What to expect

Frequently asked questions
What happens to quality converting `MTS` to `FLV`?
FLV can carry H.264 video like the source, but its audio is re-encoded (FLV uses MP3 or AAC), so expect a lossy audio pass and possible video re-encoding depending on the settings used.
Why would I convert MTS to FLV?
FLV was the standard container for web streaming through the 2000s, so conversion is usually for compatibility with older Flash-based players or legacy video pipelines that expect it.
Where does an FLV file open today?
FLV opens in VLC on any platform without Flash; on the modern web, though, MP4 has largely replaced it, so FLV is mainly useful for legacy systems.
What limitations affect HD AVCHD in FLV?
FLV originated in a lower-bitrate streaming era, so high-bitrate HD AVCHD footage may be down-converted, and camcorder metadata does not carry into the FLV container.
