FLV and FLAC explained
What is a FLV file?
FLV (Flash Video) was the standard for online video during the Flash era. Since Flash is gone, converting FLV to MP4 keeps old videos playable on modern devices.
What is a FLAC file?
FLAC is a lossless audio format that compresses sound without throwing away any data. It keeps perfect CD quality while using about half the space of WAV, which makes it a favorite among audiophiles.
