Tietoa muunnoksesta MOV–FLV

FLV (Flash Video) was the dominant web video format from 2005-2012, powering early YouTube, Vimeo, and countless Flash-based video players. It uses the Sorenson Spark (H.263) or VP6 video codec with MP3 or AAC audio inside Adobe's proprietary container. While Flash Player was officially discontinued in 2020, FLV files remain common in legacy content management systems and older web platforms that haven't been updated.

Miksi muuntaa MOV muotoon FLV?

Converting QT to FLV is primarily needed for legacy system compatibility. Some older CMS platforms, e-learning systems, and enterprise intranets still use Flash-based video players that only accept FLV input. The format is also used in certain Chinese video platforms and archival systems where upgrading infrastructure is impractical.

Näin se toimii

FFmpeg converts the QT video stream to H.264 (or VP6 for maximum Flash compatibility) and audio to AAC or MP3. The output is muxed into the FLV container with proper FLV tag headers and timestamps. H.264 in FLV is supported by Flash Player 9.0.115+ but not by all standalone FLV players.

Laatu ja suorituskyky

FLV with H.264 video and AAC audio matches the quality of any other H.264 container at equivalent bitrates. VP6 or Sorenson Spark codecs produce noticeably lower quality but ensure compatibility with very old Flash Player versions. Typical web quality targets are 500-2000 kbps video bitrate.

Vinkkejä parhaisiin tuloksiin

1Use H.264 Baseline Profile with AAC audio for the best FLV quality — only fall back to VP6/Sorenson if targeting very old Flash Player versions.
2Set keyframe interval to 2 seconds for smooth seeking in Flash-based players, which rely on keyframes for seek points.
3If your legacy platform supports it, deliver MP4 via a JavaScript player (like Video.js) instead of FLV — it's a better long-term path.
4Keep FLV files under 100 MB for reliable upload to most legacy CMS platforms, which were designed for smaller web videos.

QT to FLV conversion serves niche legacy needs where Flash-era infrastructure persists. For any new project, MP4 or WebM are strongly preferred. Use this conversion only when your delivery system specifically requires FLV input.

Usein kysytyt kysymykset

No — Flash was discontinued in 2020 and FLV offers no advantages over MP4 or WebM. Only convert to FLV if your delivery platform specifically requires it.

No — browsers removed Flash Player support entirely by 2021. FLV playback requires a standalone player like VLC, PotPlayer, or a JavaScript-based FLV player library.

H.264 offers the best quality but requires Flash Player 9.0.115+. VP6 has broader legacy compatibility. Sorenson Spark (H.263) works with the oldest Flash Player versions but looks significantly worse.

FLV has no hard resolution limit, but content was traditionally encoded at 320x240 to 1280x720. Higher resolutions work with H.264 but may not play smoothly on legacy Flash-based players.

FLV supports basic text metadata but not standard subtitle tracks. Subtitles must be burned into the video during conversion.
