Why convert M2TS to FLV?
- Conversion is useful when the destination has a strict format requirement.
- A converted copy keeps the original file intact for comparison and future edits.
- 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.
Will quality change?
The video is re-encoded into FLV, 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.
- Quality controls
- Options can adjust output dimensions, audio bitrate.
The file is processed on the server because the conversion requires a server-side engine or a utility operation.
- M2TS features without a direct FLV 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 FLV 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
- Do not overwrite the source; keep both versions until the output has been approved.
- Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
- If the file contains sensitive data, review the processing model before uploading it to a server.
Frequently asked questions

- Will quality change?
- The video is re-encoded into FLV, 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.
- Does the file leave my device?
- Yes. This conversion uses a server-side engine, so the file is uploaded over HTTPS, processed in an isolated request, and removed after the result is produced.
- Is batch conversion supported?
- Queue multiple files, run them together, and download the finished results as a ZIP. Each server file is limited to 100 MB, and large batches may take longer.
- What should I check before using the output?
- Open the downloaded FLV file in the application or database you plan to use, check the structure against the source, and keep the original until the output is approved.
