About Flash Video (FLV)
Flash Video (FLV) is the container Adobe Flash Player used to stream video on the web, typically with H.264 or the older Sorenson Spark and VP6 codecs.
Videos saved from websites of the Flash era and from some older streaming and recording tools.
Adobe ended Flash Player at the end of 2020 and browsers removed it, so FLV files need a converter or a desktop player such as VLC.

Why won't my old FLV videos play anywhere anymore? Flash Player was retired at the end of 2020 and browsers dropped support, so the only practical way to keep them is converting to MP4.
About M4A (AAC/ALAC)
M4A is an MPEG-4 audio file: the MP4 container holding only audio, usually AAC and sometimes Apple Lossless (ALAC).
Music bought on iTunes, iPhone voice memos and many podcast downloads.
Whether an M4A is lossy or lossless depends on the codec inside, which the file extension does not show.
Why convert audio to M4A? It wraps efficient AAC audio with chapter marks and cover art in one small file that Apple, Android and Windows all play.
What changes when you convert FLV to M4A
- The soundtrack of the FLV is re-encoded as M4A at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the M4A file contains the audio track of your FLV, and the picture is dropped.
