Generation loss — quality may degrade
FLV uses lossy compression, and so does M4A. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your FLV file may contain FLV metadata metadata. M4A has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
M4A lossy compression can produce pre-echo at low bitrates (AAC). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

En raison de l'omniprésence passée de Flash dans la diffusion de contenus multimédias en ligne (notamment pour les archives de chaînes de télévision ou de plateformes éducatives), de nombreux documents administratifs ou académiques francophones se retrouvent encore sous format FLV. La conversion en M4A est donc très pertinente pour leur pérennisation et accessibilité.
