About FLV

Flash Video

Adobe's container for Flash Player, which carried most web video in the late 2000s, usually with Sorenson Spark, VP6 or H.264 video. Flash Player was discontinued at the end of 2020. Convert FLV to MP4 to play saved Flash-era video now that Flash is gone.

About OPUS

Opus

An open, royalty-free lossy codec standardized by the IETF as RFC 6716 in 2012, built for speech and music at low bitrates. WebRTC calls and WhatsApp voice notes use it, usually inside an Ogg container. Use it for the smallest files at good quality for voice, podcasts or music, when the player supports it.
