OGV to MPEG-2 Converter

OGV to MPEG-2 Converter

OGV is the Ogg video container, normally carrying Theora video with Vorbis audio — an open, royalty-free format from the Xiph.Org Foundation. MPEG-2 (ISO/IEC 13818, ITU-T H.262) is the older DVD-and-broadcast codec, saved as .mpg, .mpeg, or .m2v. This conversion transcodes an open web/desktop file into the format DVD authoring tools and legacy hardware expect. Because both codecs are dated, it is worth knowing exactly when MPEG-2 is the right target — and when it is not.

How to Convert OGV to MPEG-2

1. Upload Your OGV File: Drag and drop your .ogv file onto the page, or click "Add Files" to browse. You can queue several files and convert them with the same settings.
2. Pick a Quality Preset: Open Advanced Options and choose a Quality Preset (the default is "Very High (Recommended)"), or switch to Constant Bitrate or Specific file size if you are authoring a DVD that must fit a disc.
3. Set Resolution (Optional): Keep the original frame size or choose a Preset Resolution. DVD-standard MPEG-2 is 720×480 (NTSC) or 720×576 (PAL); use the Trim controls if you only need a clip.
4. Convert and Download: Click Convert and download your .mpg file. No sign-up, no watermark.

Frequently Asked Questions

Should I really convert OGV to MPEG-2, or to MP4 instead?

For general playback on phones, browsers, and TVs, convert to MP4 (H.264) instead — it is far smaller than MPEG-2 at the same quality and plays almost everywhere. See OGV to MP4. Choose MPEG-2 only when a specific tool requires it: DVD authoring software, an older non-linear editor, or capture/broadcast hardware that ingests MPEG-2.

Will converting OGV to MPEG-2 improve the video quality?

No. Re-encoding cannot add detail that was not already in the Theora source — it can only preserve or lose it. MPEG-2 is also less efficient than Theora, so to avoid visible quality loss the MPEG-2 file usually has to be substantially larger. Keep the Quality Preset high if you want the output to look like the original.

Why is OGV hard to play now, but DVDs still use MPEG-2?

Browsers moved on from Theora: Chrome disabled it in version 120 (December 2023) and Chromium removed it in version 123 (March 2024), Firefox disabled it by default in 126, and Safari never supported it. MPEG-2 survives because it is baked into the DVD-Video and digital-broadcast standards, so DVD players and broadcast gear still decode it natively even though newer codecs are more efficient.

What resolution and frame size should MPEG-2 output use for a DVD?

DVD-Video MPEG-2 is 720×480 at 29.97 fps for NTSC, or 720×576 at 25 fps for PAL. In our testing, leaving the resolution on "Keep original" works for general playback, but if the file is destined for DVD authoring you should pick the matching Preset Resolution so your authoring software does not re-scale it a second time.

Is MPEG-2 still patent-encumbered or free to use?

The MPEG-2 patent pool expired worldwide on January 3, 2024 (the last US patent lapsed in February 2018), with a single remaining patent in Malaysia. In practice MPEG-2 encoding and decoding are now effectively royalty-free, which is one reason it is still convenient for archival DVD work.

What happens to the audio when I convert from OGV?

The Vorbis audio inside your OGV file is re-encoded to an MPEG-2-compatible audio stream (such as MP2 or AC-3) so the resulting .mpg plays in DVD and broadcast workflows. The conversion keeps your audio in sync with the video automatically.

Is it safe to upload my OGV file here?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public. If you would rather stay on an open, royalty-free format, OGV to WebM is a smaller, modern alternative to MPEG-2.

How do I make the MPEG-2 fit on a DVD?

A single-layer DVD-5 holds about 4.7 GB and a dual-layer DVD-9 about 8.5 GB, and that budget covers both video and audio. To hit a target, open Advanced Options and switch from the Quality Preset to "Specific file size" (or set a Constant Bitrate) so the MPEG-2 stream is sized to your disc — leaving headroom for the audio track and any menu your authoring tool adds. As a rough guide, DVD-Video video bitrate peaks near 9.8 Mbit/s, so a roughly hour-long program fits a DVD-5 comfortably at good quality; longer runtimes need a lower bitrate or a dual-layer disc.

What is the difference between .mpg, .mpeg, and .m2v?

.mpg and .mpeg are the same thing — an MPEG program stream that multiplexes video and audio together into one playable file, which is what this converter outputs. .m2v is different: it is an MPEG-2 elementary stream containing video only, with no audio, used mainly as an intermediate that DVD-authoring software muxes with a separate audio file. For general playback you want the .mpg/.mpeg program stream you get here; reach for .m2v only when an authoring workflow specifically asks for a video-only elementary stream.
