The iPhone Video preset creates H.264 MP4 files specifically optimized for iPhone's hardware video decoder and display characteristics. RMVB's RealVideo codecs are completely unsupported by iOS — the iPhone has never included a RealMedia decoder in its media framework. For the large number of users in China and Southeast Asia with RMVB collections, this conversion is the only way to watch that content natively on iPhone.
iPhone cannot decode RMVB at all through native APIs. While VLC for iOS can software-decode RMVB, it's inefficient, drains battery rapidly, and may stutter on complex scenes. Converting to the iPhone Video preset uses the dedicated H.264 hardware decoder for smooth, power-efficient playback with proper iOS integration (AirPlay, PiP, share sheet).
FFmpeg decodes RealVideo 8/9/10 streams and RealAudio, then encodes to H.264 Main Profile Level 3.1 with CRF 23 and AAC-LC at 128 kbps stereo. Resolution from RMVB sources is maintained at native size or scaled to 1920x1080 maximum. The MP4 container uses faststart for progressive playback.
Quality typically improves over the RMVB source. H.264 Main Profile at CRF 23 is more efficient than RealVideo 9/10, producing cleaner video at comparable bitrates. On iPhone's smaller screen, the quality difference from the original RMVB is even less noticeable.
