tracks. I'm encoding from a MKV file - not sure if that matters.
Shouldn't I see a 128 number there in the output file?
