Need help?AV1 to VOB Converter
AV1 is the modern, royalty-free video codec from the Alliance for Open Media (released 2018), built for efficient HD and 4K streaming. VOB (Video Object) is the legacy container that DVD-Video discs use, carrying MPEG-2 video and Dolby Digital or MP2 audio. Converting AV1 to VOB is a downconvert: high-efficiency AV1 is re-encoded into the DVD-era MPEG-2 form that DVD authoring tools require, so this exists for one reason — burning footage to a standard DVD. A bare .vob is not a finished disc on its own; see the FAQ for what else a playable DVD needs.

How to Convert AV1 to VOB
- Upload Your AV1 File: Drag and drop or click "Add Files" to select one or more AV1 clips. Batch upload is supported, so you can queue several clips for one disc in a single pass.
- Pick a Quality Preset and DVD Audio: VOB is locked to MPEG-2 video by the DVD-Video spec, so that codec is the default. Audio defaults to MP2 (the universal DVD stereo track); AC3 (Dolby Digital) and DTS are also available under Audio Codec for surround. Choose a Quality Preset (the default is "Very High (Recommended)"), or open File Compression to set a Constant Bitrate in the DVD-friendly 4–9 Mbps range, a Variable Bitrate, or a Specific file size.
- Set Resolution or Trim (Optional): DVD is standard definition, so HD AV1 is downscaled. Under Video resolution, pick 720×480 for NTSC or 720×576 for PAL, or enter a custom Width × Height. Use Trim with a start time and duration to drop intros or split a long capture before authoring.
- Convert and Download: Click "Convert" and download your VOB file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Is a VOB file by itself a playable DVD?
No. A .vob holds the multiplexed MPEG-2 video and audio, but a DVD player also needs the navigation structure — the VIDEO_TS folder with its .IFO (information) and .BUP (backup) files — to find and play titles. This converter produces the VOB stream; to make a disc that plays in a set-top DVD player, load the VOB into DVD authoring software (such as DVDStyler, DVD Flick, or ImgBurn) to build the full VIDEO_TS structure, then burn it.
Will my AV1 file get larger when converted to VOB?
Usually yes, often by a wide margin. AV1 is roughly twice as efficient as the MPEG-2 codec DVDs require, so re-encoding the same footage to MPEG-2 at a watchable bitrate produces a much bigger file. DVD-Video also caps video at 9.8 Mbit/s, so even a high-bitrate source is held to that ceiling. The size jump is the price of DVD compatibility — there is no way to put native AV1 on a DVD-Video disc.
Why is the audio MP2 instead of AAC?
The DVD-Video spec does not allow AAC or Opus in a VOB. The legal options are MP2, AC-3 (Dolby Digital), DTS, and linear PCM. MP2 is the safe default for stereo playback on any DVD player; choose AC3 if you want Dolby Digital surround that matches what commercial discs ship with.
Do I lose quality going from HD AV1 to a DVD VOB?
Yes, and it is unavoidable. DVD-Video is standard definition only — 720×480 (NTSC) or 720×576 (PAL) — so a 1080p or 4K AV1 source is downscaled to fit. On top of that, MPEG-2 is far less efficient than AV1, so fine detail and smooth gradients soften compared with the original. Keep the bitrate generous (closer to the 9.8 Mbit/s ceiling) to minimize added compression artifacts.
Should I pick NTSC (480p) or PAL (576p)?
Match the region of the player you plan to use. NTSC (720×480) is standard in North America and Japan; PAL (720×576) is standard across most of Europe, Australia, and parts of Asia. Most modern players and ripping tools handle both, but a region-correct frame avoids vertical scaling and keeps motion smooth.
Is it worth converting AV1 to VOB at all, or should I keep AV1?
Only convert if you specifically need a physical DVD that plays in a set-top player. For everything else — phones, smart TVs, web, archiving — keep AV1 or use our AV1 to MP4 converter, which preserves HD resolution and far smaller files. If you already have DVD VOB files and want a portable copy, the VOB to MP4 converter re-encodes the DVD stream to H.264 MP4 for modern playback.
How large a file can I convert, and is it private?
The practical limit is upload size and time rather than your hardware, since processing happens on our servers. In our testing, a 60-second 1080p AV1 clip re-encoded to DVD-spec MPEG-2 VOB at a 6 Mbps constant bitrate produced a file around 45 MB. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — never shared or made public.
