Most WEBM to FLV conversions are wrapper swaps: the pictures stay pictures, they just trade WEBM's box for one built for nothing new: today it's mostly old downloads waiting to be rescued. If the codec inside your WEBM is one FLV accepts, Flippy keeps quality bit-for-bit identical; if not, it re-encodes once, carefully, at matching quality.

Why flip WEBM to FLV

WEBM is video the way browsers like it: open, royalty-free and built to stream. It was born in 2010, Google, out of its VP8 acquisition, and its real weak spot is life outside the browser: editors, TVs and Apple devices get picky.

FLV is a relic of the Flash era: the format YouTube grew up on, stranded when Flash died. The Flash Video container, typically holding old H.263, VP6 or early H.264 streams. That makes it the right destination when what you need is nothing new: today it's mostly old downloads waiting to be rescued.

Questions people ask

Will converting WEBM to FLV lose quality?

Usually not: when the video codec is compatible, Flippy swaps the container without re-encoding, so quality is untouched. If a re-encode is needed, it happens once at matching quality.

Will the FLV file be bigger or smaller than my WEBM?

Similar, unless a re-encode is involved: then it depends on the codec. FLV typically runs small files with dial-up-era expectations about quality.

Where will the FLV file play?

Almost nothing modern; VLC and converters are its retirement home. That's the usual reason people leave WEBM behind: FLV simply opens in more of the places that matter.

How long does WEBM to FLV conversion take?

When it's a pure container swap it's nearly instant, since nothing is re-encoded. Full re-encodes take roughly as long as the video plays, often less.
