[00:00] Welcome. In this video I'm going to be extracting video or removing the audio from a video file. It's two different ways of looking at the same thing. I'll put a link in the description to the commands I'm using in this video, and we'll also have a link to my FFmpeg notes where you can find the installation information,
[00:14] and a link to my FFmpeg playlist. So this is a little tricky here. I have this video called Train Whistle. I'll open it up, and this has a loud train whistle on it, but you can't hear it because I have my microphone plugged in to record this video.
[00:26] But I will show you that it does have the audio on it. So I'm in my terminal here. I'm on my desktop. I can type ffprobe and then I'll type train whistle, enter. And here we have the file and this has a number of tracks on it. Here's the video track,
[00:39] it's h.264. And then we have AAC here and this is a metadata track, timecode handler, and some other track. So we want to extract the video file from this. So I'll type clear.
[00:52] So to start I'll type ffmpeg space dash i space and then the name of the file, train whistle dot mp4 then dash v codec space copy So I just want to copy the file I don want to modify it in any way then space dash an so this will remove the audio and then space so i say train whistle no audio dot mp4
[01:12] i'll hit enter so this is a 4k file and it did that immediately the reason is is it mostly just copies things and this can copy very fast i have an ssd in here so i'll clear my screen here we'll at these two files. So one of them is 261 meg and one is 260 meg. So the audio didn't take up a lot
[01:29] of space in here. I'll type ffprobe, look at it, and here we have the video file but the audio is no longer in this. I can open it up here and here's the video file and we don't have the volume slider
[01:42] on it anymore. So this could be useful if you have a video and you need to remove the audio for privacy reasons or you just don't like the audio you maybe want to make the file smaller and you
[01:54] don't need the audio there could be a number of reasons you might want to do this so that's all for this video if you have any questions about this please leave it in the comments if you like this video please click like if you haven't subscribed to my channel i'd appreciate if you could do that and thanks for watching until next time goodbye
