How do I record video for more than 30 minutes at a time with a Canon A1400 PowerShot?

Question

I'm planning to send a Canon A1400 PowerShot to the edge of space with a weather balloon (we will figure out how to keep the temperature in our payload box suitable, so that is not a pertinent issue to the question). Unfortunately I believe it can only record 30 mins/4GB of 720p at a time. Our flight's duration is 3 hours and we want to capture all of that.Can I program the A1400 with CHDK to recursively capture video till the memory card fills up? That is, start recording another video (almost) right after the 30 mins/4GB design limit is reached. If so, I would appreciate a script for the same!

Answer 1

I know that the AVCHD format, used by Panasonic Lumix (and possibly others) has no file size limitation, as I've personally used it to record events lasting up to four hours. I would suggest switching from MP4 or .mov to AVCHD if you have that option.
