About WTV to Mobile Video Conversion
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 EPG metadata. The Mobile Video device preset is a universal mobile profile that produces H.264 Baseline video with AAC-LC audio at 480p resolution — designed to play on any mobile device regardless of manufacturer, operating system, or hardware generation.
Unlike platform-specific presets (Android, iPhone, Kindle), the Mobile Video preset targets the lowest common denominator of mobile playback. This makes it the safest choice when the target device is unknown, when sharing with people who have different phones, or when compatibility across a wide range of devices is more important than maximum quality.
Why Convert WTV to Mobile Video?
WTV files are unplayable on every mobile platform. The Mobile Video preset produces the most broadly compatible mobile output possible — H.264 Baseline Profile at 480p with AAC stereo. This combination plays on Android phones, iPhones, Windows phones, feature phones with video capability, cheap tablets, portable media players, and virtually any device with a screen and a video decoder.
The 480p resolution is deliberate: it ensures smooth playback on low-end hardware while producing small files that transfer quickly over Bluetooth, USB, or slow internet connections. For TV recordings that will be shared among multiple people with different devices, this universal compatibility avoids format headaches entirely.
Common Use Cases
- Converting TV recordings for sharing with friends and family who have various phone brands and models
- Producing universally compatible mobile video from WTV archives for broad distribution
- Creating lightweight video files from WTV recordings for transfer over slow connections or Bluetooth
- Building a portable TV library that plays on any device without format troubleshooting
- Preparing WTV content for playback on legacy media players, car infotainment screens, and portable devices
How It Works
FFmpeg demuxes the WTV container and encodes using the most compatible mobile profile. The preset outputs H.264 Baseline Profile Level 3.0 at 480p (854x480 or 640x480) with AAC-LC mono or stereo at 96-128 kbps. Video bitrate targets 1-2 Mbps. Interlaced WTV sources are deinterlaced with yadif. AC3 5.1 audio is downmixed to stereo or mono. Frame rate is capped at 30 fps. The MP4 container includes faststart for streaming compatibility.
Quality & Performance
The Mobile preset prioritizes compatibility over quality. At 480p with 1-2 Mbps H.264, the output is clean and watchable on screens up to 5-6 inches but lacks the sharpness of 720p or 1080p presets on larger screens. Audio at 96-128 kbps AAC is adequate for speech and music through phone speakers or earbuds. File sizes are compact at 0.5-1 GB per hour.

Tips for Best Results
- 1Choose the Mobile preset when you do not know the target device or need to share with multiple people on different platforms
- 2Use 480p to keep file sizes under 1 GB per hour for devices with 16-32 GB storage
- 3The Mobile preset works well for car USB ports and portable media players in addition to phones
- 4For better quality on known modern devices, switch to the Android or iPhone preset instead
- 5Trim recordings before conversion — commercial-free clips are smaller and more pleasant to watch on mobile
