I am recording 15-minutes videos with my GoPro Hero 3 Black edition. The camera starts a new file every 10 minutes of recording by default. I do not think I can change this in a setting.

When I do the white-balance and other edits in the GoPro Cineform Studio, I cannot find a function to stitch these videos back together into one continuous clip.

I was somehow expecting that if GoPro automatically splits these videos that there would be a function to rejoin them, too. Am I missing something? Is there such a function in this software or do I have to get another software to do this?

If so, what software should I get, assuming that I do not want to do anything else than that?

For this purpose I like to use SolveigMM Video Splitter. It's very fast and lossless video tool (no recompression) and it fully supports H.264 video (GoPro records in mp4 files using h.264 compression).

Cineform can't join clips together.

You could use iMovie (free), QuickTime 7 Pro (£30/$20), or something like Final Cut or Premiere (more).

You don't need Quicktime Pro to do this, the free version of the Quicktime Player can stitch videos as well. – Saaru Lindestøkke Aug 6 '13 at 13:12

If you are using PC, you have some great options. Avidemux is great and allows you to join separate clips together losslessy which is great. You simply open the first 10-minute movie clip in Avidemux and then choose "Append" from the File menu. Select your second clip and press OK. It should now simply be added onto the end of your first clip. Rinse and repeat for extra segments you might have. Make sure the audio/video options on the left hand side says "copy" or "stream copy" to ensure you are saving the new output file without re-encoding.

Virtualdub is also capable of this but you might need to install codecs/plugins to be able to open and use your files.

Hope that solves your problem!

The latest version of Cineform can join clips together as I found out recently, so the problem solved itself.
