Can't Play Your Camcorder Videos?

You recorded important footage with your Sony, Panasonic, or Canon camcorder, but when you try to play it on your computer, nothing happens. The files are in MTS format (also called AVCHD), and most media players don't support it natively.

Converting MTS to AVI solves this problem instantly. AVI is one of the oldest and most widely supported video formats - virtually every media player, editing software, and device can handle it. In our testing, AVI files played without issues on every system we tried, from Windows XP to the latest macOS.

How to Convert MTS to AVI

  1. Upload your MTS file - Drag and drop or click to select your camcorder footage
  2. Confirm AVI output - AVI is preset as the target format for maximum compatibility
  3. Download your video - Your footage is now ready to play anywhere

The entire process happens in your browser. No software to install, no accounts to create, no waiting.

Understanding MTS and AVCHD

MTS stands for MPEG Transport Stream and is part of the AVCHD (Advanced Video Coding High Definition) standard. Sony and Panasonic developed this format specifically for HD camcorders, and it's been widely adopted since 2006.

AVCHD records stunning 1080i/1080p video with excellent compression, but the format's complexity causes headaches:

  • Windows Media Player - Won't play MTS without codec packs
  • Video editors - Many programs import MTS poorly or not at all
  • Smart TVs - Hit or miss MTS support depending on brand
  • Social media - YouTube and most platforms reject direct MTS uploads

AVI, developed by Microsoft in 1992, remains universally compatible despite its age. It's a container format that works with virtually any codec, making it ideal for archiving and sharing footage.

When to Use MTS to AVI Conversion

Editing in Older Software

If you're using video editing software that struggles with MTS files, converting to AVI provides smooth import and timeline performance. Programs like older versions of Windows Movie Maker, Pinnacle Studio, and even some newer editors handle AVI more reliably.

Sharing with Others

When you need to share camcorder footage with someone and don't know their system specs, AVI is the safest choice. They won't need to install special codecs or players.

Archiving Footage

For long-term storage where future compatibility matters, AVI's widespread support means your videos will remain playable for years to come.

Playback Issues

If your computer stutters or freezes when playing MTS files, the conversion to AVI often resolves performance issues, especially on older hardware.

What About Quality?

Your video quality remains excellent after conversion. We process MTS files carefully to preserve the HD quality your camcorder captured. The AVI container supports high-quality video compression, so you won't see degradation in your footage.

File sizes may differ slightly depending on the codec used. In our testing, converted AVI files were comparable in size to the original MTS footage while maintaining visual fidelity.

Alternative Output Formats

While AVI offers maximum compatibility, other formats might suit specific needs:

  • MTS to MP4 - Better for web sharing and mobile devices
  • MTS to MOV - Ideal for Mac users and Final Cut Pro
  • MTS to MKV - Best for preserving all video features

Choose AVI when you need guaranteed playback on any system, especially older computers or Windows-based environments.

Works on Any Device

Convert MTS to AVI directly in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • No plugins or extensions required

Your files stay on your device throughout the conversion process. No uploads to external servers means your personal footage remains private.

Pro Tip

If your camcorder creates paired .mts and .m2ts files, the .mts files contain the actual video. Convert those. The folder structure (BDMV/STREAM) is for Blu-ray authoring and can be ignored for simple conversion.

Common Mistake

Trying to rename .mts files to .avi doesn't work - they're completely different formats that require actual conversion. Just changing the extension results in unplayable files.

Best For

Perfect for camcorder owners who need to play footage on Windows PCs, import into older video editing software, or share with recipients who might not have MTS codec support.

Not Recommended

Skip the AVI conversion if you're uploading directly to social media - MP4 is more efficient for web delivery. Also unnecessary if you're staying within the Sony/Panasonic ecosystem where MTS plays natively.

Frequently Asked Questions

MTS is a video file format used by AVCHD camcorders from Sony, Panasonic, Canon, and other manufacturers. It records high-definition video (720p, 1080i, or 1080p) using H.264 video compression and is commonly found when transferring footage from HD camcorders.

Windows Media Player doesn't include native MTS/AVCHD codec support by default. You'd need to install additional codec packs. Converting to AVI eliminates this problem since Windows has played AVI files natively since 1992.

No significant quality loss occurs. We use high-quality conversion settings that preserve the HD resolution and visual fidelity of your original camcorder footage. Both formats support high-quality video encoding.

Yes. Upload several MTS files and convert them all to AVI in a single batch. This is especially useful when processing footage from a full day of recording.

Both are AVCHD formats. MTS is typically used for video files on the camcorder's memory card, while M2TS appears on Blu-ray discs. The video content is identical - only the container differs slightly. Both convert to AVI the same way.

Nearly all video editing software supports AVI, including Adobe Premiere, Final Cut Pro, DaVinci Resolve, Vegas Pro, Windows Movie Maker, iMovie, and most free editors. AVI compatibility is essentially universal in video editing.

Conversion time depends on file size and your device's processing power. A typical 10-minute HD clip converts in 1-3 minutes on most modern computers. Processing happens locally in your browser.

AVI offers broader compatibility with older systems and editing software, while MP4 provides better compression for sharing online. Choose AVI for maximum playback compatibility, especially on Windows. Choose MP4 for web uploads and mobile viewing.

YouTube doesn't list MTS as a supported format. Converting to AVI (or MP4) first ensures your upload processes correctly. Many users report upload failures or quality issues when attempting to upload MTS directly.
