Simple "cuts only" AVCHD-capable software?
 

Has anyone come across a freeware or shareware app that can trim the ends off an avchd clip and output the selected portion as a new clip (without recompressing?).

Boilsoft's Video Splitter will do this for mp4 clips, but I haven't be able to get it working on mts clips.

Perhaps multiAVCHD, tsmuxer, or tsremux may be useful?

Indeed - thanks!

Not really freeware, but dont many cameras come with a simple app like that?

Not necessarily, when you buy one cheap on EBay :)

If you didn't get the software that came with the camera, you might be able to download it from the camera manufacturer's web site. If not, you might able to contact support and get it.

It's a Canon HF10, and the only Pixela software available for download from their site an update, which requires the base version to already be installed.

I believe it is available for purchase, but since the forum comments on the software are generally quite dire, I figured there might better alternatives. I also have a Samsung HMX-104 and a Creative Vado, which both produce h.264 footage, so one application that can handle all of them would be ideal.

Sounds like a good idea. Most of the software that comes with cameras is a bit on the "lean" side.
