What quality should I expect from the TS output?

Our converter preserves as much fidelity as MPEG Transport Stream allows. Where DVD Video Object carries information that MPEG Transport Stream cannot represent, that information is mapped to the closest equivalent (for example, color spaces, codec parameters, or metadata fields). For most everyday uses the result is indistinguishable from the source.

Does the VOB to TS conversion change my video resolution or frame rate?

No. By default we preserve the original resolution, aspect ratio, and frame rate from your VOB source. Only the container and, where required, the codec changes. If your source uses a codec that MPEG Transport Stream cannot store, the video stream is re-encoded to a compatible codec while keeping the visual properties identical.

What file size should I expect for the TS output?

The output size depends on the content and the compression characteristics of MPEG Transport Stream. In most cases the TS file will be in the same ballpark as your VOB input, with differences driven by how each format encodes data. There is no fixed ratio — the converter does not change quality settings unless you ask it to.

When should I convert VOB to TS instead of staying with VOB?

Convert when the application, device, or workflow you are targeting prefers MPEG Transport Stream over DVD Video Object. If your current VOB file already opens and behaves correctly everywhere you need it to, there is no benefit to converting — keep the original. The most common reasons to switch are compatibility (a tool only accepts TS), distribution (recipients expect TS), or feature requirements specific to MPEG Transport Stream.

What is the maximum VOB file size I can convert?

MegaConvert accepts VOB files up to 100 MB on the free service, which is enough for the vast majority of real-world DVD Video Object files. If you have a larger file (typical for high-resolution video or uncompressed audio), please contact us — we can sometimes accommodate larger uploads for legitimate use cases.

Is my VOB file safe and private when I upload it?

Yes. Your VOB file is uploaded over HTTPS, processed in an isolated job environment, and deleted from our servers within one hour. We do not read, index, store, or share the contents of your file. No account is required, so the upload is not associated with a personal identity. See our privacy policy for the full details.

Why Convert VOB to TS?

Understand when and why this conversion makes sense for your workflow.

Converting DVD Video Object to MPEG Transport Stream is often necessary to ensure playback compatibility across media players, operating systems, and streaming services. Video formats encode footage using different codecs, container structures, and compression techniques, each with distinct trade-offs between file size, quality, and support. From sharing videos online to preparing files for professional editing workflows, the right format makes a significant difference in how your content is experienced.

DVD Video Object has a known limitation: mPEG-2 video compression is inefficient by modern standards. In contrast, MPEG Transport Stream offers a key advantage: robust error recovery designed for unreliable transmission channels. While DVD Video Object is commonly used for dvd-video disc content storage and playback, MPEG Transport Stream is better suited for digital television broadcasting (dvb, atsc, isdb).

With MegaConvert, you can convert VOB to TS online without installing software, preserving your video content accurately within the target format's specifications.

How to Convert VOB to TS

Follow these simple steps to convert your file in seconds.

Upload your VOB video
Choose your .vob file using the file picker or drag it into the upload area. Video uploads can take a few seconds for short clips and longer for high-resolution footage; the progress bar shows upload status separately from conversion. Files up to 100 MB are supported.
Start the TS conversion
Click convert. Where the video codec is compatible with MPEG Transport Stream, the stream is repackaged without re-encoding to preserve original quality. Where re-encoding is required, we use industry-standard codec presets that balance file size against quality. Audio tracks are converted in parallel.
Wait for the video conversion to complete
Video conversions take longer than other file types because video data is much larger. A short clip might finish in 10 seconds; a 100 MB file may take a minute or two depending on whether re-encoding is required. The progress bar shows the percentage complete.
Download your .ts file
When the conversion finishes, click the download link to save the new MPEG Transport Stream file to your computer. The file is yours — no watermarks, no expiration on the file itself, and no MegaConvert account is required to download it.

Tips for Converting VOB to TS

Practical advice to get the best results from this conversion.

Why this conversion is worth doing

DVD Video Object has a known limitation: mPEG-2 video compression is inefficient by modern standards. MPEG Transport Stream addresses this with a key advantage: robust error recovery designed for unreliable transmission channels. Converting from VOB to TS is most worthwhile when this specific trade-off matters for the way you intend to use the file.

Match the format to the actual workflow

DVD Video Object is most commonly used for dvd-video disc content storage and playback, while MPEG Transport Stream is the standard for digital television broadcasting (dvb, atsc, isdb). If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where VOB is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.

Watch for this limitation in the TS output

MPEG Transport Stream has its own limitation worth understanding before you commit: packet overhead results in slightly larger file sizes than MP4. After the conversion completes, open the TS file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.

Avoid transcoding unless necessary

Every time you transcode (re-encode) a video, some quality is lost unless you use a lossless codec. If you only need to change the container format without changing the codec, use a remux (stream copy) operation instead of a full re-encode. This preserves original quality and is much faster.

Understanding VOB and TS Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

DVD Video Object

video/dvd

VOB (Video Object) is the container format used on DVD-Video discs, containing multiplexed MPEG-2 video, audio (AC3, DTS, or MPEG), subtitles, and navigation data. Each VOB file typically represents a portion of the DVD content, with files limited to approximately 1 GB due to the UDF filesystem used on DVDs. VOB files can include copy protection data such as CSS encryption.

Advantages

Standard format for DVD-Video ensuring universal DVD player compatibility
Supports multiple audio tracks, subtitle streams, and navigation menus
Well-established format with decades of player and software support

Limitations

MPEG-2 video compression is inefficient by modern standards
CSS copy protection can prevent direct playback or conversion
Limited to DVD resolution (720x480 NTSC or 720x576 PAL)

Common Uses

DVD-Video disc content storage and playback
DVD ripping and backup operations
Legacy video archival from DVD collections

Target Format

MPEG Transport Stream

video/mp2t

TS (MPEG Transport Stream) is a container format designed for broadcasting and streaming MPEG video over unreliable or lossy media. It divides content into small fixed-size packets (188 bytes) with error correction capabilities, allowing decoders to resynchronize after transmission errors. TS is the standard container for digital television broadcasting, Blu-ray discs, and HTTP Live Streaming (HLS).

Advantages

Robust error recovery designed for unreliable transmission channels
Standard format for digital TV broadcasting and Blu-ray discs
Supports live streaming with HTTP Live Streaming (HLS) protocol

Limitations

Packet overhead results in slightly larger file sizes than MP4
Not ideal for local file storage where error resilience is unnecessary
Less convenient for editing compared to MP4 or MKV containers

Common Uses

Digital television broadcasting (DVB, ATSC, ISDB)
HTTP Live Streaming (HLS) video segments
Blu-ray disc video storage
