Batch add audio to video - Adobe? I'm looking for a method to add an audio file (a short blip) to many short video files. Is there a method on any popular video software to create a batch process that will add the same audio file to many video files, so that the 'blip' plays at the start of each video?

Thanks!
Using FFMPEG the command would look something like this:

ffmpeg -i &lt;sourceVideoFile&gt; -i &lt;sourceAudioFile1&gt; -i &lt;sourceAudioFile2&gt; -map 0:0 -map 0:1 -map 1:0 -map 2:0 -c:v copy -c:a copy &lt;outputVideoFile&gt;


Basically you're taking the source video file and multiple audio inputs, then mapping multiple audio files to the output's audio stream 0. Using -c:v copy and -c:a copy, you arent doing any encoding, so your file will keep its original quality.

That command was taken from the link below, which has more instructions:

Edit: Forgot to mention the point about wanting to do it in batch. Use the link below to create a bat file in Windows that would target all the specific types like *.avi (or all types using .). You'd want to replace the ffmpeg portion of their bat file with the above. Since you have one audio file, try something like:

for %%a in ("*.avi") do ffmpeg -i "%%a" -i  -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy "%%a"

You might want to back up your files and make a copy elsewhere before you process them, because the above will overwrite them I believe.
