.m1v extension. Converting is also useful when the audio track is not needed, because M1V stores video only.
What the WTV format is
WTV is the Windows TV Recording container used mainly by Windows Media Center in Windows Vista, Windows 7, and compatible later systems. It stores recorded television content along with video, audio, subtitles, metadata, and sometimes multiple program streams. WTV files may contain MPEG-2 or H.264 video, depending on the broadcast and recording setup. Copy-protected recordings may be encrypted and cannot be converted unless the source system permits playback and export.
What the M1V format is
M1V is an MPEG-1 Video elementary stream. It contains encoded video without an audio stream, subtitles, container metadata, or usually a program timeline. Its simple structure is accepted by some legacy MPEG-1 players, authoring applications, and hardware devices. MPEG-1 is less efficient than newer codecs, so converting to M1V can reduce compatibility problems but may increase file size at comparable visual quality.
How to convert WTV to M1V
For a browser-based conversion, use the converter on 101convert.com:
- Open the Video converter and select WTV to M1V.
- Upload the WTV recording.
- Start the conversion and download the resulting
.m1vfile when processing finishes.
This option requires no installed software. Large recordings can take longer to upload and process, and protected WTV files may be rejected or produce no usable output.
FFmpeg provides a local conversion method when the recording is not protected and FFmpeg can decode its streams. Run:
ffmpeg -i input.wtv -map 0:v:0 -an -c:v mpeg1video -q:v 2 -f mpeg1video output.m1v-map 0:v:0 selects the first video stream, -an discards audio, and -f mpeg1video writes a raw MPEG-1 video stream rather than an MPEG program stream. Replace input.wtv with the actual filename. Lower quality values generally produce better video and larger files; use a value such as -q:v 4 or -q:v 6 when size matters more than quality.
Quality and compatibility limitations
The conversion requires re-encoding when the WTV video is MPEG-2 or H.264, so some quality loss is unavoidable. M1V has no audio track; retain the original WTV if the recording's sound is needed, or create a separate compatible audio file and author both streams in an application that supports them. FFmpeg may preserve the source frame rate and dimensions, but an older target device may require MPEG-1-compatible resolutions such as 352×240, 352×288, 640×480, or 720×576. Check the generated file with an MPEG-1-capable player because some applications expect an MPEG program stream such as .mpg rather than a video-only .m1v file.
