When you need MTS to AVI

MTS is the recording format of AVCHD camcorders: Sony, Panasonic, Canon, and others. Old devices do not understand it at all, and sometimes the only format they accept is AVI. Typical cases: an old TV without Smart TV reads only AVI from a USB drive, a car stereo with a screen plays clips only in this format, there is a DVD player with a USB port at home, or a familiar old video editor works with nothing but AVI.

Let us be honest up front: AVI is an outdated container. If your goal is simply to watch camcorder video on a computer, phone, modern TV, or to publish it online, choose MTS to MP4: MP4 is newer, more compact, and supported everywhere. Converting to AVI makes sense when a specific device or program understands only AVI.

What changes after conversion

The camcorder recording becomes an AVI file that opens on old hardware. The content is the same: your footage, the same sound. The video is re-encoded to fit the capabilities of the old container, so the file may turn out noticeably larger than the source or compressed less efficiently - that is a property of AVI, not a conversion error.

The quality of the result depends on the source: sharp camcorder footage stays as sharp as the playback device allows. Old TVs and car stereos often limit the picture resolution themselves.

When this is especially useful

  • An old TV reads a USB drive but only sees AVI - and you want to show camcorder recordings on it.
  • A car stereo with a screen plays clips only in AVI.
  • A DVD player with a USB port understands neither MTS nor MP4.
  • The old video editor you are used to accepts only AVI.
  • The video must go to someone with an old computer and a player that has not been updated in years.

What to check before converting

  1. Check the device manual for supported formats. If MP4 is on the list, choose MTS to MP4 instead - the result will be more compact.
  2. Check the device's resolution limits: many old TVs and car stereos will not play files above a certain frame size.
  3. Make sure the source file was copied from the camera in full and opens in at least one player.
  4. Convert one file first and test it on the target device before processing the whole archive.

Format and conversion limits

AVI was created in the early 1990s and falls short of modern containers: it handles modern compression poorly, lacks features like chapters and multiple subtitle tracks, and files are usually larger at comparable quality. On top of that, AVI support varies between old devices: every TV and car stereo understands its own set of compression variants, so compatibility with a specific model is not guaranteed. If a file does not play, check the device requirements in its manual.

The result depends on the source: conversion does not repair recording defects. Free access covers a one-off task; paid plans are available for a large archive - current terms are on the pricing page.

Related tasks

For watching on modern devices, sending, and publishing, choose MTS to MP4 - that is the main scenario for AVCHD camcorder recordings.

What is MTS to AVI conversion used for

Watching on an old TV

A TV without Smart TV reads only AVI from a USB drive - camcorder recordings convert and play without any extra equipment.

Video in a car stereo

A head unit with a screen accepts only AVI - converted camcorder clips play from a USB drive on the road.

DVD player with a USB port

An old player understands neither MTS nor MP4 - AVI from a USB drive opens and plays on the TV through it.

Old video editor

The familiar editing program does not import MTS - after converting to AVI the material opens and edits.

Tips for converting MTS to AVI

1

First check whether MP4 would work

If the device supports MP4, choose it: the file will be more compact and compatibility with modern hardware better. Save AVI for devices that understand nothing else.

2

Test one file on the device

Before converting the whole archive, put one finished AVI on a USB drive and make sure the TV or car stereo plays it.

3

Look into the device manual

Old TVs and car stereos have limits on resolution and file size. Knowing them in advance saves you from converting twice.

4

Keep the camcorder originals

Do not delete the original MTS files: AVI is a format for one specific old device, and the source will still be useful for converting to MP4.

Frequently Asked Questions

When should I choose AVI and when MP4?
AVI - only when a specific device or program understands nothing else: an old TV, a car stereo, a DVD player with USB, an old editor. In every other case MP4 is better - more compact and supported by all modern devices.
Why is the AVI file larger than the original MTS?
AVI is an old container with less efficient compression. For the video to play on old hardware, it is encoded differently from the source, and the file often grows in size. That is a property of the format.
Will the AVI work on my TV or car stereo?
Old devices support AVI differently: each understands its own set of compression variants and resolution limits. Convert one file and test it on the device. If it does not play, check the video file requirements in the manual.
Will quality be lost when converting MTS to AVI?
The video is re-encoded, and the result depends on the source. A noticeable loss of sharpness is more often caused by the playback device: old screens lower the picture resolution themselves.
Will the sound of the recording be kept?
Yes, the audio track is carried over to AVI. If the camcorder recording had several tracks, the main one ends up in the result.
Can I convert several camcorder files at once?
Yes, you can upload multiple files - each is processed separately. But first test one finished file on the target device.
What should I do if a file does not convert?
Check whether the source opens in any player and whether it was fully copied from the camera memory card. A damaged or partially copied file cannot be processed.
