WinFF is free video converter for Win Xp to Win 10, Debian, and Ubuntu. WinFF has been used around the world to help people post their videos on the internet despite repressive regimes.

WinFF 1.5.5 is mostly just a cleaned up and repacked winff 1.5.4 for possibly the final version.

For now (and maybe ever), I am going to be hosting winff on my personal site.

This maybe the final version of WinFF except for preset updates. The WinFF website is being retired after 10 years. Thanks to Paul Gevers, Ian Stoffberg, and all other contributers for all you have done.

  5. Hi, there's a bug in WinFF, where it doesn't support Unicode-named files in Windows (but works on Linux).

  6. Thanks Big Matt! This worked perfectly in a bare-bones Win7Pro VMware Workstation VM. I needed to convert a ~3 minute wmv to mp4. Btw, during rendering, I believe something is executing in %appdata% or %localappdata%. That caused problems in a later Win OS that had malware protection that monitors and prevents program or script execution in those locations. Hence my decision to try a bare bones Win7 VM, which worked without issue.
