What quality should I expect from the M2TS output?

Our converter preserves as much fidelity as Blu-ray MPEG-2 Transport Stream allows. Where WMV Video carries information that Blu-ray MPEG-2 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 WMV to M2TS conversion change my video resolution or frame rate?

No. By default we preserve the original resolution, aspect ratio, and frame rate from your WMV source. Only the container and, where required, the codec changes. If your source uses a codec that Blu-ray MPEG-2 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 M2TS output?

The output size depends on the content and the compression characteristics of Blu-ray MPEG-2 Transport Stream. In most cases the M2TS file will be in the same ballpark as your WMV 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 WMV to M2TS instead of staying with WMV?

Convert when the application, device, or workflow you are targeting prefers Blu-ray MPEG-2 Transport Stream over WMV Video. If your current WMV 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 M2TS), distribution (recipients expect M2TS), or feature requirements specific to Blu-ray MPEG-2 Transport Stream.

What is the maximum WMV file size I can convert?

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

Yes. Your WMV 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 WMV to M2TS?

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

Converting WMV Video to Blu-ray MPEG-2 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.

WMV Video has a known limitation: proprietary format with poor cross-platform compatibility. In contrast, Blu-ray MPEG-2 Transport Stream offers a key advantage: preserves full Blu-ray quality including HD video and lossless audio. While WMV Video is commonly used for legacy windows video libraries and media collections, Blu-ray MPEG-2 Transport Stream is better suited for blu-ray disc content backup and playback.

With MegaConvert, you can convert WMV to M2TS online without installing software, preserving your video content accurately within the target format's specifications.

How to Convert WMV to M2TS

Follow these simple steps to convert your file in seconds.

Upload your WMV video
Choose your .wmv 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 M2TS conversion
Click convert. Where the video codec is compatible with Blu-ray MPEG-2 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 .m2ts file
When the conversion finishes, click the download link to save the new Blu-ray MPEG-2 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 WMV to M2TS

Practical advice to get the best results from this conversion.

Why this conversion is worth doing

WMV Video has a known limitation: proprietary format with poor cross-platform compatibility. Blu-ray MPEG-2 Transport Stream addresses this with a key advantage: preserves full Blu-ray quality including HD video and lossless audio. Converting from WMV to M2TS 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

WMV Video is most commonly used for legacy windows video libraries and media collections, while Blu-ray MPEG-2 Transport Stream is the standard for blu-ray disc content backup and playback. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where WMV is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.

Watch for this limitation in the M2TS output

Blu-ray MPEG-2 Transport Stream has its own limitation worth understanding before you commit: very large file sizes due to high-bitrate Blu-ray encoding. After the conversion completes, open the M2TS 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 WMV and M2TS Formats

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

Source Format

WMV Video

video/x-ms-wmv

WMV (Windows Media Video) is a proprietary video compression format developed by Microsoft, based on the Advanced Systems Format (ASF) container. It was designed for streaming and local playback on Windows platforms and includes built-in DRM support for content protection. WMV has largely been superseded by H.264/MP4 for most modern use cases.

Advantages

Good compression efficiency, especially at low bitrates
Native support in Windows Media Player and Windows ecosystem
Built-in DRM support for protected content distribution

Limitations

Proprietary format with poor cross-platform compatibility
Not supported on iOS, many Android players, or web browsers without plugins
Declining usage and relevance in modern video workflows

Common Uses

Legacy Windows video libraries and media collections
DRM-protected video content from older platforms
Windows-based screen recordings and presentations

Target Format

Blu-ray MPEG-2 Transport Stream

video/mp2t

M2TS (MPEG-2 Transport Stream) is a container format used for Blu-ray discs and AVCHD camcorders, based on the MPEG-2 Transport Stream standard with additional Blu-ray-specific extensions. It stores high-definition video (H.264, VC-1, or MPEG-2) with lossless or lossy surround sound audio. M2TS files preserve the full quality of Blu-ray disc content including multiple audio and subtitle tracks.

Advantages

Preserves full Blu-ray quality including HD video and lossless audio
Supports multiple audio tracks including Dolby TrueHD and DTS-HD Master Audio
Standard format for AVCHD camcorders widely used in prosumer video

Limitations

Very large file sizes due to high-bitrate Blu-ray encoding
Not directly streamable or playable in web browsers
Requires capable hardware or software for smooth playback of high-bitrate content

Common Uses

Blu-ray disc content backup and playback
AVCHD camcorder recording format
High-definition video archival with full quality preservation
