WTV (Windows TV) is Microsoft's DVR recording format from Windows Media Center, storing broadcast television with MPEG-2 or H.264 video, AC3 or AAC audio, and rich EPG metadata. The iPhone Video device preset is a pre-configured FFmpeg profile producing H.264 Main Profile video with AAC-LC audio, optimized for iPhone hardware video decoding at resolutions up to 1080p with bitrates balanced for quality and storage efficiency on mobile.
The iPhone has been the world's most popular smartphone for media consumption, with hardware video decoding that handles H.264 at up to 4K resolution. The iPhone preset targets the sweet spot of 720p-1080p where quality is excellent on the 6.1-6.7 inch display without wasting storage on resolution the small screen cannot fully utilize.
iOS has never supported WTV playback and never will — the format is entirely Microsoft-specific. Converting WTV recordings to the iPhone preset produces MP4 files that play natively in the iPhone's Videos app, Files app, and any third-party player. The preset handles broadcast-specific challenges like deinterlacing 1080i content and downmixing multichannel AC3 to stereo automatically.
The iPhone preset balances quality against the practical limits of phone viewing. On a 6.1-inch screen, 720p and 1080p are nearly indistinguishable, so bitrates are optimized for efficient storage rather than maximum resolution. This means more hours of TV recordings fit on the device for extended trips and commutes.
FFmpeg demuxes the WTV container and applies the iPhone-optimized encoding profile. The preset uses H.264 Main Profile Level 3.1 at up to 720p or 1080p resolution, depending on source quality. Audio is encoded as AAC-LC stereo at 128 kbps. Interlaced WTV sources are deinterlaced with yadif. AC3 5.1 surround audio is downmixed to stereo for headphone and speaker playback. The MP4 container uses faststart for instant playback. Target video bitrate is 2-4 Mbps.
At 720p with 2-4 Mbps H.264, the iPhone preset delivers excellent visual quality that fully utilizes the iPhone's display. Text overlays, scoreboards, and fine details in broadcast content remain sharp and readable. AAC at 128 kbps is transparent for broadcast audio through AirPods or iPhone speakers. File sizes average 1-1.5 GB per hour, allowing 20+ hours of TV on a 64 GB iPhone.
