WTV to 3GP Converter

How to Convert WTV to 3GP Online

1. Upload Your WTV File: Drag and drop or click "Add Files" to select WTV recordings exported from Windows Media Center, Xbox Recorded TV, or a Media Center Extender. Batch is supported — drop in a whole folder of TV captures and each file converts in parallel.
2. Pick Quality Preset or Bitrate Mode: Default is the "Very High (Recommended)" Quality Preset, which targets a clean H.264-in-3GP output sized for modern phones. Switch to Specific file size to cap output at an exact MB target (useful for MMS / WhatsApp / Discord caps), Constant Bitrate for predictable per-second sizing, Variable Bitrate for smaller files at the same perceived quality, or Constant Quality to fine-tune with a CRF slider (18 = visually lossless, 23 = balanced, 28 = noticeably smaller).
3. Resize, Trim, or Pick a Codec (Optional): Under Video resolution, keep original, pick a Preset Resolution (the 3GP spec was originally designed for 176×144 QCIF / 320×240 QVGA, but 3GP containers today routinely hold 480p, 720p, and 1080p), scale by Resolution Percentage, or enter Width × Height. Pick a 3GP-spec video codec — H.264 (best compatibility on modern handsets), MPEG-4 Part 2, H.263, or H.263+ for legacy GSM phones. Pick AMR-NB (4.75–12.2 kbps speech) or AMR-WB (6.6–23.85 kbps wideband) for low-bandwidth voice, or AAC for music and broadcast audio. Under Trim, select Time Range to cut out commercials before encoding.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no email required. Download individually or as a ZIP.

Why Convert WTV to 3GP?

WTV is Microsoft's broadcast-TV container, introduced with the Windows Media Center TV Pack 2008 and shipped on every Windows Vista Home Premium/Ultimate, Windows 7 (Home Premium and above), and Windows 8/8.1 Pro Media Center add-on. WTV files typically hold full ATSC/DVB transport-stream-grade MPEG-2 video at up to 30 Mbps with AC-3 5.1 or MPEG-1 Layer II audio, plus EPG metadata and CableCARD DRM flags. The format is large, Windows-only, and largely orphaned after Microsoft retired Windows Media Center in Windows 10 (announced May 2015). 3GP (3GPP TS 26.244, released 2003) is the polar opposite: a streamlined MP4-derived container designed by the 3rd Generation Partnership Project for GSM 3G mobile networks, sized for tiny phone screens, low-bandwidth MMS, and feature phones with limited codecs. Converting collapses a 5 GB recorded broadcast into a phone-friendly 50–200 MB clip. Common reasons:

• Sideload TV recordings onto legacy GSM phones — Nokia Symbian devices, BlackBerry, early Sony Ericsson Walkman phones, and most 2G/3G feature phones natively read 3GP but never knew what to do with WTV or MPEG-2. Re-encoding to H.263 + AMR-NB inside 3GP makes recordings playable directly from the SD card.
• MMS-size clips of short TV moments — Carriers historically cap MMS attachments at 300 KB–1 MB depending on operator and plan. With AMR-NB audio and 176×144 QCIF H.263 video, a 30-second clip fits well under that ceiling — exactly what 3GP was engineered for.
• Free up the 60–80 GB an hour of HD WTV consumes — A two-hour 1080i ATSC broadcast routinely lands at 12–18 GB in WTV. Converting to 480p H.264 inside 3GP for casual rewatching shrinks that to ~250 MB without dropping recognisable quality on a phone screen.
• Play on devices that never spoke MPEG-2 — Many older Android phones, JVC/Sony feature phones, and Java ME players support 3GP but not MPEG-2. WTV's reliance on MPEG-2 (and AC-3, which is licensed separately from Dolby) makes it stubbornly Windows-only.
• Strip DRM-free recordings out of a dead ecosystem — WTV's container format is opaque outside Windows Media Center; ffmpeg can read most non-protected WTV files, but the format is no longer maintained. Re-containerising into 3GP — which is ISO 14496-12 based, the same base format as MP4 — guarantees the file is readable in 2026 and beyond.
• Voice-only archive of news broadcasts or interviews — Pair AMR-WB (16 kHz wideband speech) with a tiny H.263 video track or no video at all to keep podcast-style copies of long broadcasts at ~1 MB per minute.

If your target device is from the last decade, Convert WTV to MP4 is usually the better choice — MP4 is now universal where 3GP used to live. 3GP makes sense specifically when you need 3GPP-mandated codecs or strict mobile compatibility.

Frequently Asked Questions

Will I lose quality converting WTV to 3GP?

Almost always yes, but intentionally. WTV typically holds full-broadcast MPEG-2 at 4–18 Mbps. 3GP was designed for mobile networks and rarely exceeds 500 kbps to a few Mbps even at H.264 settings. The conversion is lossy by design — that's the whole point of moving from broadcast to mobile. If you keep H.264 at the "Very High" preset and 480p resolution, the output will still look clean on any phone screen. If you must keep broadcast-grade quality, Convert WTV to MP4 instead and skip 3GP entirely.

Why is the audio so muffled after conversion?

Almost always because the output is using AMR-NB. AMR-NB is a 4.75–12.2 kbps narrowband speech codec running at an 8 kHz sample rate with a 300–3400 Hz speech-tuned bandwidth — it was built for cellular voice calls, not music or broadcast audio. Switch to AMR-WB (16 kHz, 50–7000 Hz, up to 23.85 kbps) for noticeably better speech, or AAC-LC at 96–128 kbps if you need music or general broadcast audio inside the 3GP container.

What's the difference between 3GP and 3G2?

3GP (TS 26.244) targets GSM-based UMTS networks; 3G2 (3GPP2 C.S0050) targets CDMA2000-based networks (historically Verizon, Sprint, KDDI au). Both use the same ISO base media file format, but 3G2 adds CDMA-specific audio codecs (EVRC, QCELP, SMV, VMR-WB) and drops AMR-WB+ and Enhanced aacPlus support. If you don't know which to pick, 3GP is the safer default for the vast majority of phones outside CDMA carriers. Use Convert WTV to 3G2 if you specifically need CDMA codecs.

Will the output play on a modern iPhone or Android phone?

Yes, with caveats. Modern iOS plays 3GP through Safari and QuickTime; modern Android plays 3GP natively (it's still in AOSP MediaCodec). However, native players sometimes refuse exotic 3GP profiles. If broad modern-device compatibility matters more than legacy-phone compatibility, Convert WTV to MP4 is the safer call. Use 3GP when the target is specifically an old or feature-phone-era device.

Can I cut commercials out before converting?

Yes. Under Trim, select Time Range and enter a start time and duration in seconds or HH:MM:SS.sss format. Trimming runs before the encode, so the converter only re-encodes the kept segments — significantly faster than encoding the full TV broadcast first. For more complex multi-segment cuts (e.g., trim each commercial break separately), Video Cutter handles split-and-rejoin workflows.

Why is my output file so much smaller than the WTV source?

That's the conversion working as intended. WTV broadcasts typically run 4–18 Mbps because they're carrying ATSC/DVB transport streams encoded for living-room screens. 3GP at H.264 480p around 600 kbps gives a perfectly watchable phone-screen clip at a fraction of the bitrate — so a 6 GB WTV recording often becomes a 200–400 MB 3GP file. If the result looks too compressed for your taste, raise the Quality Preset or switch to a higher Constant Bitrate value.

Can XConvert read DRM-protected WTV recordings?

No, and neither can any general-purpose tool. CableCARD broadcasts and channels flagged with the broadcast-flag DRM bit are encrypted and tied to the original recording PC. The encryption key is bound to the Windows Media Center machine that recorded the file, so the encrypted body of the file is unreadable elsewhere. Over-the-air ATSC recordings without the broadcast flag (which is the default for most US OTA stations) convert without issue.

What's the file size limit?

XConvert handles multi-GB WTV recordings, including full-length 1080i broadcasts. Conversion happens in your browser, so the practical limit is your device's available RAM and patience for the upload. There's no fixed per-file cap and no quantity limit on batch jobs. Tip: trim out the parts you don't need first (Step 3) to reduce both upload time and encode time.

Can I batch-convert a whole folder of recorded shows?

Yes. Drop the entire folder in — every WTV file enqueues with the same settings, runs in parallel within your browser session, and downloads individually or as a single ZIP. You can also override settings per file if some are music broadcasts (AAC-LC audio) and some are news (AMR-WB audio).
