How to convert flv to avi using ffmpeg high quality

Posted by: admin November 30, 2017 Leave a comment


Need to convert flv files to avi or mov, trying out ffmpeg but the output quality is terrible. How can I get the video output to be on par quality with the source?

I thought ffmpeg -i name.flv -s 320x… name.avi would do it, but no good.


That’s the command I was using for a ffmpeg project, the quality should be good enough. If not, try increasing the bitrate (-b argument):

ffmpeg -i input.flv -ar 22050 -b 2048k output.avi


This is a Good solutions

ffmpeg -async 1 -i inputVideo.flv -f avi -b 700k -qscale 0 -ab 160k -ar 44100 outputVideo.avi

Or Used following one

ffmpeg -loglevel 0 -async 1 -i inputVideo.flv -f avi -b 700k -sameq -ab 160k -ar 44100 outputVideo.avi


There is also another solution found on the internet and works like charm!

Just use same quality parameter -sameq.

ffmpeg.exe -i video.flv -sameq outputVideo.avi

Actually the command sameq is not same quality.
In order to successfully do it this one must be applied:
in case you have multiple files to do here is the complete command

for %i in (*.flv) do ffmpeg -i "%i" -q:a 0 -q:v 0 "%i".avi


To preserve quality use -qscale 0.

For example ffmpeg.exe -i InputVid.avi -qscale 0 OutputVid.mp4

I converted my 1.64 GB avi video to 4.35 MB mp4 file.
