Thanks I solved it by using the following commands using some tips from the people on the irc channel.
ffmpeg -i test/20160522_sunam_mlc_rhb.mov -c:v copy -an video.mov ffmpeg -i test/20160522_sunam_mlc_rhb.mov -c:a copy -vn audio.aiff ffmpeg -r 30000/1001 -i video.mov -pix_fmt yuv420p -vcodec libx264 -x264opts colorprim=bt709:transfer=bt709:colormatrix=bt709:fullrange=off -crf 18 -map 0:0 -map_metadata -1 -preset medium encoded/testmevideo.mov ffmpeg -i audio.aiff -filter_complex "[0:0]pan=2c|c0=c0|c1=c1[stereo]" -acodec pcm_s24le -map "[stereo]" encoded/audio.wav ffmpeg -i encoded/testmevideo2.mov -i encoded/audio.wav -c copy encoded/it_works.mov So I just split out the audio and video then processed them separately then muxed them together again. It would seem that something was getting messed by having all the processing going on at once. I'm not sure what could be different by doing it this way, but it works and I'm happy. Might be something to look into though as a potential bug, who knows? Also I could not put pcm_s24be source audio into a wav and I couldn't put the converted pcm_s24le into an aiff, not sure why that would be but it works right now so who cares. Thanks!
