This scene was a (failed) attempt to make a HRD video with the output from 2x cameras mounted horizontally - one set at neutral and the other +1.5 - the result was loss of high end i.e. the sky was washed out - 3 cameras were needed - however, when 2x stereo tracks were re-combined (4x channels separated by space) the sound was extremely realistic - deeper and even slower in cadence.
If it didn't take so long to process (over 8 hours for a 14 second clip) I could have experimented with the exposure and got the sky back - However, this video supports the general belief that more is better when it comes to HDR and Audio tracks.
