[FFmpeg-user] -filter_complex Gudiance Needed

[Steve Kelly]

Struggling to get -filter_complex to work. Source file is an MXF with 4 mono audio streams. I want to take the first two audio streams, convert them to 16 bit and map them into a stereo stream and re-encode the video to a prores MOV

ffmpeg -i "TEST.MXF" —filter_complex "[0:1][0:2] amerge=inputs=2, aformat=sample_fmts=s16:channel_layouts=stereo [a_out]" -map '[0:v]' -map '[a_out]' -codec:v prores -profile:v 3 -codec:a pcm_s16le "TEST_CONV.mov"


Gives an error of "[NULL @ 0x2154200] Unable to find a suitable output format for '—filter_complex'
—filter_complex: Invalid argument"


Console output below:

ffmpeg -i "TEST.MXF" —filter_complex "[0:1][0:2] amerge=inputs=2, aformat=sample_fmts=s16:channel_layouts=stereo [a_out]" -map '[0:v]' -map '[a_out]' -codec:v prores -profile:v 3 -codec:a pcm_s16le "TEST_CONV.mov"
