WEBM to WMV Converter

Kept

• VP8 and VP9 video with Opus or Vorbis audio is read
• Windows Media Video 8 (WMV2) with Windows Media audio, which plays in Windows Media Player and old Windows software
• The original resolution and frame rate are kept
• A phone video recorded sideways or upside down is turned the right way up

Good to know

• WMV2 is an old codec: the quality is lower than H.264 at the same size, and the file is larger than an MP4 of the same clip.
• Audio is stereo.
• The video is re-encoded, which is slightly lossy. Only one video track and one audio track are kept; extra audio tracks and subtitles are left out.
• A width or height that is an odd number of pixels is trimmed by one pixel, because video encoders need even sizes.
• HDR video (for example from a recent iPhone) is converted to normal SDR colors, and 10-bit video becomes 8-bit, so it plays everywhere.
• Audio with more than two channels (5.1 surround) is mixed down to stereo.
• Files up to 150 MB are accepted. Long or very high-resolution videos can take several minutes, and a conversion that runs past about 4 minutes is stopped with a message.
