What quality should I expect from the VOB output?

Our converter preserves as much fidelity as DVD Video Object allows. Where Flash Video carries information that DVD Video Object 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 FLV to VOB conversion change my video resolution or frame rate?

No. By default we preserve the original resolution, aspect ratio, and frame rate from your FLV source. Only the container and, where required, the codec changes. If your source uses a codec that DVD Video Object 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 VOB output?

The output size depends on the content and the compression characteristics of DVD Video Object. In most cases the VOB file will be in the same ballpark as your FLV 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 FLV to VOB instead of staying with FLV?

Convert when the application, device, or workflow you are targeting prefers DVD Video Object over Flash Video. If your current FLV 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 VOB), distribution (recipients expect VOB), or feature requirements specific to DVD Video Object.

What is the maximum FLV file size I can convert?

MegaConvert accepts FLV files up to 100 MB on the free service, which is enough for the vast majority of real-world Flash Video 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 FLV file safe and private when I upload it?

Yes. Your FLV 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 FLV to VOB?

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

Converting Flash Video to DVD Video Object 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.

Flash Video has a known limitation: obsolete format since Adobe Flash Player reached end-of-life in 2020. In contrast, DVD Video Object offers a key advantage: standard format for DVD-Video ensuring universal DVD player compatibility. While Flash Video is commonly used for legacy web video archives and content migration, DVD Video Object is better suited for dvd-video disc content storage and playback.

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

How to Convert FLV to VOB

Follow these simple steps to convert your file in seconds.

Upload your FLV video
Choose your .flv 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 VOB conversion
Click convert. Where the video codec is compatible with DVD Video Object, 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 .vob file
When the conversion finishes, click the download link to save the new DVD Video Object 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 FLV to VOB

Practical advice to get the best results from this conversion.

Why this conversion is worth doing

Flash Video has a known limitation: obsolete format since Adobe Flash Player reached end-of-life in 2020. DVD Video Object addresses this with a key advantage: standard format for DVD-Video ensuring universal DVD player compatibility. Converting from FLV to VOB 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

Flash Video is most commonly used for legacy web video archives and content migration, while DVD Video Object is the standard for dvd-video disc content storage and playback. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where FLV is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.

Watch for this limitation in the VOB output

DVD Video Object has its own limitation worth understanding before you commit: mPEG-2 video compression is inefficient by modern standards. After the conversion completes, open the VOB 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 FLV and VOB Formats

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

Source Format

Flash Video

video/x-flv

FLV (Flash Video) is a container format that was used to deliver video content over the internet via Adobe Flash Player. It typically contains video encoded with Sorenson Spark or VP6 codecs and audio in MP3 or AAC format. FLV was once the dominant web video format but became obsolete after major browsers discontinued Flash Player support in 2020.

Advantages

Compact file sizes with acceptable streaming quality
Simple container structure that is quick to parse
Large existing archive of legacy web video content

Limitations

Obsolete format since Adobe Flash Player reached end-of-life in 2020
No modern browser supports FLV playback without third-party tools
Limited codec support compared to modern containers like MP4

Common Uses

Legacy web video archives and content migration
Converting old Flash-based video content to modern formats
Historical video content from early streaming platforms

Target 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
