Convert MTS to FLV — Free Online Converter

MTS/AVCHD camcorder recordings store full HD video in a format designed for disc playback and camera storage, not for internet delivery. FLV (Flash Video) was the dominant web video format from 2005 to 2015, and its underlying RTMP streaming protocol still powers live streaming infrastructure for Twitch, YouTube Live, and Facebook Live. Converting MTS to FLV repackages camcorder footage for RTMP-based streaming and legacy Flash web systems.

RTMP (Real-Time Messaging Protocol) remains the industry standard for live stream ingestion. OBS Studio, Streamlabs, and professional broadcast encoders all push video to streaming platforms as FLV over RTMP. If you need to feed pre-recorded camcorder footage into an RTMP server — for rebroadcasting recorded events, scheduled programming, or testing — FLV is the required format.

Additionally, some legacy content management systems, e-learning platforms, and digital signage systems built during the Flash era still require FLV input. Converting AVCHD recordings to FLV with modern H.264 encoding ensures compatibility with these systems while maintaining good visual quality.
