most of the time yes, you can change the settings to record SD video, if not you can always convert the footage on your computer.
There are a number of ways to convert SD video into an HD format. The simplest is to display it on an HD television. All televisions have converters or resize engines that will convert the incoming resolution to the native resolution of the screen. This is necessary in order to fill the screen with the image and it takes place whenever the video source is a different resolution to the screen resolution. There are hardware and software based converters to enable live video to be converted into an HD format or video files to be processed into HD. Before doing so, bear in mind that converting SD video into an HD format will absolutely not create HD quality. The amount of detail in an image is limited by the resolution. If the image has been created as SD, increasing the number of pixels used to generate the image will not increase the amount of detail but it will spread the original detail across more pixels. If the plan is to change SD material into HD quality, it's not going to work unfortunately. If it just to display on an HD television, let the television do a single conversion to the required resolution.

That means that the processor needs to transfer many pixels in little time. The chance that the processor gets overloaded is higher than an SD vid. But with a good processor and graphics card this wouldn't happen ;-)
