Why convert MTS to AVI?
- The output can be tested in the destination workflow before the original is archived.
- A separate copy makes it easier to compare the old and new behavior.
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
Will quality change?
The video is re-encoded into AVI, so this is not a bit-for-bit copy. Resolution, bitrate, and codec support affect the final quality. The original source remains the best reference for comparison.
Processing and limits
- Processing
- Server-side
- Engine
- FFmpeg
- Maximum size
- 100 MB per file on the server.
- Batch support
- Yes, multiple files can be queued; completed results can be downloaded as a ZIP.

The file is processed on the server because the conversion requires a server-side engine or a utility operation.
- MTS features without a direct AVI equivalent may not survive the conversion.
- The output is re-encoded, so keep the original source as the archive copy.
- Browser-first paths depend on local codec support; unsupported cases fall back to the server.
Platform compatibility
The output is a AVI file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.
When not to convert
- Skip the conversion when the destination already accepts MTS and no compatibility problem exists.
- For a one-off preview, a local viewer may be faster than creating a new delivery file.
- If AVI support is uncertain on the destination device, test a sample before processing a large batch.
