WTV (Windows TV) is Microsoft's DVR recording format introduced with Windows Media Center in Windows Vista (2007), replacing the older DVR-MS format. WTV files contain MPEG-2 or H.264 video with AC3 or AAC audio, plus rich EPG metadata including program title, description, channel name, recording time, and content ratings. The format uses an NTFS-like internal structure with multiple multiplexed streams. 3GP is the 3GPP mobile multimedia container designed for feature phones and low-bandwidth cellular networks.
Since Windows Media Center was discontinued after Windows 10 — Microsoft removed it entirely — WTV is a legacy format with no active software creating new files. However, millions of recorded TV files still exist in personal archives from the Windows Media Center era, spanning nearly a decade of home TV recording.
WTV files are effectively unplayable outside of Windows, and even on modern Windows 10/11 systems, native WTV support has been removed along with Windows Media Center. Most media players, mobile devices, and streaming platforms cannot open WTV files at all, leaving years of recorded television trapped in an obsolete format.
Converting WTV to 3GP makes TV recordings accessible on the most basic mobile devices and feature phones. While 3GP is a heavily compressed format, it enables sharing short clips from recorded TV shows via MMS or viewing highlights on budget hardware where bandwidth and storage are limited.
FFmpeg demuxes the WTV container, extracting the MPEG-2 or H.264 video stream and the AC3 or AAC audio track. The video is re-encoded to H.263 or MPEG-4 Simple Profile at QCIF (176x144) or CIF (352x288) resolution. Audio is decoded and re-encoded to AMR-NB at 8 kHz mono. EPG metadata (program title, channel, recording time, ratings) is discarded since 3GP has no equivalent metadata fields. For interlaced 1080i WTV sources, the yadif deinterlace filter is applied before downscaling.
WTV recordings are typically standard definition (480i NTSC or 576i PAL for over-the-air MPEG-2) or high definition (720p or 1080i for cable/satellite H.264). Files range from 1 to 8 GB per hour depending on source quality. Converting to 3GP dramatically reduces resolution and bitrate — a 4 GB one-hour HD recording may compress to 10-30 MB. The result is watchable on small mobile screens but loses all fine detail. Interlaced 1080i content requires deinterlacing before the resolution downscale.

WTV to 3GP conversion rescues Windows Media Center TV recordings from format obsolescence and compresses them into the most compact mobile format for feature phone viewing and MMS sharing.
