You probably all know this, but compatible SD memory cards should have a speed " Class 6 " or above for recording motion pictures. The speed class refers to a specification for sustained write speeds. I have a Panasonic Lumix TZ 18 which gave great still and motion results on my Philippines trip last month. However, before going I tried a " Class 4 " memory card which gave poor " jerky " motion pictures ( but good still pictures ). So I bought a SanDisk 8 GB 20 MB / s Extreme HD video SDHC card, " Class 10 ", through Amazon for 12.89 GBP. This allowed over 600 still pictures and 20 short motion pictures, with spare memory.
