Re-wrapping MTS footage as AVI is what makes it playable and editable outside the device or era it came from, without re-shooting anything. AVI (Audio Video Interleave) earns its place here: rock-solid legacy compatibility with older Windows software and hardware. MTS files come off Sony, Panasonic and Canon AVCHD camcorders. The picture quality is excellent; the container is awkward for everything except dedicated editors.

Picture and sound are re-encoded into the AVI container at a bitrate chosen to keep the result visually close to the MTS source. Resolution, frame rate and duration are preserved; file size usually changes noticeably because MTS and AVI lean on different codecs. Multiple audio tracks or chapter data may not carry over.
What you gain with AVI: Rock-solid legacy compatibility with older Windows software and hardware.
Drop your MTS file above and Morphio decodes it locally, then re-encodes it as AVI using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Free supports batches of 5 files; Pro supports batches of 250, subject to your device's memory. See exactly how in-browser conversion works.
Open the MTS to AVI 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 MTS data never leaves your device and no server ever receives a copy.
Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting MTS to AVI only rewrites the container and encoding you asked for — the source file on your disk is never modified.
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.
Morphio decodes the MTS file at full fidelity and re-encodes it at a high-quality AVI setting, so the difference is normally invisible or inaudible. What conversion cannot do is recover detail the original MTS file already threw away.
Yes — Free supports batches of 5 files and 10 conversions per day; Pro supports batches of 250 with no daily conversion cap. Your device's memory can impose a lower practical limit. Only usage counts reach the server, never files.
No. The conversion runs entirely inside your browser, so the file never leaves your device. The page and the required decoder must load first; free usage-limit checks may require a connection.
