MTS camcorder input

MTS commonly stores AVCHD recordings from cameras and camcorders in an MPEG transport stream. The browser must support the video and audio codecs inside the selected clip.

One clip at a time

This tool converts one .mts file and does not reconstruct an AVCHD folder, preserve camera menus, or combine sequential clips.

MP4 for compatible playback

Readable video is encoded as AVC and supported primary audio as AAC. Check the whole MP4 for interlacing, sync, duration, picture, and sound.

Private processing

The selected video is read and processed in this browser with MediaBunny. This workflow does not upload the video to an Instasize processing server.

MP4 output

Completed edits download as MP4 files with AVC video and AAC audio when audio is retained. Re-encoding can change file size and visual quality.

Browser limits

Codec support, speed, and memory limits vary by browser and device. Keep the original file and review the complete result before deleting or publishing anything.

Fast and Straightforward

Resizing photos for social media should be a cinch, but most editing programs are a pain to use. Of the dozen I’ve used, Instasize is the fastest, easiest and most consistent...
