Free online VOB to TS converter

Source format: VOB

VOB (Video Object) is the container format used on DVD-Video discs. It typically stores MPEG-2 video, AC-3 or DTS audio, subtitles, and navigation data. VOB files are commonly found in the VIDEO_TS folder of a DVD and are used by DVD authoring systems, disc rippers, and media players that support DVD playback.

VOB is useful for disc-based distribution, but it is less convenient for modern playback and editing because it is tied to DVD structure and may be split into multiple files.

Target format: TS

TS usually means MPEG transport stream (.ts). It is a robust container designed for streaming and broadcast delivery. TS is widely used for digital television, IPTV, recording devices, and streaming workflows because it can handle packet loss better than many file-based containers and can carry multiple audio, video, and subtitle streams.

Compared with VOB, TS is often easier to use in broadcast and streaming environments, and it is commonly accepted by media servers, set-top boxes, and editing tools that work with transport streams.

How to perform the conversion

The most reliable way to convert VOB to TS is with FFmpeg. In many cases, you can remux the streams without re-encoding, which preserves quality and is much faster than full conversion.

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt in the folder containing the VOB file.
3. Run a remux command such as ffmpeg -i input.vob -c copy output.ts.
4. If the VOB is part of a DVD set, make sure you choose the correct main title or combine the relevant VOB segments first.
5. Play the resulting output.ts in a media player to confirm that audio and video are intact.

If the VOB file has compatibility issues, you can re-encode instead of copying streams, for example by specifying a video codec and audio codec in FFmpeg. However, re-encoding is usually unnecessary unless the target device requires a specific format.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality, compatibility, and limitations

Remuxing from VOB to TS does not change the underlying audio or video quality, because the streams are copied as-is. This is the preferred method when the codecs inside the VOB are already compatible with TS.

Keep in mind that VOB files from DVDs may contain DVD navigation data, multiple audio tracks, or subtitles. Not every player or converter preserves all of these elements in the same way. Also, some VOB files are split into 1 GB segments, so converting only one segment may produce an incomplete result if the full title spans several files.

If the source VOB uses unusual DVD features or damaged sectors, the conversion may fail or produce glitches. In such cases, a re-encode or a DVD ripper that can handle disc structure may be needed.
