VOB to WMV Converter

How to Convert VOB to WMV Online

1. Upload Your VOB File: Drag and drop or click "Add Files" to select VOB files from a ripped DVD's VIDEO_TS folder (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Batch is supported — drop in the whole VIDEO_TS folder and convert every chapter at once.
2. Pick a Video Codec and Quality: Default is WMV2 (Windows Media Video 9, the standard inside.wmv files since Windows XP / Vista). Choose WMV1 for older Windows Media Player builds, or stay on WMV2 for Windows 7-11 and Office embeds. Audio defaults to WMA v2 — switch to WMA v1, MP3, or AC-3 if you need to keep the original DVD Dolby Digital track. Pick a Quality Preset (Highest → Lowest), target a File Size Percentage with auto-scale, set an exact MB target, dial in a Constant or Variable Bitrate, or fine-tune CRF / qscale for the WMV encoder.
3. Resize or Trim (Optional): DVD source is 720×480 NTSC or 720×576 PAL — leave at Original to preserve native DVD resolution, pick a preset (1080p / 720p / 576p / 480p / 360p / 240p), enter custom width × height, or scale by percentage. Use Trim with start time + duration in HH:MM:SS.sss format to drop FBI warnings, studio logos, menu loops, or split a multi-episode disc into separate WMV files.
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 WMV?

VOB (Video Object) is the container DVD-Video discs have shipped in since 1996, holding MPEG-2 video, AC-3 / DTS / LPCM audio, and bitmap subtitles inside the VIDEO_TS folder. WMV (Windows Media Video) is Microsoft's container, native to every Windows install since Windows XP and the default output of Windows Movie Maker, Windows Media Encoder, and most legacy corporate authoring tools. Converting a DVD VOB to WMV is the right move when the destination is a Windows-only environment — old PowerPoint decks, legacy intranet portals, Windows Media Player libraries, or Camtasia 7-era training archives. For phones and Macs, convert to MP4 instead.

• Digitizing a DVD library into Windows Media Player — Family wedding, vacation, and graduation DVDs that are slowly degrading on the shelf (DVD-R dye-layer rot kicks in at 10-30 years) play natively in Windows Media Player as WMV with no extra codec packs. A 4.7 GB single-layer DVD typically lands at 1-1.5 GB WMV.
• Embedding DVD clips into PowerPoint or Word — Office 2007/2010/2013 embeds WMV cleanly via Insert → Video. VOB and MP4 either need a codec pack or trigger "media not available" on a different machine. WMV is the safe corporate format.
• Legacy intranet and SharePoint hosting — Windows Media Services and older SharePoint deployments stream WMV natively via mms:// and http:// progressive download. VOB cannot be served to a browser at all.
• Camtasia and Windows Movie Maker workflows — Camtasia 7-9 and Windows Movie Maker (Vista / 7 era) import WMV directly as a source clip; VOB requires a separate demux pass first.
• Archiving training and CCTV DVDs onto a Windows file server — Most pre-2018 enterprise CCTV DVRs export WMV by default. Converting DVD-based training archives to WMV keeps the whole library uniform on a Windows-Server / NAS share.
• Older Windows tablets and Surface RT-era devices — Devices that predate the Movies & TV app rely on Windows Media Player, which plays WMV natively but never shipped DVD VOB support.

Frequently Asked Questions

Will I lose quality converting VOB to WMV?

Not visibly at default settings. DVD VOB is already lossy at 4-8 Mbps MPEG-2, and WMV2 at "Highest" quality preset reproduces that source at roughly 1.5-2 Mbps with no perceptible loss on a normal display. Re-encoding from MPEG-2 to WMV is generationally clean since both are DCT-based codecs. For a tighter archive, drop to High or Medium and the file will land at 600-900 MB per hour of DVD material.

How do I convert all VOB files from a DVD's VIDEO_TS folder?

Open the VIDEO_TS folder on the ripped DVD, select all VTS_*.VOB files (VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB, etc.), and drop them into the upload area. Each file converts to its own WMV in parallel. To stitch them back into a single movie, run the conversion first then merge the resulting WMV files with our Merge Video tool.

Can I keep the DVD's Dolby Digital audio track?

The default audio codec for WMV output is WMA v2 (Windows Media Audio 9), which is what Windows Media Player expects. If you need the original DVD AC-3 (Dolby Digital) preserved, switch the audio codec to AC-3 — most modern Windows Media Player builds decode AC-3 inside a.wmv container, though some legacy players will only play WMA. For maximum corporate / Office compatibility, leave it on WMA v2.

What resolution should I use for DVD VOB sources?

Standard DVDs are 720×480 (NTSC, USA / Japan) or 720×576 (PAL, Europe / Australia). There's no benefit to upscaling beyond the source — keep "Original" or pick the 480p / 576p preset to match the source. Upscaling to 720p or 1080p only inflates the file size; the actual detail in the picture is bound by the DVD's SD source.

Why convert to WMV instead of MP4?

WMV is the right choice when the destination is Windows-only — older Windows Media Player libraries, embedded video in PowerPoint / Word, legacy SharePoint or intranet streaming, Camtasia 7-9 imports, or training archives that need to live on a Windows file server. For phones, Macs, smart TVs, social media, or modern web browsers, MP4 is the correct target — WMV has no native playback support outside of Windows.

How much smaller will the WMV be than the original VOB?

Typically 65-80% smaller. A 4.5 GB single-layer DVD VOB usually converts to 1-1.5 GB WMV at the "Highest" preset, 700-900 MB at Medium, or under 500 MB at Low. A dual-layer 8 GB DVD lands around 2-2.5 GB at high quality. Choose the WMV3 / VC-1 codec to push those numbers about 20% lower.

What about the DVD subtitles?

DVD subtitles are bitmap-based (VobSub) — they are images, not text, and WMV doesn't support bitmap subtitle tracks. Subtitles either get burnt into the picture during conversion or are dropped. If full subtitle preservation matters, convert to MKV with VOB to MKV — MKV supports both text and bitmap subtitle tracks natively.

Can I trim or split the VOB while converting?

Yes. The Trim option takes a start time and a duration in seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). Useful for dropping the FBI / studio warnings at the start of the disc, removing the menu intro loop, or splitting a multi-episode TV-show DVD into separate WMV files (run the conversion multiple times with different trim ranges).

What's the practical file size limit?

There is no fixed cap — conversion runs on our servers, so the limit is upload size and connection speed and the upload time. A full dual-layer DVD (8 GB) works on a desktop with 8 GB+ RAM. Multi-VOB DVD rips and full VIDEO_TS folder uploads work without the 1 GB free-tier cap that competitors like FreeConvert enforce, and there is no quantity cap on batch jobs.
