Some metadata may not survive
Your MOV file may contain QuickTime atoms, chapter markers metadata. FLAC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Default format on iPhone
Your device saves files in MOV by default (iPhone, iPad, Mac cameras). Most people convert because the files won't open on other devices — FLAC is universally supported and will work everywhere.
