please forgive my complete camera ignorance but I recently picked up a canon elph P&S that shoots 720 HD video (after my wife lost both our P&S and camcorder in a Magic Kingdom bathroom)…was wondering if I need to get high speed SDHC cards to maximize video image quality or will the basic cards be fine?
thanks
I think you do best with the SD card Canon advises. It will be written somewhere in the user manual.
High Definition comes in a lot of different compressions. This means that the data transfer speeds are also really different, from 3Mbps to 300 Mbps. Most are in the lower region so mostly a 20Mbps will do fine.
