Camcorder Videos That Won't Play Online?

You recorded important footage with your camcorder, but now you need to share it online. The problem: MTS files from AVCHD camcorders don't work directly in web browsers or on most video hosting platforms.

WebM is the answer. Developed specifically for the web, WebM plays natively in Chrome, Firefox, Edge, and Opera without any plugins. Converting your MTS footage to WebM makes it instantly shareable on websites, in emails, and across social platforms.

How to Convert MTS to WebM

  1. Upload your MTS file - Drag and drop your camcorder footage or browse to select
  2. Choose WebM output - Select WebM as your target format for web compatibility
  3. Download your video - Get your web-ready file in seconds

No software installation required. Everything happens right in your browser.

Why MTS Needs Converting

MTS (MPEG Transport Stream) is the format used by AVCHD camcorders from Sony, Panasonic, Canon, and others. While it captures excellent 1080p HD video, the format has compatibility limitations:

  • Browser playback - No web browser supports MTS natively
  • Video platforms - Many sites reject or poorly handle MTS uploads
  • File size - MTS files are larger than necessary for web streaming
  • HTML5 video - MTS cannot be used in website video players

In our testing, a 5-minute MTS clip at 1080p averaged 800MB. The same footage converted to WebM came in at around 150MB with visually identical quality.

WebM: Built for the Web

WebM was created by Google specifically for online video. It uses VP8 or VP9 video codecs with Vorbis or Opus audio, all royalty-free and open source. Here's why it matters:

  • Universal browser support - Works in Chrome, Firefox, Edge, Opera, and Safari (with some versions)
  • HTML5 native - Drop directly into website video tags
  • Efficient compression - Smaller files without visible quality loss
  • Fast streaming - Optimized for quick loading and playback

Common Uses for MTS to WebM Conversion

Personal Website Videos

Building a portfolio or personal site with video content? WebM is the go-to format for HTML5 video elements. Your camcorder footage becomes instantly embeddable.

Social Media Sharing

While platforms like YouTube accept various formats, converting to WebM first can speed up processing. For direct web sharing outside major platforms, WebM ensures compatibility.

Video Presentations

Creating web-based presentations or documentation? WebM files embed cleanly and load quickly, making your camcorder footage presentation-ready.

Quality and File Size

Converting from MTS to WebM typically reduces file size by 70-80% while maintaining visual quality. The VP9 codec in WebM is highly efficient at preserving detail even at lower bitrates.

Your original 1080p resolution is preserved. Colors, sharpness, and motion remain faithful to the source. The main difference you'll notice is how much faster the file uploads and streams.

Alternative Formats

WebM is ideal for web use, but consider these alternatives for specific needs:

  • MTS to MP4 - Better for mobile devices and universal compatibility outside browsers
  • MTS to MOV - Preferred for Apple ecosystem and Final Cut Pro editing
  • MTS to MKV - Best for archiving with multiple audio tracks or subtitles

Choose WebM when your primary goal is web publishing or browser-based playback.

Works on Any Device

Our converter runs entirely in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • No software to download or install

Your files stay on your device during conversion. Nothing gets uploaded to external servers.

Pro Tip

If you're embedding WebM videos on a website, always include an MP4 fallback in your HTML5 video tag for Safari users on older versions. The video element lets you specify multiple sources.

Common Mistake

Uploading raw MTS files directly to websites or embedding them in HTML. Browsers cannot play MTS natively, resulting in broken video players. Always convert to WebM or MP4 first.

Best For

Web developers embedding camcorder footage in websites, content creators publishing to custom platforms, and anyone sharing HD video via direct links rather than video hosting services.

Not Recommended

If you need to edit the footage in professional video software first, keep the original MTS or convert to a editing-friendly format like MOV or ProRes. WebM is optimized for playback, not editing workflows.

Frequently Asked Questions

MTS is the file extension for AVCHD (Advanced Video Coding High Definition) format used by camcorders from Sony, Panasonic, Canon, and other manufacturers. It records high-quality 1080p video but has limited compatibility with web browsers and online platforms.

WebM is specifically designed for web use and offers better compression for online streaming. While MP4 is more universally compatible across devices, WebM is the preferred format for HTML5 video elements and typically produces smaller files for the same visual quality.

Quality loss is minimal and typically imperceptible. WebM's VP9 codec is highly efficient at maintaining visual quality while reducing file size. Your 1080p resolution is preserved throughout the conversion process.

Expect file size reductions of 70-80% compared to the original MTS file. A 500MB MTS clip typically converts to a 100-150MB WebM file with visually identical quality.

WebM plays natively in Chrome, Firefox, Edge, and Opera without any plugins or additional software. Safari has partial WebM support in recent versions. For maximum compatibility, WebM is the standard choice for web video.

Yes, YouTube and most video platforms accept WebM uploads. However, these platforms also accept MTS directly and will convert it themselves. Converting to WebM first can speed up the upload and processing time due to the smaller file size.

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. The process happens locally in your browser.

Yes. The conversion happens entirely in your browser using local processing. Your video files are not uploaded to any external servers. Once you close the browser tab, no trace of your files remains.

The converted WebM file uses the Opus or Vorbis audio codec, both of which provide excellent sound quality at efficient file sizes. These codecs are fully supported by all browsers that play WebM video.
