This demo will show you how to import footage directly from the Canon 5D2 into the Ipad, edit the footage, and export out to your own FTP site uncompressed or various common sites like YouTube, Vimeo, Facebook, etc.
All this is possible with the iOS 5 and IMovie update that came out October 12, 2011 that expanded support for video imported from external DSLR cameras.
Update: Also, you can transfer video directly from your IPhone 4 to the IPad by connecting the Iphone charge cable to the Iphone – the USB end into the camera kit USB adapter – then plug that into your IPad. Follow the below procedure to transfer the file.
Here's what you need:
Ipad2 – with iOS 5 or later
Canon 5D2 with USB cable
IMovie 1.2.2 downloaded from the App store – $15
That's it – not much at all. For what I do it's better than carrying around a laptop plus you have connectivity via WiFi and Cellular if you need to feed the footage out quickly – the latter being most anywhere in the world these days.
To get started connect your Canon 5D2 to the Ipad using the USB cable and the Apple USB adapter. It's only USB (20MB/sec) but heck, maybe the Ipad3 will have a thunderbolt port and Canon will support it down the road – wouldn't that be great. But for right now USB2 is better than nothing – you just have to wait a little longer to transfer the video/still pics.
