I have to start delivery programs as MXF IMX30. When I transcode my programs with AME the audio bitrate is ridiculously high for stereo. - 12.3 Mbps. There is no settings that can be changed. Anyone know why abode encodes the audio so high. For a 25 minute file it adds almost 2GB vs the bitrate you would expect for PCM, 1.5 Mbps.
