Re: Appropriate format usage

720p60 is good for fast motion because of the faster frame rate. That's why most sports are broadcast in this format.

1080i30 is good if there isn't a lot of motion, because you won't notice interlacing artifacts.

1080p24 gives a "cinematic" frame rate at HD resolution.

1080p60 is even better than 720p60 for the same reasons and is also good for slow-motion shots. But there is no ATSC standard for 1080p60, so over-the-air broadcasters can't use it unless it is conformed to 720p or 1080i.


I recommend you read up on resolution, frame rate, and interlaced/progressive footage. Once you understand these concepts, it's quite easy to understand the benefits and drawbacks of each format.
