VOB to TS Converter

How to Convert VOB to TS Online

1. Upload Your VOB File: Drag and drop or click "+ Add Files" to select one or more .vob files from your computer. Batch is supported, and you can queue the sequential VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB chapters from a DVD's VIDEO_TS folder in order.
2. Pick a Video Codec: Default is H.264 (broadest player support). Choose H.265 (HEVC) for ~50% smaller files at the same visual quality, MPEG-2 if you want to keep the DVD's native codec (re-encoded at a visually-lossless preset), or MPEG-4/XVID/DivX for legacy set-top boxes. Audio Codec defaults to AAC; switch to AC-3 to keep the DVD's original Dolby Digital surround channels.
3. Set Quality, Resolution, and Trim (Optional): Use the Preset dropdown (Lowest / Low / Medium / High / Very High (Recommended) / Highest) for one-click CRF tuning, or switch to Constant Bitrate / Variable Bitrate / Specific file size to hit a target megabyte count. Use the Video resolution group to keep original, pick a Preset Resolution (480p, 720p, 1080p, 1440p, 4K), scale by Resolution Percentage, or set custom Width x Height. Use Trim to set a Time Range (HH:MM:SS) — useful for skipping the DVD's intro warning screens.
4. Convert and Download: Click "Convert". Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert VOB to TS?

VOB is the MPEG program stream container that DVD-Video discs use inside the VIDEO_TS folder. It carries MPEG-2 video plus AC-3, DTS, MPEG-1 Layer II, or LPCM audio along with subtitles and menu navigation, but it's locked to a 1 GiB per-file ceiling and to a packet structure built for the relatively error-free read path of an optical disc. MPEG-2 Transport Stream (TS / .ts), standardised in 1995 as ISO/IEC 13818-1, wraps the same video and audio essence into 188-byte fixed-length packets stamped with the 0x47 sync byte and program clock references at least every 100 ms — a layout designed for terrestrial broadcast, satellite, IPTV, and HLS where packets routinely arrive late or get lost.

• Stream legacy DVD content over HLS or DVB — TS is the segment format inside HTTP Live Streaming, ATSC, DVB-T/S, and ISDB-T. Convert a VOB chapter to TS and a Wowza, nginx-rtmp, or FFmpeg encoder can serve it to web players or set-top boxes without further muxing.
• Recover from packet loss on flaky links — the constant 188-byte packetisation and continuity-counter fields let a decoder re-sync after a dropped chunk. A scratched DVD ripped straight to VOB will halt at the bad sector; the TS re-encode can be set to skip the damaged GOPs.
• Append several DVD chapters into one file — DVD authoring splits a title across VTS_01_1.VOB, VTS_01_2.VOB, etc. at the 1 GiB boundary. Converting each to TS produces a self-synchronising stream you can concatenate with a simple cat (binary append) because every TS packet is independently decodable.
• Feed hardware that prefers .ts — Panasonic, JVC, and Sony AVCHD/AVCCAM camcorders record to MTS/M2TS (TS variants), and many Smart TVs and PVRs index .ts faster than .vob because the sync byte makes seek scanning O(n) trivial.
• Drop the DVD navigation overhead — .vob files lean on companion .ifo and .bup files for chapter and angle metadata. Once converted to TS the playback is self-contained, so you can store, email, or upload a single file instead of a folder.
• Re-encode to modern codecs in one pass — instead of keeping MPEG-2, switch the Video Codec to H.264 or H.265 to shrink a 4.7 GB DVD rip to ~700 MB without obvious quality loss, then keep the TS container for streaming.

Frequently Asked Questions

What's the difference between a TS file and an M2TS file?

Both are MPEG-2 Transport Streams using 188-byte packets and the 0x47 sync byte. .m2ts (BDAV MPEG-2 Transport Stream) is the variant Blu-ray and AVCHD camcorders use; it prepends an extra 4-byte timecode header to each packet (192 bytes total) so the disc player can do frame-accurate seeking. Plain .ts is the broadcast / IPTV variant with no timecode prefix. If you need Blu-ray or AVCHD authoring output, use VOB to M2TS instead.

Will the DVD subtitles and menus survive the conversion?

No. DVD subtitles live in the .vob as VobSub bitmap streams indexed by the .ifo file, and the menus are MPEG-2 still images with button overlays defined in the IFO. Converting just the VOB drops both. If you need the captions, demux them separately with a tool like vobsub2srt and re-mux the resulting .srt into the TS output. The DVD-style menu screens can't be reproduced in a flat TS file.

Can I keep the original AC-3 5.1 surround track?

Yes — set Audio Codec to AC-3 in Advanced Options. The output keeps all six channels of the Dolby Digital mix at a matching bitrate (typically 384 or 448 kbps for 5.1). The audio is re-encoded to AC-3 rather than stream-copied, but staying on AC-3 avoids the downmix and heavier quality hit that switching to AAC would introduce.

Why is my VOB split into VTS_01_1.VOB, VTS_01_2.VOB, etc.? Do I convert them separately or together?

DVD-Video specifies a 1 GiB maximum per VOB, so a 4 GB film is split into roughly four numbered chunks that play seamlessly in order. Upload all the chunks for a single title (same VTS_01_* prefix) in order — the queue will encode each to TS, and because every TS packet is independently decodable you can join the outputs with cat VTS_01_1.ts VTS_01_2.ts... > full.ts (or in Windows copy /b file1.ts + file2.ts full.ts). The result plays as one continuous stream.

Should I pick MPEG-2 or H.264?

Pick MPEG-2 if you want to stay closest to the DVD's original picture — it re-encodes to the same codec at a high-quality preset, so the result is visually indistinguishable from the source and processes quickly. Pick H.264 or H.265 if you want a smaller file: a typical 4.3 GB DVD rip drops to roughly 700-900 MB at H.264 Very High preset with no visible quality loss on a phone or laptop. For broadcast or live-streaming workflows, H.264 in TS is the de facto standard (DVB-T2, ATSC 3.0, HLS).

Does TS support 4K or HDR?

The container does — .ts is what ATSC 3.0 uses to deliver 4K HDR over-the-air broadcast — but the source matters. DVDs are 720x480 (NTSC) or 720x576 (PAL) at SDR, so upscaling a VOB to 4K won't add real detail. Use Resolution Preset → 4K only if you need a specific output frame size for a downstream pipeline; otherwise keep the original resolution or upscale only to 720p / 1080p.

Will my browser play the TS file directly?

Chrome, Edge, and Firefox don't have native HTML5 support for raw .ts files the way they do for .mp4. They can play TS segments served as part of an HLS playlist (m3u8), but a standalone .ts typically prompts a download. For local playback, use VLC, mpv, MPC-HC, or PotPlayer — all handle TS natively. If you want a single browser-playable file, convert to MP4 instead: see VOB to MP4.

Is there a file-size limit for uploads?

Free conversions on xconvert run up to 1 GB per file, processed on our servers. That covers a single DVD VOB chunk (the DVD spec caps each chunk at 1 GiB anyway). For larger archival rips or whole-title concatenations, register for a free account to raise the cap, or split the source first with Trim VOB and convert the chapters individually.

How is this different from converting VOB to MP4 or MKV?

MP4 is the right choice when you want the broadest player support (browsers, phones, smart TVs all play H.264 in MP4 natively) — use VOB to MP4. MKV is the right choice when you want to keep multiple subtitle and audio tracks in one file for media-server playback — use VOB to MKV. TS is the right choice when the output feeds a broadcast encoder, HLS packager, AVCHD/M2TS authoring tool, or a player that scans for the 0x47 sync byte (most PVRs, IPTV STBs).
