How to Convert OGV to MP4

OGV is the Ogg container holding Theora video — an open-source video codec that was Firefox's preferred web video format before H.264 became universally licensed. OGV files don't play on iOS, Safari, or many devices without VLC. Converting to MP4 H.264 provides universal playback across all modern platforms.

Convert OGV to MP4 with free tools

  1. 1

    FFmpeg (command line)

    Basic conversion: `ffmpeg -i input.ogv -c:v libx264 -crf 23 -c:a aac -b:a 128k output.mp4`. FFmpeg decodes Theora video and Vorbis audio. CRF 23 gives good quality at a reasonable size. For web streaming, add `-movflags +faststart`.

  2. 2

    VLC (GUI, all platforms)

    VLC reads OGV on every platform. Open VLC → Media → Convert/Save (on a Mac: File → Convert / Stream) → add the OGV → Profile: Video - H.264 + MP3 (MP4) → name the output .mp4 → Start. VLC handles both the Theora video and the Vorbis audio.

  3. 3

    HandBrake

    HandBrake opens OGV files: select the OGV source → H.264 or H.265 video → RF 22–23 → MP4 format → Start Encode. The preview shows a few seconds so you can check quality before converting.

Why convert OGV to MP4?

OGV was the open web's answer to H.264 in an earlier era. H.264 won — converting to MP4 brings OGV content into the universal playback ecosystem.

Frequently asked questions

What is OGV used for?
OGV was the open-source alternative to H.264 for web video, promoted by Mozilla from about 2009 to 2013. Websites needing Firefox support without a plugin served OGV alongside MP4. Today WebM (VP9/AV1) has replaced OGV, and OGV files are primarily legacy content from the 2009–2015 era.
Is Theora quality as good as H.264?
No — Theora is significantly less efficient than H.264. At equivalent bitrates, H.264 produces noticeably better quality. Theora is roughly comparable to MPEG-4 Part 2 (DivX/Xvid). Converting from Theora OGV to H.264 at the same visual quality often produces a smaller file, though a fixed-quality setting such as CRF 23 can come out larger than a low-bitrate Theora source.
Can browsers still play OGV files?
Not reliably any more. Chrome turned Theora off in version 120 and removed it in version 123 (2024), so Edge and other Chromium browsers lost it too. Firefox turned Theora off by default in version 126. Safari never played it. For web use, convert to MP4 (H.264) or WebM.
