Free online OGV to M2V converter

DVD authoring tools, broadcast workflows, and older MPEG-2 editing systems may require an M2V elementary video stream instead of an OGV file. Converting removes OGV's container and audio track while re-encoding its video as MPEG-2.

What the OGV format is

OGV is an Ogg container commonly used for video encoded with Theora and audio encoded with Vorbis or Opus. It appears in open-source software, web archives, educational recordings, and projects created with tools such as FFmpeg, VLC, Kdenlive, and older screen-recording applications.

An OGV file can contain video, audio, subtitles, and metadata. The .ogv extension usually identifies the video-oriented Ogg variant, but the exact codecs still depend on how the file was created.

What the M2V format is

M2V is an MPEG-2 video-only elementary stream. It contains compressed video frames but no audio, container-level chapters, or normal multimedia metadata. DVD authoring applications and some legacy broadcast or editing systems accept M2V alongside a separate audio stream.

MPEG-2 offers broad compatibility with DVD-related tools and older hardware. It is less efficient than newer codecs, so an M2V file normally requires more storage than an equivalent H.264 or H.265 video at similar visual quality.

How to convert OGV to M2V

Using FFmpeg

FFmpeg is the most controllable desktop method. Run this command in the directory containing the source file:

ffmpeg -i input.ogv -map 0:v:0 -c:v mpeg2video -pix_fmt yuv420p -b:v 6000k -f mpeg2video output.m2v

-map 0:v:0 selects the first video stream and prevents audio from being copied. -c:v mpeg2video performs the required MPEG-2 video re-encoding, -pix_fmt yuv420p improves compatibility, and -b:v 6000k sets the target video bitrate. Replace the filenames and adjust the bitrate for the intended device or authoring specification.

For quality-based encoding instead of a fixed bitrate, use a lower constant-quality value for higher quality and larger output:

ffmpeg -i input.ogv -map 0:v:0 -c:v mpeg2video -pix_fmt yuv420p -q:v 2 -f mpeg2video output.m2v

For a DVD-specific result, use the resolution, frame rate, aspect ratio, bitrate, and interlacing requirements of the authoring application. A typical PAL example is:

ffmpeg -i input.ogv -map 0:v:0 -vf scale=720:576 -r 25 -c:v mpeg2video -pix_fmt yuv420p -b:v 6000k -f mpeg2video output.m2v

Do not apply DVD dimensions or frame rates automatically to material intended for another MPEG-2 workflow; changing them can distort motion or alter the display shape.

Using the built-in online converter

You can convert the file for free on the 101convert.com website without installing software. Select the OGV file, choose M2V as the output format, start the conversion, and download the resulting video stream. Check the output specification first if the file must meet a DVD or broadcast profile.

Quality, compatibility, and limitations

The conversion is lossy because Theora video is decoded and then compressed again as MPEG-2. A higher bitrate can reduce additional MPEG-2 artifacts, but it cannot restore detail already lost in the OGV source.

M2V contains no audio. If the source has sound, retain the original audio or export it separately and give both streams to the authoring application. If a single file with audio is required, an MPEG program stream such as .mpg is more appropriate than M2V.

FFmpeg may preserve the source frame rate and dimensions unless options change them. Confirm the result with ffprobe output.m2v; elementary streams have limited metadata, so some players may show incomplete duration or seek information even when the video is valid.
