I'm interested in using an iPad to edit video from my Mini 3 Pro, does anyone have any experience with this? I am also in the market for a new iPad, any advice on how much memory my iPad should have for editing purposes? Thanks in advance for any advice, I've researched this topic and found very little information.

Davici Resolve just got launched for the iPad.   It's worth a look and you can try it for free up to HD export.
