My Canon XA10 says it cannot use a SD memory card of 64GB or less to make movies. It must have 128GB minimum.

But my Sony VPCF1390X has only been tested and found compatible for 64GB memory cards. The HDD is 500GB. The Sony has SD memory card ports and a memory stick port.

I am looking for a way to transfer video from the Canon to the Sony for editing.

1. Will I need an external HDD?
2. Or will I be able to transfer directly from camera to computer with the firewire port?

Technical advice appreciated.
