I would be sure all the text is in one line, e.g.

ffmpeg -y -threads 16 -i $FILE1.mp4 -i vidasa11.png -filter_complex [1:v]scale=100:-1[logo]; "[0:v]scale=720:576[vid];" [vid][logo]overlay=590:40[out] -map [out] -map 0:a -preset slower -profile:v main -level 3.1 -c:v libx264 -g 24 -bf 3 -b_strategy 2 -coder 1 -r 25000/1000 -b:v 1650k -maxrate:v 1650k -minrate:v 1650k -bufsize:v 330k -flags +ilme+ildct -x264opts bff=1 -color_primaries 1 -color_trc 1 -colorspace 1 -c:a mp2 -b:a 128k -nal-hrd cbr -muxrate 1900k -f mpegts $FILE1.ts &> output.log &

or alternately paste this into the terminal:

ffmpeg -y -threads 16 -i $FILE1.mp4 -i vidasa11.png -filter_complex  \
[1:v]scale=100:-1[logo]; "[0:v]scale=720:576[vid];"  \
[vid][logo]overlay=590:40[out] -map [out] -map 0:a -preset slower  \
-profile:v main -level 3.1 -c:v libx264 -g 24 -bf 3 -b_strategy 2  \
-coder 1 -r 25000/1000 -b:v 1650k -maxrate:v 1650k -minrate:v 1650k  \
-bufsize:v 330k -flags +ilme+ildct -x264opts bff=1 -color_primaries 1  \
-color_trc 1 -colorspace 1 -c:a mp2 -b:a 128k -nal-hrd cbr -muxrate  \
1900k -f mpegts $FILE1.ts &> output.log &

ok?
