VIDEO_TS). Batch upload is supported, and the converter preserves the order of files you queue..mts AVCHD stream downloads immediately — no sign-up, no watermark, no email required.VOB (Video Object) is the MPEG-2 container that ships on every consumer DVD-Video disc, including DVDs burned by Sony, Panasonic, and Hitachi DVD camcorders from the early 2000s. AVCHD, jointly introduced by Sony and Panasonic in 2006, repackages H.264 video and Dolby AC-3 audio inside an MPEG transport stream with the .mts or .m2ts extension. Converting VOB to AVCHD is the standard path when you want DVD-era footage to play on Blu-ray hardware, sit alongside HD camcorder clips in an editing timeline, or live on an AVCHD-burned data disc instead of fragile 4.7 GB DVD-R.
.vob files generally is not, unless the disc is authored as DVD-Video.| Property | VOB | AVCHD |
|---|---|---|
| Container | MPEG-2 Program Stream | MPEG-2 Transport Stream |
| File extension | .vob |
.mts (camera) / .m2ts (imported) |
| Typical video codec | MPEG-2 Part 2 | H.264 / MPEG-4 AVC |
| Typical audio codec | AC-3, MPEG-1 Layer II, LPCM | Dolby AC-3, linear PCM |
| Max resolution | 720x480 (NTSC) / 720x576 (PAL) | 1920x1080 (also 1440x1080, 1280x720) |
| Typical bitrate | up to ~9.8 Mbit/s combined | up to 18 Mbit/s (DVD media) / 24 Mbit/s (BD/SD card) / 28 Mbit/s (AVCHD 2.0) |
| Native playback | DVD players, PCs with DVD software | Blu-ray players, PS3/PS4, AVCHD camcorders, modern TVs |
| Year introduced | 1996 (DVD-Video spec) | 2006 (Sony/Panasonic) |
| Best for | Standard-definition DVD authoring | HD camcorder archives, Blu-ray-compatible discs |
| Preset | Approx. video bitrate at 1080p | Best for |
|---|---|---|
| Highest | ~24 Mbit/s | Archival master, near-Blu-ray quality |
| Very High (default) | ~18 Mbit/s | Closest visual match to source VOB after upscaling |
| High | ~12 Mbit/s | Streaming-quality archive, smaller files |
| Medium | ~8 Mbit/s | Family-share copies, USB-stick libraries |
| Low / Lowest | ~4 Mbit/s or less | Phone preview / fitting longer content on SD card |
AVCHD's spec caps total bitrate at 18 Mbit/s when the stream is burned to a DVD-based AVCHD disc and 24 Mbit/s when authored to Blu-ray, an SD card, or AVCHD 2.0 (Progressive) targets, per the AVCHD specification published by Sony and Panasonic.
No — the conversion re-encodes the existing 720x480 (NTSC) or 720x576 (PAL) pixels into H.264, but it can't recover detail that was never recorded. If you pick a 1920x1080 preset the converter upscales (interpolates new pixels); the file is technically "HD" by resolution but visually no sharper than the source. Pick "Keep original" resolution unless you specifically need a 1080p frame for editing alongside HD clips.
Yes, DVD-Video chops anything over 1 GB into sequential VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.) so that older filesystem readers can handle them. Upload them in order; the encoder treats them as one logical stream and outputs a single AVCHD file. If you'd rather work with a clean MP4 master first, see VOB to MP4.
Usually, yes. AVCHD on a 4.7 GB DVD-R (often called an "AVCHD disc") is recognised by most Sony, Panasonic, LG, and Samsung Blu-ray players, the PS3, and the PS4. The Wikipedia AVCHD entry notes that "not all Blu-ray players support AVCHD video authored on DVD media," so verify your model's manual — older Pioneer and some Oppo decks are picky. For maximum compatibility, burn to BD-R.
AVCHD supports Dolby AC-3 (the original DVD audio codec) and linear PCM in pro mode. Because VOB usually ships AC-3 already, the converter can pass the audio through with minimal generation loss. Switch the Audio Codec in Advanced Options if you specifically need PCM for editing.
This happens when you upscale resolution, pick a Highest preset, or change Constant Bitrate to a higher value than the source. A 9.8 Mbit/s VOB transcoded to 24 Mbit/s AVCHD at the same resolution gets bigger, not smaller. Drop to Very High or Medium, or use Constant Quality (CRF) around 20-23 for size-efficient encodes that still match the source visually.
AVCHD allows multiple audio tracks (up to seven 5.1 streams per the spec) and supports presentation-graphic subtitle streams, but most online converters only carry the first audio track and discard DVD subtitle streams (which are bitmap-based and embedded in the VOB). If you need every audio track preserved, transcode the audio separately and remux. The visible subtitle text is not converted.
Yes, if they're inside the same VOB. DVD menu segments often live in VTS_01_0.VOB (the menu set) while the main feature is in VTS_01_1.VOB onward — uploading only the title VOBs avoids the menus entirely. If you have a single concatenated dump, use the Trim option with a Time Range to skip the leader and trailer. See Trim VOB if you'd prefer to clip first and convert second.
.mts and .m2ts extensions?They're the same MPEG-2 Transport Stream container. Camcorders record to the SD card with the .mts extension; Sony's PlayMemories and most NLEs rename it to .m2ts on import to match the BDAV transport stream convention used inside Blu-ray. The bytes inside are identical, and players accept either. This converter outputs .mts by default.
Yes — both ingest AVCHD natively. iMovie expects to see the full AVCHD folder structure (BDMV/STREAM/00000.MTS) when importing from a camera, but it will also import a stand-alone .mts file by dragging it into the media browser. Final Cut Pro X imports .mts directly. If you need an MP4 instead, run AVCHD to MP4 after this conversion.
