<p>I've been using FFmpeg to combine an audio file (.wav) and an image (.jpg) into a video (.mp4), the command I looked up seemed to work when testing it, so I tweaked it a bit (mostly just adding the scale argument) to fit that I needed and wrote a python script to run through the whole folder and create the videos.</p>
<p>They seemed fine until I noticed one was a lot longer than intended, and when I loaded all the videos &amp; songs into VLC, every video was <em>exactly</em> one minute longer than the audio source was.</p>
<p>This is the command I've been using:</p>
<p><code>ffmpeg -loop 1 -framerate 1 -i &quot;{image}&quot; -i &quot;{audio}&quot; -c:a aac -b:a 128k -s 1080x1080 -shortest &quot;{name}&quot;</code></p>
<p>The curly brackets are just for python's <code>.format()</code> function, I've tested it with specific files just in the command prompt and I get the same output. Here's said output for a test I did:</p>

Why is FFmpeg adding a minute to videos created with an audio source & image source?

# Why is FFmpeg adding a minute to videos created with an audio source & image source?

(Asked by: username_0 on 2022-10-02)

I've been using FFmpeg to combine an audio file (.wav) and an image (.jpg) into a video (.mp4), the command I looked up seemed to work when testing it, so I tweaked it a bit (mostly just adding the scale argument) to fit that I needed and wrote a python script to run through the whole folder and create the videos.
They seemed fine until I noticed one was a lot longer than intended, and when I loaded all the videos & songs into VLC, every video was exactly one minute longer than the audio source was.
This is the command I've been using:
ffmpeg -loop 1 -framerate 1 -i "{image}" -i "{audio}" -c:a aac -b:a 128k -s 1080x1080 -shortest "{name}"
The curly brackets are just for python's .format() function, I've tested it with specific files just in the command prompt and I get the same output. Here's said output for a test I did:

There was a bug with `-shortest`. Upgrade to a recent git build (5.1 series won't do).
