Possible to do quality FLV conversion to DivX or MPEG?

[keys]

If I have an AVI or MPEG and I want to clean it up and then re-encode it, I can decompress it in VirtualDub using Lagarith or HuffYUV, clean it up and then create an AVI or VCD MPEG - even a DVD and the loss in quality is negligible.

However I have an FLV file that I need to clean up and I don't know which particular piece of software to use to convert it without losing too much quality. VirtualDub doesn't handle it and I don't know of any converters that will allow me to use Lagarith or HuffYUV as a codec to then play about with.

Can anyone assist?

Hmm, ffmpeg can re-encode your flv to AVI-HuffYUV. You can also convert directly from FLV to AVI without re-encoding using FLV Extract (http://moitah.net/#FLVExtract). However, you'll need to install ffdshow and AviSynth to be able to open the converted AVI in VirtualDub.

I don't have ffdshow installed on this PC but I think you need to enable FLV or VP6 or something in the video decoder option.

AviSynth script (simple text file with .avs extension) to open FLV encoded AVI:DirectShowSource("converted-flv.avi")
return last

Just open the script in VirtualDub and you can play with it as you would an AVI file.

I did a bit of a search and I came up with this:

If you skip to page 4 someone by the name of Scorpion King seems to have put together quite a good guide. In fact it's so good I copied and pasted it into a Word doc to keep. But thanks for your answers fellas as they seem to tie in with the guide anyway.

If you enable FLV1 in VfW configuration of ffdshow, there should be no need to use AviSynth. Using FLVExtract -> VirtualDub is the simplest and highest quality solution possible.
