Video for iphone/ipad app

[Jeremy M Lundborg]

Throwing out a wide net for advice on shooting for an iphone/ipad app that will contain video.

 

First time I've attempted this and want the client to easily utilize the footage after we get done shooting, not confused as to where and why to crop or resize.

 

Looking at the aspect ratios in the photo attached, both are different but shouldn't require cropping or stretching with 5D video footage at 1920x1080 when used in landscape mode.

 

I don't have an iphone so any notes on how color responds and resolution differences would be helpful. Have you seen video on your computer screen and then your iphone and noticed a huge difference? Even the most basic things along those lines would be helpful.
