Why convert M2TS to FLV?

Re-wrapping M2TS footage as FLV is what makes it playable and editable outside the device or era it came from, without re-shooting anything. FLV (Flash Video) earns its place here: historic small-size streaming — today mostly a reason to migrate. M2TS is what Blu-ray discs and AVCHD camcorders write. It carries high-bitrate video with multiple audio tracks, but editors and browsers often stumble over it.

When M2TS → FLV is the right move

  • An editor, phone or TV plays FLV smoothly but stutters on M2TS — or refuses it outright.
  • You are uploading somewhere that lists FLV as a supported format and M2TS as unsupported.
  • Old M2TS footage needs to become something you can still open in five years.

Quality, size and what changes

Picture and sound are re-encoded into the FLV container at a bitrate chosen to keep the result visually close to the M2TS source. Resolution, frame rate and duration are preserved; file size usually changes noticeably because M2TS and FLV lean on different codecs. Multiple audio tracks or chapter data may not carry over.

How it works

Drop your M2TS file above and Morphio decodes it locally, then re-encodes it as FLV using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

M2TS to FLV — frequently asked questions

How do I convert M2TS to FLV without uploading the file?

Open the M2TS to FLV page, drop your video on the drop zone and press convert. Morphio runs an FFmpeg build compiled to WebAssembly that runs inside the page, so the M2TS data never leaves your device and no server ever receives a copy.

Does converting M2TS to FLV lose quality?

Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting M2TS to FLV only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the M2TS to FLV converter free, and how big can the file be?

Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.

Does converting M2TS to FLV lose quality?

Morphio decodes the M2TS file at full fidelity and re-encodes it at a high-quality FLV setting, so the difference is normally invisible or inaudible. What conversion cannot do is recover detail the original M2TS file already threw away.

Can I convert several M2TS files to FLV at once?

Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.

Are my M2TS files uploaded anywhere?

No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
