Entire log at bottom...

Odd. Not the comma syntax is having an effect + generating incorrect pass through.

     ffmpeg -fflags +genpts -i "test.mts" -map 0:0 -c:v libx264 -crf:v 18 -level:v 4.1
            -profile:v high -tune:v film -preset:v veryfast -maxrate:v 3000k -bufsize:v 6000k
            -vf setdar=dar=0,setsar=sar=0 -x264opts colorprim=bt709:transfer=bt709:colormatrix=bt709:fullrange=off:analyse=0x3,0x133
            -movflags +faststart -r 29.97 -map 0:1 -c:a libfdk_aac -profile:a aac_he_v2 -afterburner 1 -signaling explicit_sbr -vbr 5 -ac 2 -ar 44100
            -metadata title='Test (TC)' -threads 0 -f mp4 -benchmark Test-1920x1080-veryfast-crf18-3000k-tc.mp4

Generates this...

Notice the final x264 settings are analyse=0x3:0 instead of analyse=0x3,0x133 as specified.

Suggestions?
