VIdeo overlays another incorrectly - background is over overlay

Question

I'm a new user of FFmpeg, and I want to insert a logo on two videos (one video overlay another) with one command.

1. FFmpeg command (ok):

ffmpeg -stream_loop -1 -i background1080p.mp4 -i input1080p.mp4 -i
logo.png -filter_complex
"[1]scale=1280:720[inner];[0][inner]overlay=70:70:shortest=1[vid];
[vid][2]overlay=10:10:enable='not(between(t\,10\,15))'[out]" -map
"[out]" -map 0:a -c:a copy -y -shortest output.mp4

When I use the above command, it works ok.

2. FFmpeg command error

However, when I apply it to the command line below, I get an error:

@ECHO OFF
Setlocal EnableDelayedExpansion
set INPUT=D:\Shorts\code\INPUT
set OUTPUT=D:\Shorts\code\OUTPUT

:: encode video:

for %%a in ("%INPUT%\*.*") DO ffmpeg -i "%%a" -stream_loop -1 -i background.mp4 -i logo.png -filter_complex "[1]scale=1280:720[inner];[0][inner]overlay=70:70:shortest=1[vid]; [vid][2]overlay=10:10:enable='not(between(t\,10\,15))'[out]" -map "[out]" -map 0:a -c:a copy -shortest "%output%\%%~na_%%03d.mp4"

pause

• Main video (from INPUT folder) video and background.mp4 have their roles the other way round and what's supposed to be the overlay is the background.

Please help me fix the error

Answer 1

Swap the order of the first two inputs i.e. -stream_loop -1 -i background.mp4 -i "%%a"
