Convert your MP4 to VOB, the DVD video object format that disc authoring tools and standalone DVD players expect. A VOB carries MPEG-2 video with AC-3 or PCM audio, so the modern H.264 inside your MP4 is re-encoded to the DVD standard during conversion. EchoWave runs free in your browser, with no signup and no watermark.

Estimate your VOB

A video's size is its bitrate times its length. Pick a bitrate and a length for a rough guide.

What changes from MP4 to VOB

  • The video is re-encoded to MPEG-2 and the sound to AC-3, the standard pair for VOB. A re-encode compresses the picture again, so the result is at best as sharp as the MP4.
  • Only the main video and one audio track are kept. Extra audio languages, subtitle tracks, and chapters are not copied, so keep the original if you need them.
  • VOB only accepts its own codecs, so this conversion always re-encodes, even if you choose Copy source stream.

Troubleshooting

If something looks off

The VOB will not play
Some players only handle a few codecs. Try VLC, which opens almost anything, or check that your app supports MPEG-2 video.
The file got bigger
A re-encode can change the size either way. VOB uses older compression than H.264, so a bigger file is normal.
My subtitles or second language are missing
Only the main video and one audio track are converted. Keep the original for its extra tracks, or burn subtitles into the picture in the editor.

FAQ

MP4 to VOB questions

Is the MP4 to VOB converter free?
Yes. EchoWave converts MP4 to VOB with no signup, no file-count limit, no trial, and no watermark. Upload your video, convert it, and download the VOB from your browser.
How do I convert MP4 to VOB?
Upload your MP4, choose VOB as the output format, and start. When it finishes, download the VOB file or open it in the editor to trim it before you author a disc.
Why convert MP4 to VOB?
VOB is the format used inside DVD-Video discs, so a DVD authoring tool or an older standalone player will often expect it. Converting an MP4 to VOB gives those tools the MPEG-2 video and DVD-style audio they were built to handle.
Does a VOB file play a DVD straight away?
Not on its own. A finished DVD also needs the surrounding folder structure and IFO and BUP files that a disc authoring program creates. The VOB holds the video and audio, and your DVD software wraps it into a playable disc.
Will converting MP4 to VOB reduce quality?
An MP4 usually stores efficient H.264 video, while VOB uses the older MPEG-2 codec, so the video is re-encoded to meet the DVD standard. A high bitrate keeps the picture as close as DVD allows, but converting cannot add detail the MP4 never had.
Should I pick NTSC or PAL?
It depends on where the disc will play. NTSC is standard in North America and Japan, while PAL is used across much of Europe, Africa, and Asia. Choose the one your target DVD player and TV expect so the video runs at the right frame rate.
Why is the VOB larger than my MP4?
MPEG-2, the codec inside a VOB, compresses less efficiently than the H.264 video in a typical MP4, so it needs a higher bitrate for the same quality. A bigger file is normal for DVD-style video.
Can I convert MP4 to VOB on Mac, Windows, iPhone, and Android?
Yes, the MP4 to VOB step is done in the browser, so it runs the same on macOS, Windows, a Chromebook, Linux, an iPhone, an iPad, or an Android device with nothing to download and no account needed. Keep in mind that the DVD authoring program you feed the VOB into afterwards is usually a desktop tool, so most people convert on a Mac or Windows machine where their disc software already lives.
What plays a VOB file on a computer?
VLC opens VOB files directly on Windows, macOS, and Linux, and most DVD playback software handles them too. For sharing or uploading the video, MP4 stays the easier format.
