Frequently asked questions
What is a VOB file?
VOB (Video Object) files are what a DVD stores its movie in, inside the VIDEO_TS folder. They hold MPEG-2 video, usually Dolby Digital (AC-3) audio, and the DVD menus and subtitles. Many computers and phones will not play them, and they are large, so converting to H.264 MP4 usually makes the video several times smaller.
Can it convert a commercial DVD?
No. Commercial DVDs are encrypted with copy protection, and this tool cannot remove it. It converts VOB files from unprotected discs, such as DVDs you burned yourself, camcorder and DVD-recorder discs, and files you have already legitimately decrypted. If a VOB cannot be read, the disc is most likely protected.
My DVD has several VOB files — how do I convert the whole movie?
A DVD splits the movie into files of about 1 GB, named like VTS_01_1.VOB, VTS_01_2.VOB and so on. VTS_01_0.VOB is only the menu. Join the numbered parts first (on Windows: copy /b VTS_01_1.VOB+VTS_01_2.VOB+VTS_01_3.VOB movie.vob), then convert the joined file. A browser can handle roughly 1–2 GB of output, so for a full-length movie, trimming it or running the generated ffmpeg command on your own computer works better.
What happens to DVD subtitles, menus and extra audio tracks?
Menus are not part of the converted video. If the disc has several audio tracks (for example different languages), you can pick which one goes into the MP4. DVD subtitles are stored as pictures rather than text, so they cannot be converted to MP4 subtitles.
Why is the audio kept as surround sound?
DVD audio is often 5.1 surround. The tool keeps it as 5.1 AAC at 384 kbps so you do not lose it. If you only listen on stereo speakers or headphones, set Channels to Stereo for a smaller file.
Is my video uploaded anywhere?
No. The conversion runs entirely in your browser using ffmpeg compiled to WebAssembly. Your video never leaves your device. Only the converter engine itself (about 32 MB) is downloaded, once, and cached by your browser.
What is Fast remux and when should I use it?
A VOB file is just a container. If the video inside is H.264 (or another format MP4 supports) and the audio is AAC, MP3 or AC-3, those streams can be moved into an MP4 container as they are. That takes seconds and loses no quality at all. The tool checks your file and picks this automatically when it is possible.
What do CRF and bitrate mean?
CRF (constant quality) lets the encoder spend as many bits as each scene needs: lower numbers mean better quality and bigger files, around 18 looks near-lossless, 23 is the default and 28 is noticeably smaller. A target bitrate instead aims for a fixed number of kilobits per second, which gives a predictable file size but variable quality.
Why is re-encoding slow, and is there a size limit?
Re-encoding runs on a single CPU thread inside the browser (H.264 only), so it is usually near real-time speed or slower for HD. The finished MP4 also has to fit in browser memory, which in practice limits output to roughly 1 to 2 GB. For a long movie, use Fast remux, trim it, or copy the generated command and run it with ffmpeg on your own computer.
What happens to subtitles?
MP4 supports text subtitles only. SRT, ASS/SSA and WebVTT tracks are converted to the MP4 text format, and you can also save a track as a separate .srt file. Picture-based subtitles from Blu-ray or DVD (PGS, VobSub) cannot be converted.
