I notice that the format for the video my camera takes is not AVI or MPEG. The output video file is .mts (AVCHD).

Are there are free converters for this (to convert to AVI)?

After googling around the only software I can find is stuff you have to pay for.

There is MediaCoder, but you'll need to figure out the 'recipe' for conversion.
Here is one reference on its forums.


Have you tried VLC? If it can play it, it can transcode it.


As per YouTube help they accept the following video formats:

  • Windows Media Video(.AVI)
  • .3GP (mobile phones)
  • .WMV (windows)
  • .MOV (mac)
  • .MP4 (iPod/PSP)
  • .MPEG
  • .FLV (Adobe Flash)
  • .MKV (h.264)

Quickest way from .mts to YouTube is probably to use eac3to and then run with the following command paramaters:

eac3to input.mts output.mkv

See the Wiki for further info. Also, if you don't already have it you will need Haali Media Splitter
