I have a few hundred .mp4 files which are typically 1-2 minutes long. I would like to watch the videos, and extract small audio clips (1-3 seconds) from the videos. Those small audio clips can be saved in any format.
Any recommendations? Thank you in advance!
One solution could be to drag and drop your video into a free video editor like HitFilm Express. As you play the video, press a keyboard shortcut to split up the video into the small segments you want audio for. Then 'render' or export the video as an audio file like .wav.
All of your audio clips are in one file, but if they need to be in separate files, you could then drag your audio file into an audio editor like Audacity and split it from there.
You could use the Windows application M²Convert Professional.
There’s a “Split File” feature that lets you launch a player to select one or more portions:
Once in the player, you can play, pause, seek, etc. to get to the start/end point, mark them with the 2 bracket buttons, then click “Add”.
Once you’re done selecting all the needed portions, close the player window and click “Split” in the “Split Media File” window.
I recommend trying the free evaluation before deciding whether to purchase the application.
Note: The portions will be in a video format such as AVI or OGG, but it’s very easy to convert them to MP3 or other Audio formats in one step using the same program’s “Convert Files” feature.
Full disclosure: This application is from a subsidiary owned by the company I work for. It was developed using the LEADTOOLS Multimedia SDK
ffmpegshould be able to do that. maybe a combination offfmpeg -i input-video.avi -vn -acodec copy output-audio.aac(extract audio without reencoding) and the options-ss HH:MM:SS.msec(start) and-t HH:MM:SS.msec(length). So I would tryffmpeg -ss HH:MM:SS.msec -i input-video.mp4 -t HH:MM:SS.msec -vn -acodec copy output-audio.aac
