What to expect

  • Streams are re-encoded to FLV-supported codecs (lossy); quality cannot improve over the source MOV.
  • FLV is a legacy Flash-era container; it plays without Flash, but MP4 is far more universally supported today.
  • QuickTime chapters and some metadata may be dropped in the container change.

Frequently asked questions

How is the quality after converting MOV to FLV?
FLV supports a limited set of codecs (such as H.264, VP6, MP3, AAC), so the MOV's streams are generally re-encoded to fit, which is lossy. The result will not exceed the source quality.
Why convert a MOV to FLV?
FLV was the dominant streaming video format of the 2000s, used by YouTube and most video sites of that era. You would convert to it for compatibility with legacy Flash-based players or tools that still expect .flv.
Can FLV be played now that Flash is gone?
Yes. An FLV is a linear video/audio stream, not interactive Flash, and the free VLC media player opens it on any platform without Flash. Flash's December 2020 end-of-life does not stop FLV playback.
Is FLV worth keeping long-term?
For durability, MP4 is the better choice - it plays almost everywhere, whereas FLV is a legacy container kept mainly for compatibility with older systems.
