The 600D/t3i has a video "clip" function that can shoot clips of short period (2, 4, 8 seconds each) and then prompts you to save them in a folder. This is a manual function that pops up after each clip is captured.
What would incredibly useful would be to be able to shoot an interval (say, the 8 second one, or even longer if it's possible to change it) and then have the camera automatically roll to a new file and keep shooting uninterrupted. There's a rough analog of this in the ML menus already in that if the camera stops due to time it can be told to roll over; adding the ability to have "clips" to do this has the potential to be very useful.
The utility of this feature comes with an EyeFi card -- now the camera has the ability to dump the video in real time provided it has a connection available, and if its fast enough it might even be able to keep up. If you could also specify the clip length up to a somewhat larger size (e.g. 1 minute) things would get even better.
Is this sort of enhancement a possibility?
