This short guide goes through the process of getting audio from video clips shown on sites like YouTube, Google Video, MySpace, iFilm and Metacafe. Any software used in this guide is freeware.
Introduction & Requirements
FLV Extract --> This is a freeware tool that can demux an FLV video (which we will be downloading from YouTube or likewise). The download is a ZIP file. We recommend you download WinRAR also to extract the files from the ZIP archive.
mp3DirectCut --> This freeware software will allow you to cut out parts of the resulting MP3 files that you don't want to have on the track.
We will also be using a website, VideoDownloader.net, in order to save videos from websites to computer so the audio can be extracted.
A word about quality
There is no doubt that sources like YouTube and MySpace are filled with music that you would like to have without needing to go online to hear it. You often find live fan-made recordings of performances at concerts or see promotional music videos posted by record companies. YouTube and similar site use the Macromedia Flash video format (FLV). The audio within these files is already MP3, although compressed as VBR MP3 for better streaming. The sampling frequency of these files is generally 22kHz, which is quite a bit lower than CD audio's 44.1kHz. Even so, some videos on these sites, posted by normal users, have audio you simply cannot get elsewhere.
So first thing's first... copy the entire video(s) to your hard drive.
Rip/Save video to computer
The first thing you need to do is get the video out of that little box in your web browser and on to your computer where it can be played and opened with FLV Extract. This is down easily with VideoDownloader.net.
VideoDownloader can help you to save video from several popular sites online. Among the list of supported sites is of course YouTube, Google Video, iFilm, Metacafe & MySpace. This guide will work with these sites and more, but the examples in this guide are from YouTube.
Enter URL
You will see on VideoDownloader that you have to paste in the link of the YouTube (or otherwise) video. For this guide, I am using one showing a performance from a band called Royseven. If you want to practise, then follow everything exactly as I do it. The video is located at...
Copy the video link by selecting them with the mouse and either right clicking and selecting Copy or just hitting CTRL + C. Now go to VideoDownloader.net and paste it into the field as shown in the picture above (right click in the text box and select Paste, or click in the text box and hit CTRL + V). Now click Download and you will notice that underneath this box a new area will appear giving you the chance to download the video directly.
Download Video
You will now be able to download the video. The "Download Link" button is what you need. What I recommend is you right click the Download Link and select "Save Link As" or "Save Target As" depending on what browser you are using.
This will now give you the chance to name the file before it gets to your hard drive. Any video you try to get from YouTube would automatically be saved as "get_video" otherwise. However, you need to make sure the file has an extension of .FLV
You will now get a chance to select where to download the video, so pick a folder. You now need to save the file as an FLV file so change "Save as Type" (might be "File Type" or similar in other browsers) to All Files. Now give it an appropriate name with a .FLV extension. For example, mine is...
Royseven-You Cant Hide That.FLV
In my example I have saved the video and named it appropriately for later on. The amount of time videos will take to download will depend on where they are coming from, how large/long they are and how fast your Internet connection is. At least they can be just left download in the background.
Plugin for Firefox
If you are a user of the Firefox web browser, then you can get a plugin for VideoDownloader easily which will put this small icon --> <-- into the bottom right hand corner of the browser. Any time that you want to save a YouTube video or a video from any of the supported sites, you can simply click this icon when the video page is open in your browser and it will automatically load up the box to allow you to download the file. This is great for convenience.
To install it, simply click the green "Install Now" button just above if you have this page open in Firefox and it will load a new window with instructions and information for the plugin.
Ok, download as many videos as you want to save MP3 from. When you are done, if you would like to know how you can play FLV files on your computer, then check out this short guide. If you are ready to extract the MP3, then move on.
