About HEVC and FLV
HEVC: HEVC (H.265) halves file size compared to H.264 and is used by modern iPhones and 4K cameras, but many PCs, browsers and older phones cannot play it.
FLV: FLV is the Flash Video format that powered early YouTube. Flash is gone, so FLV files usually need converting to play today.
