Frequently asked questions
Is ASF to FLV a lossy conversion?
Yes. FLV holds H.263, VP6 or H.264 video with MP3 or AAC audio, so the ASF's WMV video and WMA audio are re-encoded, which discards some detail.
Why convert ASF to FLV?
FLV was the standard for Flash-era streaming sites. Conversion suits legacy players or pipelines still built around Flash Video.
Where does an FLV file play today?
Flash has been dead since December 2020, but VLC opens FLV on any platform without Flash. General device and web support is now limited, so MP4 is usually more practical.
Will a DRM-protected ASF convert to FLV?
No. DRM-protected ASF/WMV cannot be converted. For unprotected files, WMA audio is re-encoded to MP3 or AAC and Windows Media metadata is not carried into FLV.
