VOB is the DVD Video Object format that sits in the VIDEO_TS folder on a disc, and it carries MPEG-2 video with AC-3 or PCM audio. Converting your AVI to VOB gives you a file that fits a DVD authoring project or plays on a standalone DVD player. EchoWave does it in your browser, free and with no signup. If you just want to watch the clip on a phone or computer, AVI to MP4 is the easier route.

What changes from AVI 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 AVI.
  • 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

AVI to VOB questions

Why convert AVI to VOB?
VOB is the video format used on DVDs, so people convert AVI to VOB to author a disc, to feed a DVD menu program, or to match a DVD player that does not read AVI. If you only need to watch the clip on a computer or phone, convert AVI to MP4 instead.
What plays a VOB file?
DVD players read VOB natively, and on a computer VLC opens it without any extra setup. Many default phone and browser players do not handle VOB, so if you want broad playback rather than a disc, MP4 is the more compatible choice.
Does converting AVI to VOB lose quality?
VOB uses MPEG-2 video, so your AVI is re-encoded to the DVD standard and the result can only be as good as the source, never sharper. MPEG-2 is an older codec built for discs, so for modern, high-efficiency playback a format like MP4 keeps more quality at a smaller size.
Is the AVI to VOB converter free?
Yes. EchoWave converts AVI to VOB with no signup, no account to create, no trial, and no watermark. Upload your AVI, convert it, and download the VOB from your browser.
How do I convert AVI to VOB?
Upload your AVI, choose VOB as the output format, and start the conversion. When it finishes, download the VOB, or open the clip in the editor first to trim it or add captions.
Can I burn the VOB straight to a DVD?
A VOB is the right kind of file for a disc, but burning still needs DVD authoring software to build the VIDEO_TS structure and any menus. The converter gives you the VOB; a tool like DVD Flick or your burning app assembles and writes the disc.
Does the AVI to VOB converter work on Mac and Windows?
Yes. The converter runs in any browser, so you can convert AVI to VOB on macOS, Windows, Chromebook, and Linux. There is nothing to install and no account to create.
Can I convert a large AVI from a camcorder?
Yes. There are no file-count limits on these pages, and large AVI files are supported. A long camcorder recording simply takes a little longer to upload and convert before the VOB is ready.
