Canon 5Dii to 1080i?
 

Hello

I need to deliver 1080i for a client and I have the 5Dii.
Am I right that this camera can't deliver 1080i?

Does anybody know if there is a good way to convert the 1080p from the 5D into 1080i in the editing?
The client needs tv quality (I know that's a relative term, but I think you know what I mean).
