FLV (Flash Video) was designed for desktop web browsers running the Flash Player plugin — it was never intended for mobile playback. Mobile Video conversion produces an MP4 file with conservative H.264 encoding (Baseline Profile, Level 3.0) and AAC-LC audio, targeting the broadest possible mobile device compatibility. This covers Android phones, iPhones, Windows phones, basic feature phones, and portable media players manufactured in the last decade.
Mobile devices have diverse hardware capabilities — from flagship smartphones to budget feature phones. A universally compatible mobile video format must use the lowest common denominator of codec profiles. FLV's Sorenson Spark and VP6 codecs are not supported by any mobile hardware decoder. Converting to Mobile Video ensures playback on any phone or tablet regardless of manufacturer, operating system, or age.
FFmpeg encodes to H.264 Baseline Profile Level 3.0 — the most widely supported mobile video profile. Maximum resolution is 720p (1280x720) at 30 fps to ensure smooth decoding on low-power processors. Audio is AAC-LC at 96-128 kbps mono or stereo. The output bitrate is typically 800-1500 kbps to balance quality and file size for mobile data. Faststart is enabled for progressive download playback.
At 720p with 1-1.5 Mbps bitrate, the output looks sharp and smooth on phone screens up to 6 inches. The quality is well-matched to typical viewing conditions — held at arm's length, a phone screen does not reveal the subtle detail loss that would be visible on a desktop monitor. For most FLV source material (typically 480p or lower), the conversion maintains full source quality.
