EX-1 choice 1080/23.98 or 720/23.98
on Apr 26, 2009 at 1:38:30 am

Im setting up to shoot a cross country rally from LA to Miami. I want to shoot in 24p because I like the cinematic look that 24p gives. im leaning to 1080 because of the increased resolution. Am i wrong? i will deliver in 1080/29.97 so why even think about shooting in 720, aside from the over and under cranking?

Also, I've been reading the whole motion blur debate... I understand how 24 'looks', and I dont mind that. However, Im shooting moving cars all day and motion is everywhere... Any advice to a safe setting that delivers optimal clarity and minimal motion blur?

No, you're right. A 1080 image will look sharper on a true 1080 monitor than a blown up 720 image will.

You can under-crank in 1080 but not over-crank.

There are 2 shooting formats that will give you the best temporal resolution:

1080i 60 - 2 interlaced flields per frame
720p 60 - 2 complete pictures per frame

Anything else is a compromise between increased motion blur and the cinematic 'look'. You choose what's more important for the project. if you have your heart set on shooting 24p make sure you're doing it for the right reasons. Is your intent to sell this to someone afterwards? Do you have a buyer already? If so do they know you're going to shoot it in 24p?

The only way to reduce motion blur in 24p is to increase shutter speed/angle. Again, this is also a compromise because if you go too wild on the shutter you're going to get into the stuttery 'Private Ryan' look.

You need to get out there and shoot some test clips with the same sort of subject matter that the real project will be comprised of. See what shooting format and camera settings get the result you'll be happy with.

If you're going to deliver on film then I'd say go 24p.

But if you're going to deliver to anything on broadcast, then I would recommend shooting 30p and completely avoid potential pulldown issues. The difference of the look of 24p and 30p are probably not that significant. As suggested, do some tests and see.
