VOB to MTS Converter

How to Convert VOB to MTS Online

1. Upload Your VOB File: Drag and drop or click "+ Add Files" to select one or more VOB files from your DVD rip (typically named VTS_01_1.VOB, VTS_01_2.VOB, etc.). Batch upload is supported, so you can convert every chapter file from a VIDEO_TS folder in one pass.
2. Pick Quality Preset and Codec: Default Quality Preset is Very High (Recommended). Drop to High or Medium to roughly halve the file size, or step up to Highest for archival masters. The Video Codec defaults to H.264 (the AVCHD standard) — keep it for camcorder and Blu-ray player compatibility. AAC handles audio by default; switch to AC-3 if your target player expects Dolby Digital like the original DVD.
3. Resize and Trim (Optional): Use Video resolution to keep original, scale by Resolution Percentage, pick a Preset Resolution (480p, 576p, 720p, 1080p, 1080i for native AVCHD), or set custom Width x Height. Use Trim with a Time Range to extract a single chapter or skip the DVD menu intro. Target a Specific file size or set a Constant/Variable Bitrate if your camera or player has a bitrate cap.
4. Convert and Download: Click Convert. Files process server-side and download directly to your browser — no sign-up, no watermark, no installs.

Why Convert VOB to MTS?

VOB (Video Object) is the legacy MPEG program stream container DVDs use, carrying MPEG-2 video, AC-3/PCM audio, subpictures, and navigation data, with each segment hard-capped at 1 GiB for FAT32 compatibility. MTS is the file extension AVCHD camcorders write — an MPEG-2 transport stream wrapping H.264/MPEG-4 AVC video and Dolby AC-3 or linear PCM audio, jointly developed by Sony and Panasonic in 2006 for HD consumer recording. Converting from VOB to MTS re-encodes MPEG-2 into H.264 so the output drops to roughly half the size at comparable visual quality and slots straight into AVCHD workflows.

• Get DVD footage into a camcorder timeline — Sony Vegas, Pixela ImageMixer, and the AVCHD project structures used by Handycam and Panasonic Lumix camcorders expect MTS/M2TS clips. MTS lets you drop digitized DVD chapters next to native AVCHD clips without re-wrapping again.
• Burn HD discs from old DVDs — AVCHD discs play in most Blu-ray players from a standard DVD-R, but only if the video is H.264 in a transport stream. MTS is the source format; VOB isn't.
• Survive transport-stream playback — MTS's transport stream is packetized and resyncs from any point, so partial files, USB sticks pulled mid-write, and broadcast-style streaming all degrade gracefully. VOB's program stream is meant for sequential disc playback and tends to fail hard on incomplete reads.
• Cut file size roughly in half — H.264 (used by MTS) is two generations newer than MPEG-2 (used in VOB). A 4 GB DVD rip typically produces a 2-2.5 GB MTS at visually matched quality, freeing space on SD cards and external SSDs.
• Archive old camcorder DVDs — many 2005-2012 consumer DVD camcorders (Sony DCR-DVD, Panasonic VDR) wrote to mini-DVDs as VOB. Converting to MTS gets the footage off the optical media before the disc itself rots.
• Edit in software that hates VOB — Adobe Premiere, DaVinci Resolve, and FCP X all import MTS/M2TS reliably, while VOB often imports without audio or with broken durations because of its DVD-specific stream structure.

Frequently Asked Questions

Why does my MTS look softer than the original VOB?

DVD VOB is standard definition (720x480 NTSC or 720x576 PAL) — it doesn't contain HD information to begin with. Converting to MTS doesn't add detail; it just changes the wrapper and re-encodes with H.264. If the output looks softer, that's the H.264 encoder smoothing low-detail MPEG-2 macroblocks. Try the Highest Quality Preset or set a higher Constant Bitrate, and keep the resolution at original 720x480 / 720x576 rather than upscaling.

Should I pick H.264, H.265, or MPEG-2 for the MTS output?

H.264 is the right answer for almost every MTS use case — it's literally the AVCHD spec's required codec, so any AVCHD camcorder, Blu-ray player, or Sony/Panasonic editor will accept it. H.265 (HEVC) is smaller at the same quality but is not part of AVCHD and many camcorder editors reject it. MPEG-2 in an MTS wrapper exists for broadcast and ATSC over-the-air streams, but consumer devices expecting "MTS files" expect H.264.

What's the difference between MTS and M2TS?

MTS and M2TS are the same MPEG-2 transport stream payload. MTS is the extension AVCHD camcorders write to SDHC cards; M2TS is the extension Blu-ray discs (and most computers, after import) use. Many editors rename .MTS to .m2ts on ingest. Functionally identical files. If you specifically need .m2ts for Blu-ray authoring, use our VOB to M2TS converter instead.

Will my VOB chapters merge into one MTS, or stay split?

Each VOB file you upload converts to a separate MTS by default. DVDs split a single movie across several 1 GiB VOBs (VTS_01_1.VOB, VTS_01_2.VOB, ...), so the result is a set of MTS chapters. If you want a single continuous file, concatenate the VOBs into one input before uploading, or use a downstream join tool — MTS's transport stream is designed for clean concatenation.

Does the audio survive the conversion?

Yes. AC-3 (Dolby Digital) tracks from DVD pass cleanly into MTS since AVCHD supports AC-3 natively. PCM and MPEG-1 Audio Layer II tracks are transcoded to AAC or AC-3. Multi-channel 5.1 mixes are preserved when present; default output is stereo if the source is stereo. Subtitle subpictures from VOB are NOT carried over — MTS doesn't support DVD-style bitmap subtitles, so burn them in beforehand or extract them as a separate SRT.

Why is the converted file still large even at "Low" preset?

Two reasons: HD resolution targets and bitrate floors. If you've selected an HD Preset Resolution (720p+) the encoder has more pixels to spend bits on than the original SD VOB needed. Drop the resolution back to Keep original (which preserves 720x480 or 720x576), or set a Specific file size target in the bitrate group — the encoder will then size to fit rather than to a quality target.

Can I trim out the DVD menu intro before converting?

Yes. Open Advanced Options, enable Trim, set the mode to Time Range, and enter a start time after the intro and an end time before the closing credits. The trimmed segment converts in a single pass — no separate cutting step. If you only need to clip the VOB before converting (no format change), use Trim VOB directly.

Is there a file size limit?

Per-file uploads are capped at our standard processing limit (check the upload panel for the current value). Note that DVDs split content across multiple 1 GiB VOBs by design, so each VOB chapter usually fits comfortably. If you have a single oversized VOB, consider compressing first with Compress VOB or trim to the segment you actually need.

What's the reverse direction — MTS to VOB for DVD burning?

If you have AVCHD camcorder footage and want to author a playable DVD-Video disc, use our MTS to VOB converter. DVD-Video requires MPEG-2 video and the disc's specific VTS structure, so direct MTS playback in standard DVD players generally isn't supported without that conversion.
