I purchased this device to do mostly videos. What would be the recommended sd memory card for doing video recording?
The Ellipsis is going to record the video on the internal memory; it will be up to you to move the video to the card after it's recorded. As large a a card as the tablet will support (I have a 32GB card in mine) is what I would recommend, as the tablet itself has little storage and you would need to move the videos frequently to keep the internal memory clear.
Thanks SuzyQ: What model of 32GB?
Currently in the tablet is a Verbatim Micro SD HC - I've used SanDisk Micros SD cards as well.
