<p>I have 500+ videos. I need to add intro and outro to them.</p>

<p>Found this .bat script on a different website, and tried it. But it didn't work for me. As the script only ads outro - still didn't work.</p>

<pre><code>SET RESOLUTION="1280:720"
SET INPUT_FOLDER="input"
SET INTRO="intro.mp4"
SET OUTPUT_FOLDER="output"

for %%a in ("%INPUT_FOLDER%\*.*") do ffmpeg -i %INTRO% -i "%%a" -filter_complex "[0:v]scale=%RESOLUTION%:force_original_aspect_ratio=1,pad=%RESOLUTION%:(ow-iw)/2:(oh-ih)/2[v0]; [1:v]scale=%RESOLUTION%:force_original_aspect_ratio=1,pad=%RESOLUTION%:(ow-iw)/2:(oh-ih)/2[v1]; [v0][0:a][v1][1:a]concat=n=2:v=1:a=1[v][a]" -map [v] -map [a] "%OUTPUT_FOLDER%\%%~na.mp4"
</code></pre>

<p>I'm on Windows OS, but I also have Linux Mint installed on my workstation.</p>

<p>My question is: how to add 1 intro and 1 outro to 500+ videos?</p>

<p><strong>PS:</strong> Intro and Outro files are the same file.</p>

<p>Thank you.</p>

No errors or log? Is the problem with your batch script or the ffmpeg command?

I ran the .bat file, but it didn't give me any error. Have to mention the batch script is located in the same place as the video files and intro/outro file -> 4 videos in total for testing purpose. I have no log.
