SD Card speed

[robbo-79]

Hi guys I've just got a Samsung compact that is supposed to film in 720p but the footage I get is really jumpy, would this be due to the memory card write speed as if I lower the quality the footage is fine. I use a SanDisk Ultra II but see there are some faster cards albeit for a lot more money. Any advise gratefully received

you need to know the max write speed for your camera to know.
with out this info cant say what speed card would be best,
often putting too fast a card I seen test show it can slow the write up.
