Taking a look at the new iPad and seeing how it stacks up against the previous generation Air 2. No shocker that both are excellent tablets. But you may be a little surprised with this new iPad review. The 4k source video used for the iMovie export test is a 2min 13sec 100Mbps video shot using a Panasonic G7 (a great 4k cam btw). This video was shot on a Samsung NX500 All music was produced using samples from Samsung Soundcamp.
