Animation for an app

Hello, I'm new to motion 5 (and animation) and am trying to work out what size, dimensions, resolution etc is best to make an animation for an app to be viewed full screen on an iPad/iPhone.

I need to know the best way to save the animation, ready to send to the developer.

I'm working with Photoshop .psd RGB files.

As yet I don't have FCP.

Any advice would be greatly appreciated.

Thanks,

Dan

I work with 720 30p, which looks really good on iPad and iPhone.

Many Thanks Ben.

I put the whole thing together as 720p30 first, then export that from Motion or FCP X, or transcode in Compressor for the Apple TV 1080 preset. It works on iPhones, iPads, and ATVs.

But if you're exporting to hand off for someone else to finish, keep it as ProRes.

Thanks, what dpi would you use for the .psd files?

No zoom & pan, the frame size of the video (1280x720). If zooming & panning, 2560x1440 (2x) and no larger.

There is no DPI in video, because no matter what, you're working with 1280 pixels horizontally and 720 pixels vertically, period. There are no "inches" to measure by.

Great help, many thanks Ben
