How to convert MTS to AVI
- Add your .MTS file - drop it in the box above or click to browse.
- Convert it to .AVI in a few seconds.
- Download your new .AVI file.
What to expect
- AVI files are usually larger than equivalent
.mp4files - the container is less efficient, and some converters fall back to older codecs like MPEG-4 or DivX. - Audio from
.mts(Dolby Digital or PCM) is typically re-encoded to MP3 inside.avi, adding a lossy step that MP4 avoids. - 1080i footage from AVCHD camcorders will show combing artefacts unless you enable a deinterlace filter before converting.
Frequently asked questions
Will converting MTS to AVI reduce video quality?
Not if the output codec stays H.264 - the video stream is re-wrapped rather than re-encoded from scratch. Choosing an older codec like MPEG-4 or DivX will reduce quality.
Why is my AVI file larger than the original MTS?
AVI carries container overhead that MP4 avoids, and some tools default to less efficient codecs. Set H.264 explicitly in the output settings to keep file sizes comparable.
My converted video looks combed - what went wrong?
The source was likely recorded at 1080i, common for Sony and Panasonic AVCHD camcorders. Enable a deinterlace filter in your converter before exporting.
Should I convert MTS to AVI or MP4?
Convert to
.avi only if a specific legacy application requires it; .mp4 delivers the same video quality with smaller files and plays on virtually every device.Programs that convert MTS: Nero Multimedia Suite · Aimersoft iTransfer for Windows · ImTOO DPG Converter · WinX Video Converter · 4Free Video Converter · Free Studio · Freemake Video Converter · MediaCoder
