Supports: WTV
C:\Users\Public\Recorded TV on Windows 7 Media Center). Batch is supported — drop in an entire season of recordings and each file is processed in parallel.WTV (Windows Recorded TV Show) is the recording container Microsoft introduced with the Windows Media Center TV Pack 2008 for Windows Vista, then carried into Windows 7. It replaced the older DVR-MS format and — contrary to common confusion — does not use ASF as the underlying container (DVR-MS does; WTV uses a Microsoft-proprietary structure). WTV typically wraps MPEG-2 video plus MPEG-1 Layer II or Dolby Digital AC-3 audio for SD broadcasts, or H.264 for HD ATSC recordings. MPEG-2 (ISO/IEC 13818-2, also published as ITU-T H.262) is the elementary-stream video standard behind DVD-Video, ATSC over-the-air broadcasting, and DVB satellite/cable. Common reasons to convert:
-c:v copy -c:a copy. No re-encoding, no quality loss. HD ATSC recordings that wrap H.264 do require a transcode.| Property | WTV | MPEG-2 (.mpeg2 /.mpg) |
|---|---|---|
| Type | Container (Microsoft proprietary; not ASF) | Video standard (ISO/IEC 13818-2 / ITU-T H.262) — used as elementary stream or wrapped in MPEG program/transport stream |
| Standardized | Introduced with Windows Media Center TV Pack 2008 (Vista); standard in Windows 7 Media Center | First published 1996; latest edition 2013 |
| Video codecs inside | MPEG-2 (SD broadcasts), MPEG-4 / H.264 (HD ATSC tuner recordings) | MPEG-2 only |
| Audio codecs | MPEG-1 Layer II, Dolby Digital AC-3 | Pairs with MPEG-1 Layer II, AC-3, or PCM in container; not a container itself |
| Native playback | Windows Media Center (Windows 7), Films & TV (with codec pack), a handful of third-party tools | DVD players, VLC, MPV, QuickTime (with codec), every modern NLE, set-top boxes |
| Typical bitrate | 6-19 Mbit/s depending on tuner | DVD-Video peak 9.8 Mbit/s video / 10.08 Mbit/s total; ATSC 19.39 Mbit/s broadcast |
| Editing | Awkward — most editors want DVR-MS or transcoded MPEG-2 first | Direct edit in any major NLE; cuts on GOP boundaries |
| Best for | Recording TV on Windows Media Center | DVD authoring, broadcast/archive workflows, NLE ingest |
| Mode | What it does | Pick when |
|---|---|---|
| Quality Preset | One-click Highest → Lowest preset (default Very High) | You want a sensible default with no tweaking |
| Specific file size | Auto-tunes bitrate to hit an exact MB target | You're sizing for a DVD-5 (4.7 GB) or DVD-9 (8.5 GB) burn |
| Constant Bitrate (CBR) | Fixed bits per second across the entire video | Broadcast-style streams, predictable sizing, DVD compliance |
| Variable Bitrate (VBR) | Spends more bits on complex scenes, fewer on simple | Best quality-per-MB for archive |
| Constant Quality | qscale-based (1-31 for MPEG-2; 1 = best, 31 = worst) | Consistent perceived quality across episodes of varying complexity |
| Constraint Quality | VBR with a ceiling bitrate | Keeping output below the DVD-Video 9.8 Mbit/s video cap |
| Bitrate | Size per hour | Resolution sweet spot | Best for |
|---|---|---|---|
| 9.8 Mbit/s | ~4.4 GB | 720×480 NTSC / 720×576 PAL | DVD-Video peak — maximum the spec allows |
| 6 Mbit/s | ~2.7 GB | 720×480 / 720×576 | Standard DVD-Video target — fits ~2 hours on a DVD-5 |
| 4 Mbit/s | ~1.8 GB | 720×480 / 720×576 | Long-play DVD (3+ hours per DVD-5) |
| 19.39 Mbit/s | ~8.7 GB | 1920×1080i / 1280×720p | ATSC broadcast maximum |
| 15 Mbit/s | ~6.75 GB | 1080i | High-quality HDTV archive |
| 8 Mbit/s | ~3.6 GB | 720p | Compact HDTV archive |
If your WTV source already contains MPEG-2 video (true for SD ATSC, DVB, and most analogue-tuner recordings on Windows Media Center), the conversion is essentially a remux — the elementary MPEG-2 video stream and AC-3 or MP2 audio stream move into the new container with no re-encoding and zero quality loss. This is the same operation FFmpeg performs with -c:v copy -c:a copy. If your WTV holds H.264 video (HD ATSC tuner recordings), MPEG-2 output requires a transcode; pick Very High preset or qscale 2-3 to stay visually transparent.
Windows Media Center's default save location is C:\Users\Public\Recorded TV (Windows 7) or C:\Users\Public\Public Recorded TV. You can change the path inside Media Center under Tasks → Settings → TV → Recorder → Recorder Storage. Files have the.wtv extension and a "Windows Recorded TV Show" type in Explorer. Drop them directly onto this tool — no need to convert through Microsoft's WTVconverter.exe first.
Most NLEs don't ship a WTV demuxer. Premiere and Resolve in particular treat WTV as an unsupported container even when the inner MPEG-2 stream is standard. Converting to MPEG-2 (.mpg program stream or.mpeg2 elementary stream) gives the NLE a format it understands directly, and on MPEG-2 sources the conversion is lossless because it's a container swap rather than a re-encode.
The MPEG-2 elementary stream we produce is DVD-compliant when you stay under 9.8 Mbit/s video / 10.08 Mbit/s total bitrate at 720×480 (NTSC) or 720×576 (PAL). To burn a playable DVD you still need an authoring tool — DVDStyler (free, cross-platform), ImgBurn (Windows, free), or Nero — that builds the VIDEO_TS folder structure with IFO/BUP files. The Specific file size mode is useful for sizing 2 hours of video to fit a 4.7 GB DVD-5 budget.
.mpeg2 and .m2v are extensions for raw MPEG-2 video elementary streams — video only, no audio multiplexed in. .mpg (and .mpeg) typically denote MPEG-1/MPEG-2 program streams that wrap both video and audio (and optionally subtitles) into a single file ready for playback or DVD authoring. If you need video+audio playback in one file, see WTV to MPG or WTV to MPEG. Pick.mpeg2 here when you need video-only for NLE ingest or muxing later.
Yes. Use the Trim section, pick Time Range, and enter start time + duration. Both accept seconds (135.5) or HH:MM:SS.sss format (00:02:15.500). For multi-cut commercial removal across one file (typical for TV recordings), use Trim WTV first to produce a clean source, then convert to MPEG-2 — that keeps the heavy bitrate budget for the program content rather than ads you'll strip anyway.
HD ATSC tuner recordings typically use H.264 video at 8-15 Mbit/s. Re-encoding to MPEG-2 at visually similar quality usually needs 12-20 Mbit/s because MPEG-2 is a 1996-era codec with weaker compression — roughly 2× the bitrate for equivalent perceived quality. If size matters more than format compliance, consider WTV to MP4 (keeps H.264 stream-copy, much smaller files) instead of MPEG-2 unless you specifically need DVD/broadcast compatibility.
No — this is a common confusion. The older DVR-MS format (Windows XP Media Center) does use ASF as its container. WTV (Windows 7 / Vista Media Center TV Pack 2008 onward) replaced DVR-MS with a different Microsoft-proprietary structure and does not use ASF. WMV uses ASF and the WMV codec, but that's a separate format from WTV.
Yes — see MPEG-2 to WTV for the reverse direction (useful for re-importing edited recordings back into Windows Media Center). If you only want to shrink a WTV recording without changing format, use Compress WTV.
