This question addresses the fact that DSLRs have limits on video recording time and provides some speculation as to why the limit exists. It mentions that Canon has a 30 minute limit.
I am recording HD video on a Canon PowerShot ELPH 300 HS point-and-shoot, and am coming up against a 10 minute limit. This site says that there is a 60 minute limit on standard definition and 10 minute limit on high definition. With 720p a 10 minute video is about 1.5 Gb. I wanted to mention the 10 minute limit explicitly because it seems that many people talk about a 30 minute limit and so this seemed like a somewhat unique case.
My question is whether there is a way to extend the limit from 10 to something like 30 minutes? 10 minutes is just short for my purposes of recording my own judo tournament matches.
I guess it would have to be some kind of patch to the firmware. Does such a thing exist?
