Free online VOB to VCD converter

What the VOB format is

VOB, or Video Object, is a DVD-Video container created by DVD authoring software such as DVDStyler, Nero, and professional DVD production tools. DVD discs store movie content in files such as VTS_01_1.VOB, usually alongside additional numbered VOB files, IFO navigation files, and BUP backups.

A VOB can contain MPEG-2 video, one or more audio streams, subtitles, menus, and DVD navigation data. The same title is often split across several VOB files, with each file limited to approximately 1 GB. Commercial DVDs may also use encryption; ordinary conversion tools cannot legally or technically process encrypted content without appropriate access.

What the VCD format is

VCD is a CD-based video format that stores MPEG-1 video in a defined disc structure. Standard video uses 352×288 pixels at 25 fps for PAL or 352×240 pixels at 29.97 fps for NTSC, with approximately 1,150 kbps MPEG-1 video and 224 kbps MPEG-1 Layer II audio at 44.1 kHz.

A VCD is useful for older standalone CD/DVD players, hardware with VCD support, and archival or sharing workflows that specifically require the format. Its main practical advantages are low hardware requirements and broad compatibility with older players. A standard VCD holds about 74 or 80 minutes of video, but its low resolution and bitrate produce substantially lower quality than the original DVD.

How to convert VOB to VCD

Using 101convert.com

1. Open the VOB-to-VCD conversion page on 101convert.com; the service is free and does not require software installation.
2. Upload the relevant VOB file and choose VCD as the output format.
3. Select PAL or NTSC to match the source and the intended player, then start the conversion.
4. Download the resulting MPEG file. If you need a physical VCD, author the MPEG file into a VCD disc image and burn that image; copying the MPEG file directly to a data CD does not create a standards-compliant VCD.

Using FFmpeg and VCDImager

FFmpeg creates the VCD-compliant MPEG-1 program stream, while VCDImager creates the required disc image. Install both tools from their official desktop packages, then use the VOB containing the required title. If the title spans several VOB files, combine or extract the complete title first with DVD-aware software rather than converting only the first segment.

1. For a PAL source, run:

ffmpeg -i VTS_01_1.VOB -target pal-vcd -y title.mpg

For an NTSC source, use:

ffmpeg -i VTS_01_1.VOB -target ntsc-vcd -y title.mpg

The -target preset selects the VCD frame size, frame rate, MPEG-1 video settings, 44.1 kHz audio, and approximately 224 kbps audio. If the input contains multiple audio or subtitle streams, select the desired streams explicitly with options such as -map 0:v:0 -map 0:a:0; VCD does not preserve DVD menus, subtitles, or multiple DVD audio tracks.

2. Create a VCD 2.0 image with:

vcdimager -t vcd2 -c disc.cue -b disc.bin title.mpg

3. Open disc.cue in CD-burning software that supports BIN/CUE images and burn it to a blank CD-R at a moderate speed. Do not burn title.mpg as a normal data disc when compatibility with standalone VCD players is required.

Quality, compatibility, and limitations

VCD is a lossy downgrade from DVD: MPEG-2 video is re-encoded to MPEG-1 at roughly one quarter of DVD’s normal pixel count. Re-encoding an already compressed VOB can introduce block artifacts, softness, and motion smearing; increasing the output bitrate does not restore lost detail and makes the result non-standard.

Choose PAL or NTSC according to both the source and the playback equipment. Converting between standards requires frame-rate and often field-order conversion, which can create judder or interlacing artifacts. Test the generated MPEG before burning, and use VCDImager’s validation errors to identify files that do not meet the required limits.
