Page 1 of 4: Introduction

Flash Video (FLV) files are becoming more common due to sites like YouTube and Google Video. While there are dedicated players for FLV files and some multimedia players like Media Player Classic already has built in support for this video format, converting FLV to AVI is still sometimes preferable as AVI support in software and hardware is much more common. This guide shows you how to convert FLV video to AVI.

Our YouTube, Google Video Download and DivX Conversion Guide already covers how to download the FLV file from embedded video and also how to convert the FLV file to AVI using Dr. DivX. This guide does not cover the FLV download part and uses a slightly more complicated method for FLV to AVI conversion, but it is much more flexible and allows conversion to XviD and any other AVI format. As such, this guide is aimed at people that are at the very least familiar with the concept of (single and double pass) video encoding using VirtualDubMod, and if you are not, please refer to the YouTube, Google Video Download and DivX Conversion Guide instead.

nice post! It works for me :) Only the quality from mine movie (got it from video.google) is 320 by 240. Someone knows how2 give mine movie some better quality?

I don't have the streams menu / stream list option in virtual dub, can anybody help me out? I'm having to convert mp3 to wav in order to get sound on my outputs thus bigger than needed file sizes. Please help me out if can.

I've sorted it myself, turns out I was using a later version (1.6) where this function has been dropped.

hatemailme: The guide uses VirtualDubMod (which has the "Stream" menu), not VirtualDub (which has the "Audio" menu, with similar functionalities).

Nice guide, but the latest version of FLVextract is telling me that my .flv file uses 'Nellymoser' audio which can't be decoded. How do I extract the nellymoser audio from my FLV fle?

Hi there, i followed this to the tee but seem to be having trouble merging two avi files together now because of the audio. VirtualDub says that the sample rate is different and VirtualDubMod says that the audio has different data formats, either way i am stuck, any ideas? Thanks in advance Rob

I use a totally different way That is completely LOSSLESS .Flv conversion to .Avi with Virtual Dub Mod ,By enclosing the .flv into an Avisynth envelope. Then then Virtualdub or Virtualdub Mod will read it as if it was an avi . then you can edit the flv ,then save it to ANY format and there will never be any audio synch problem like the way listed here...its all done with not going into the audio stream or anything ! you can use this method to use a lot of formats into Avi.. like MOV,SWF, and tons more formats..try it ... this is not my specialty but it so easy to use virtual dub for everything ,I had to post this response....for the guy that wants to convert the videos from direct upload from youtube that has the stupid nellymoser audio codec this way will not work for nellymoser...but the way to do that in which i had success is to convert the nellymoser audio to wave , then mux it in with vdub ...thats all....... The End - :) Jayson

I have never used Avisynth, how did you enclose the .flv into an Avisynth envelope?

Works a treat! Thanks very much, has solved a long-standing problem for me :-)
