I noticed that if I use the compositor, I cannot get anything in the Sequencer included in the output even if Sequencer is ticked in the lower right corner. But that's okay for the Video and Image Sequence stuff because I just add them as a nodes in the Compositor and mix their Image sockets together. But I don't understand how the audio comes into play. The only place I can place the Audio is in the Sequencer. But even if Audio Codec is set from No Audio to MP3 or AAC, there is still no Audio in the final output. It seems like Blender is ignoring whatever is in the Sequencer if I use the Compositor. How do I integrate the sound into the final video output?
