[FFmpeg-user] filter_complex

[Mettavihari D]

Greetings

I need a bit of help to understand how to use filter_complex
I have a video file where I need to insert a logo in the video file.

I have been suggested the following command

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 &

when I run the command this is the output I get.

Filter scale has a unconnected output

This is my log file.

editor at Mettavihari:~/compress$ cat output.log
./logo-comp-10to11-V0.sh: line 24: [0:v]scale=720:576[vid];: command not found

Any hint on corrections in the command is much appreciated.
