I exported a windows media video from premiere cs5 (it was shot with the cannon 7d).
The video has 1 video channel, 1 audio channel that contains a conversation, and another audio channel that contains only music.
After I exported it, I imported the video into After Effects cs5, I added some effects, and then I exported it as a windows media video.
The audio settings were:
codec- windows meida audio voice 9
audio format- 20kbps, 22.05 khz, mono
Even though the video from Premiere was flawless, the one from After Effects contains the conversation perfectly, but the music is very low and even erratic.
