What to expect

  • Video and audio are re-encoded into FLV's limited codec set, a lossy step usually at lower bitrate than the source.
  • Surround audio from Blu-ray is reduced to a simpler stereo track.
  • FLV is a frozen, Flash-era format; MP4 is the more compatible choice for current players.

Frequently asked questions

Will M2TS to FLV lose quality?
Yes, there is a lossy re-encode. The Blu-ray video is recompressed into an FLV-compatible codec such as H.264 or VP6, and FLV is typically used at lower bitrates, so fine detail can be reduced.
Why convert M2TS to FLV?
FLV was the standard video format for Flash Player and the streaming sites of the 2000s. Converting is useful for legacy systems or tools that still expect FLV; for modern playback, MP4 is the better target.
Does FLV still work after Flash's end-of-life?
Yes. FLV is plain video/audio data, not the interactive Flash plug-in, so VLC opens FLV files on any platform without Flash installed. Flash being discontinued does not stop FLV playback.
What gets dropped from the M2TS?
FLV's codec and audio options are narrower than Blu-ray's, so multichannel Dolby/DTS audio is reduced to MP3/AAC stereo and the high-resolution video is re-encoded. Subtitles and extra streams are generally not preserved.
