Extract audio and video files from FLVs with FLV Extract
FLV Extract is a free program that can save video and audio files from FLV files in their original formats without decompressing or re-compressing.
If you weren’t aware of it, FLV files are containers that house audio and video files which may be encoded in any number of formats. FLV Extract gives you the ability to unpack the video and audio files without needing to re-encode or re-process.
This little program will be very useful if you (a) are downloading music from music-sharing sites in the FLV format, or (b) need to demux the audio or video from FLV files.
Converting FLVs to MP3s is possible using a number of programs such as Super or Any Audio Converter; however, these will perform re-encoding operations which take time and in most cases require that the user make a number of quality and format decisions. With FLV Extract, however, the extraction happens in a flash and is almost instantaneous, and the files retain the format and quality with which they were encoded. Here are more notes on this program:
- Nothing to install: just unzip and run.
- The UI: a simple dialog with 3 options: extract video, timecodes, and audio. All you need to do is to drop files onto the app for processing.
- Performance: you can drag multiple FLVs onto FLV Extract and they will be processed immediately within the space of a second (or a few seconds at most).
The verdict: although I do not expect this to have a very broad audience, those of us who need it will greatly appreciate it. Simple, straightforward, and free — just the way I like my software.
Version Tested: 1.3.0

Brilliant. Exactly what I need.
Nice, and very handy! No-Install is a BIG Plus, and my only suggestion for an improvement would be to allow it to function when added to the ‘Send To’ right-click menu! Of course, that might increase the program’s size, which is one of it’s great features!
The author’s other programs are nice, too – I LOVE “RotateCalc”! Makes straightening photos a Snap!
Small, Clean, Portable, and Works Well – Can’t beat that, THANKS!
Wooow, thanks…
works very well, and super fast. should complement dvd slideshow nicely, as well as all vid and audio fanatics out there. Now if transcoders only worked this fast.
excellent

Does anyone know if there is a way to recombine the video and audio tracks into a regular avi video file?
.. that’s exactly what I was looking for. Great find!
Pretty useless unless you wanna mix the vid with some other audio…or maybe just get the audio..as for extracting the vid, with no sound, can’t do anything.
It looks interesting, but with no obvious way
to download your program, I think I will
look some place else.
how do i download this?
Brilliant software
it works good, but it reduces the sound quality. When I hear the .flv version, it is louder than the extracted .mp3 version.
Unless I’m doing something wrong, I’m forced to look for another program
Just because there is a volume difference doesn’t mean the data is different.
I don’t think it’s changing the audio at all; I don’t think it re-encodes it. I’ll bet you hear a volume difference b/c you’re opening the video/audio file in a different player than the extracted audio file. Try opening them in the same program, unless you’re already doing that in which case, uh, I dunno
Not worth going thru the source code for for me 
Thanks for a wonderful little utility!
And yes, getting it to take a file as the first command line parameter would be great! That’d make the Windows “Send to” feature work!
Here’s what you do… Extract the stuff, start windows movie maker, put the 2 files (audio and video) in there on the timeline, then just export the movie and you are done!
Your flv exact is absolutely wonderful, much better than those on sale in the market. I have wanted this for along time for my flv video
[...] They are also smaller than a typical 128 kbit MP3 and although I did not extract as MP3’s (FLV Extract will do this) I am guessing that they are lower in quality than the 128kbit minimum standard for [...]

Thanks PAUWRY for the audio video seperate join tip. I think it will be useful when audio is off on FLV files. Can fix them up to match when grabbing youtube videos.
It’s what I was looking for and it did exactly what I wanted it to. For free!! Gotta love it! Thanks!
My only advice is to make the download go to bigger, it took me a while to find it. Thanks again
This is *so* amazingly perfect. Thank you, thank you, thank you.
Very useful and exactly what I needed, Thank you very much! 5 Stars
You can download YouTube videos as MP3, AVI, Windows Media Video (WMA) and many others for free.
