Why Convert AVI to M2TS?
Understand when and why this conversion makes sense for your workflow.
Converting AVI 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.
AVI Video has a known limitation: no native support for variable frame rate or modern streaming features. In contrast, Blu-ray MPEG-2 Transport Stream offers a key advantage: preserves full Blu-ray quality including HD video and lossless audio. While AVI Video is commonly used for legacy video file storage and archival, Blu-ray MPEG-2 Transport Stream is better suited for blu-ray disc content backup and playback.
With MegaConvert, you can convert AVI to M2TS online without installing software, preserving your video content accurately within the target format's specifications.

How to Convert AVI to M2TS
Follow these simple steps to convert your file in seconds.
Upload your AVI video
Choose your .avi 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 AVI to M2TS
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
AVI Video has a known limitation: no native support for variable frame rate or modern streaming features. 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 AVI 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
AVI Video is most commonly used for legacy video file storage and archival, 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 AVI 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 AVI and M2TS Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
AVI Video
video/x-msvideoAVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows framework. It stores video and audio data interleaved together and supports a wide variety of codecs. While AVI is a mature and widely supported format, it lacks many features found in modern containers such as native streaming support and variable frame rates.
Advantages
- Very wide compatibility with both old and new media players
- Simple container structure that is easy to process
- Supports virtually any video and audio codec combination
Limitations
- No native support for variable frame rate or modern streaming features
- Poor subtitle and metadata support compared to MKV or MP4
- Older container design lacks advanced features like chapters
Common Uses
- Legacy video file storage and archival
- Video capture from older software and hardware
- Simple video editing and offline playback
Target Format
Blu-ray MPEG-2 Transport Stream
video/mp2tM2TS (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
