    What changes when you convert AVI to MTS

    • The video stream has to be fully re-encoded: AVI typically carries MPEG-4 Part 2, and MTS expects H.264. That means a real transcode, so allow for processing time and a small generational quality cost.

    • At 1080p, AVI typically runs around 7 Mbps while MTS sits near 23 Mbps, which is the main driver of the size difference you will see.

    • This is an older container, introduced in 2006, and browsers will not play it directly. It is best suited to archival or a dedicated player.

    About AVI to MTS Conversion

    This page converts AVI video, stored in the RIFF AVI container since 1992, into MTS, which uses AVCHD and dates from 2006. The codecs each container accepts decide whether the picture has to be re-encoded.

    AVI comes from Microsoft and dates to 1992. It usually holds MPEG-4 Part 2, DivX, or Xvid video with MP3, PCM, or AC-3 sound, and those streams set the ceiling for anything converted out of it.

    MTS comes from Sony / Panasonic and dates to 2006. It holds H.264 video alongside AC-3 or LPCM audio, and every major platform needs a media player such as VLC to open it.

    After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.

    AVI to MTS: common questions

    Does converting AVI to MTS reduce audio quality?
    Only if the video has to be re-encoded. Where the codec carries across unchanged, quality is preserved.
    How much bigger or smaller will the MTS file be?
    It depends mostly on bitrate. AVI typically runs near 7 Mbps at 1080p and MTS near 23 Mbps, and size tracks that difference closely.
    Where can I play MTS files?
    Out of the box, no major platform plays MTS; viewers need a media player such as VLC. Choose it when the format itself is the requirement.
    What happens to subtitles and extra tracks?
    Embedded subtitle tracks are supported by MTS, so they can be carried across rather than discarded.
    Do I need an account to convert AVI to MTS?
    No. You can convert without an account, and a free account raises the size and length limits. Either way your file is used only to make the conversion, and the download link expires after one hour.
