How do you convert FLV file format to a format that Picasa recognizes (e.g. AVI, MPEG, WMV)?

Well i've been looking around google for hours trying to find a way on how to convert a FLV (Flash Video File) into an .AVI or .MP4 Video. There's something that let's me do this type of converts?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

please add more details. what is your operating system? what type of conversion are you looking for (online or local)? – gadgetmo Jan 22 '12 at 9:34

  1. Get the latest FFmpeg build from Zeranoe
  2. Extract the executable to a searchable path (e.g. %windir%)
  3. Use the following at the command prompt

    ffmpeg -i "your flv file.flv" "your avi file.avi"

There are a lot of other things that you can do with FFmpeg, for example trying to copy the video and audio streams instead of re-encoding the FLV file (which would result in noticeable quality loss):

ffmpeg -i "your flv file.flv" -vcodec copy -acodec copy "your avi file.avi"

This may or may not work depending on the codecs used in the original file.

Well, a "lot of other things" would for example include just changing the container. The syntax you gave will re-encode the video without any advanced settings, therefore drastically reducing the quality. – slhck Jan 22 '12 at 13:22
I would doubt the "drastically" bit. Depends a lot on the content itself. – IUnknown Jan 22 '12 at 13:29
I've had very bad experiences. You're right though, as always, it depends :) – slhck Jan 22 '12 at 13:29

If you want something quick you can use:


or you can google it:

You don't have to download any programs for these, you just upload your video online and download the converted file.
