Movies clips with Canon or Sony

Dear all

I make excuses myself in the first place for my English.

I would want to buy a digital camera compact them in order to make underwater photo and video, therefore it serves me with relative underwater case.

I would be oriented to buy the Canon S60, because to how much I have seen is considered one of the best ones, but have a problem with the duration of the video clips. I explain myself better. Me it has been said, from Canon Italy, than the S60 it can only make three minutes of formed resumption 640x480 (is the top quality video? for 30fps what it is?), independently from the employed memory, 256-512 Mb is it or 1Gb; it would change only the amount of the video ones, not their temporal length. While, to said of the Service Sony Consumers, with the T1 the things change, with 256Mb I would have until ninety useful minutes of continuous resumption, and the double quantity if you used the 512.

True how much me has been said from the Sony, like is possible that there are such differences between the two firm? Resolutions to explain it to me in comprehensible terms for a neophyte like me?

To the end, which machine advised to me?

Thanks to anyone want to answer to me.

Ok, I think I get your question. You want to know why canon is limited to a 3 minute video clip, while sony lets you fill up the card with one continuous movie?

The reason for this is where the movie is stored while it is being recorded.

Canon stores the movie on an internal memory untill you are done and then it moves it to your removable memory card. The internal memory is small, it can only fit a 3 minute movie clip so after 3 minutes you must stop and let the movie be moved to the removable memory and then you can take a new movie.

Sony does not have the internal memory, it writes the movie onto the removable memory card directly while you are still filming so the only limitation of length is the size of your removable memory card.

So yes, it is true the sony is not limited in the length of its movie clips, while tie canon is. It has nothing to do with the resolution or quality of the movie, it has to do with where the camera puts the movie while it is being recorded.

For use underwater 3 minutes is a LONG movie. You probably will not ever need to take a movie longer than that underwater, but if long movies is a feature that you find important, the sony would be better for you.
