[FFmpeg-user] Escaping/Quoting Problem

[Alex]

Hi all,

I still have problems quoting/escaping my ffmpeg command:

/usr/bin/ffmpeg -y -i /dir1/dir2/dir2/dir4/file.mxf -filter:v yadif -s
"1920x1080" -aspect "16:9" -r 25 -b:v 8000k -bt 8000k -vcodec libx264
-pix_fmt yuv420p -f mp4 -pass 1 -fastfirstpass 1 -an -ss 00:00:00
file_out.mxf && ffmpeg -y -i /dir1/dir2/dir2/dir4/file.mxf -f lavfi -i
"amovie=/dir1/dir2/dir2/dir4/file.mxf:si=1 [a1];
amovie=/dir1/dir2/dir2/dir4/file.mxf:si=2 [a2]; [a1][a2] amerge" -filter:v
yadif -s "1920x1080" -aspect "16:9" -r 25 -b:v 8000k -bt 8000k -vcodec
libx264 -pix_fmt yuv420p -f mp4 -pass 2 -fastfirstpass 0 -strict
experimental -c:a aac -b:a 320k -ac 2 -ar 44100 -ss 00:00:00
/dir1/dir2/dir2/dir4/file_out.mxf 

with the following bash error:

 Metadata:

It would be great, if someone could help me to correct this command.

Thanks in advance,
Alex
