Need help sorting surveillance videos

[pepsi44]

Hi there, so I have 120+ videos from my surveillance camera located in the backyard and I don't want to watch 48+ hours of video footage. I was hoping someone here knows a program that can sort videos by their noise level? I want to take all the videos with high levels of noise and cut them into a single video, that's the easy part. The hard part is finding the videos... So, does anyone know a tool that can help?

Do you really mean noise or do you mean "audio"?

[pepsi44]

Oops, sorry, I mean the audio. Since the videos are nearly dead silent when a "disturbance" isn't occurring.

You could do it with FFmpeg and a batch file.

for %%F in (*.mp4) do (
    ffmpeg.exe -i %%F -vn -af volumedetect -f null nul 2> volumedetect.log
    for /f "tokens=5" %%G in ('find "mean_volume" volumedetect.log') do (
        set V=%%G
        set V=0!V:~1!
        set V=!V:~-4!
        echo !V! %%F >> volumelist.txt
    )
)
sort /r <volumelist.txt >volumesort.txt

Thank you for the link and the code. It sorted the videos but volumesort.txt returned all the videos. I guess it's still detecting background noise. How would I make the audio detection more lenient? The audio I'm searching for is quite loud.

[JVRaines]

The result is all videos sorted in order of decreasing average volume; the videos at the top of the list have the highest average volume. If you want maximum volume instead, replace "mean_volume" with "max_volume."

Ah, that makes sense now. Thank you, you've been very helpful!
