\Users\Public\Recorded TV\ folder (or wherever Windows Media Center wrote them). Batch upload works — queue an entire season of recordings in one pass. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.WTV is a Microsoft-only container — it was introduced as part of the Windows Media Center TV Pack 2008 for Vista and became standard in all Windows 7 Media Center editions. Microsoft then discontinued Windows Media Center in Windows 10 in October 2015, leaving an entire generation of recorded TV stranded in a format that nothing outside Media Center plays cleanly. MTS (the AVCHD transport stream developed by Sony and Panasonic in 2006) is the import format every consumer camcorder workflow already understands, which makes it the natural target when you want broadcast recordings to live alongside camcorder footage in a single edit project.
Working with multiple recordings? After conversion, trim MTS to cut commercials precisely, compress MTS to shrink for archival, or push further to MP4 or MOV for phone-friendly delivery. Going the other direction? See MTS to WTV.
| Property | WTV (Windows Recorded TV) | MTS (AVCHD) |
|---|---|---|
| Developed by | Microsoft (Windows Media Center) | Sony + Panasonic |
| First shipped | TV Pack 2008 for Vista; standard in Windows 7 | 2006 (AVCHD spec) |
| Container | Proprietary Microsoft container (not ASF-based; succeeded.dvr-ms) | MPEG-2 transport stream |
| Video codec | MPEG-2 primarily, can also wrap H.264 broadcast streams | H.264 / MPEG-4 AVC |
| Audio codec | MPEG-1 Layer II or Dolby Digital AC-3 (ATSC A/52) | Dolby AC-3 64-640 kbit/s, or linear PCM |
| Typical source | Live TV recorded via a Windows Media Center TV tuner card | Consumer HD camcorders (Sony Handycam, Panasonic HDC, Canon HF) |
| Max video bitrate | Up to ~30 Mbps via the Stream Buffer Engine | 24 Mbps on flash media; 28 Mbps for 1080p50/60 |
| DRM | CGMS-A copy-protection flag; protected recordings only play on the recording PC | None in the spec |
| Native playback | Windows Media Center only (discontinued in Windows 10, Oct 2015) | VLC, MPC-HC, IINA, mpv, every NLE, every AVCHD camcorder app |
| Metadata | EPG data, channel info, recording timestamps, captions | AVCHD index files (.cpi,.bdm) when on camcorder media |
These ranges match what consumer camcorders and AVCHD authoring tools expect. Pick from this table when you switch to Constant Bitrate or Variable Bitrate in Step 2.
| Source | Recommended bitrate | Notes |
|---|---|---|
| 1080p60 / 1080p50 (sports, action TV) | 24-28 Mbps | Top of the AVCHD spec; preserves motion clarity |
| 1080i60 / 1080i50 (broadcast HD) | 17-24 Mbps | Standard AVCHD ceiling; transparent for most broadcast sources |
| 1080p30 / 1080p24 (drama, film transfers) | 12-18 Mbps | Lower motion budget; 18 Mbps is the AVCHD-on-DVD ceiling |
| 720p60 (sports SD upscale) | 10-15 Mbps | Comfortable headroom for H.264 at 720p |
| 720p30 / 720p24 | 6-10 Mbps | Standard YouTube-style target |
| 480p / DVD-grade SD | 4-8 Mbps | Use the lower end when the source is already SD broadcast |
No browser-based converter can. Windows Media Center reads the broadcaster's CGMS-A copy-protection flag and, when set, encrypts the audio and video elementary streams so the recording only plays on the PC that captured it. This is enforced at the file level, not by the player, so xconvert, HandBrake, ffmpeg, and every other converter will see encrypted streams. If the recording is from a free over-the-air U.S. broadcast (most cable systems also mark them "Copy Freely"), it will not be flagged and will convert normally. Encrypted recordings have to be decrypted on the original Media Center PC before any conversion will work.
Yes. WTV most commonly carries Dolby Digital AC-3 audio (the same codec AVCHD uses), so when xconvert re-wraps to MTS the audio passes through into an AVCHD-spec stream. If your WTV used MPEG-1 Layer II audio (older or international ATSC sources), it is transcoded to AC-3 to stay within the AVCHD specification — MTS players expect AC-3 or LPCM, not MPEG-1 Layer II.
Keep H.264 video below 24 Mbps for standard AVCHD targets and below 28 Mbps if you specifically need 1080p50/60. AC-3 audio is defined between 64 and 640 kbit/s — 256 kbit/s stereo or 384 kbit/s 5.1 are typical. Going above 24 Mbps video produces a file that still plays in VLC and NLEs but may be rejected by stricter AVCHD-disc authoring tools and some camcorder playback firmware.
Because WTV often stores broadcast MPEG-2 at modest cable/OTA bitrates (typically 12-19 Mbps for U.S. HD broadcasts), and the converter is re-encoding to H.264 at a quality preset that may use more bits than the source if you picked "Very High." Pick Constant Bitrate with a target near the original (run MediaInfo on the WTV to read its overall bitrate) or use Specific file size to cap the output.
Yes — those are WTV-container metadata and have no equivalent slot in the AVCHD/MTS transport stream. Closed-caption text, electronic program guide entries, the recording start/end timestamps, and broadcaster channel info are dropped in the conversion. Convert to MKV instead if preserving captions matters; MKV has dedicated subtitle and metadata tracks.
VLC can play many WTV files but stumbles on the proprietary index and on any DRM-flagged streams. HandBrake historically refused WTV outright; recent builds accept WTV via the LibAV reader but still trip on encrypted recordings. Browser-based conversion sidesteps the install-and-troubleshoot dance, especially on Mac or Linux machines that never had Media Center.
Both are AVCHD transport streams with the same internal bytes — only the extension differs. AVCHD camcorders write the file as .mts on the SD card or internal flash; when you import the clips into Sony PMB / PlayMemories Home or Panasonic HD Writer, the desktop app renames them to .m2ts. Any tool that reads one reads the other. xconvert outputs .mts for camcorder-native compatibility; see MTS to M2TS if your NLE specifically expects the .m2ts extension.
No. xconvert runs entirely on our servers and does not depend on the Microsoft DirectShow filters that WMC installed. You can convert WTV files on macOS, Linux, ChromeOS, or any Windows 10/11 machine where Media Center was never present — provided the recordings themselves aren't DRM-encrypted (see the first question).
Live broadcast WTV is usually 1080i60 or 480i60 (interlaced), and AVCHD MTS supports both interlaced and progressive video. The xconvert pipeline preserves the source field structure by default. If you want progressive output for modern displays, pick a progressive Preset Resolution (1080p, 720p) — the encoder will deinterlace as it scales. For frame-accurate cuts on broadcast content, trim the MTS after conversion rather than before.
