1080 30p footage going to DVD & BD advice?

Hi everyone,

Ive got a wedding shot in 1080 30p (but I actually edited it on a 720 30p timeline to allow for reframing) and I'm wondering what are the best ways to go to DVD and Blu Ray with it? I'm using premiere pro cs5 and encore cs5. Future projects will likely be edited as 1080 so my question really is the best way to go from 1080 30p to BD and DVD.

I tried the following tests so far. I exported the DVD intended videos as .avi and the BD intended videos as h.264. The last step will be authoring with encore which I have not done yet.

DVD 480 60i lower field. Seems to work.

DVD 480 24p. Plays choppy if there is hardly any motion.

BD 720 60p seems to work pretty well.

BD 720 24p. Plays choppy if there is motion.

BD 1080i 29.97. Upper. Hardware scaled with matrox acceleration.Seems to work much smoother than the 24p
tests.

So I'm wondering, I see an export option in premiere called "use frame blending" which I have never used. Would that help my 24p issues or can you not go from 30p to 24p smoothly?
 
You never want to convert 30p to 24p. It will always be choppy, as you've found.

30p plays nicely in 1080/60i (which is the same as 1080i "29.97") or 720/60p. Your only option for standard DVD is 480/60i.

Do NOT use frame blending. (That would make the conversion to 24p even worse by adding severe ghosting, BTW.)
 
Thank you, David Jimerson.

I appreciate the expert help.

So 1080 30p will work for DVD as 480 60i.
It will work for Blu ray as 1080i (60i / 29.97).

Plus it will work for Internet demos.

I'm trying to decide how to shoot in the future and that helps me out.
Was shooting all 720 60p but for some really scenic locations I wanted to make max use of the image with 1080.

I think we'll shoot 1080 30p for big scenic weddings, 720 60p for the basic ones and then with the one single camera we have that can do 1080 60p mix it with the others having the option of slow mo if needed.
Then for emergency low light weddings use 24p with a slower shutter if needed for more light.
 
That's really not the way to be picking your frame rates. You should be picking them because they have the motion you want. If you want things to look live, choose the faster frame rate. If you want things to have a cinematic feel, choose the slower frame rates. Or, for whatever artistic reasons you decide you want.

Same for your shutter speed. You shouldn't use it as an exposure tool, because it affects your motion blur. Choose a shutter speed because it gives you the image you want.
 
You are right, David.

Thank you for reminding me. What happens is Im so overworked and tired that I switch from the natural creative side of my brain to the other side and focus too much on the technical stuff like dealing with problems, limitations, environment and etc.
I don't want to get too sidetracked that the artistic side takes a back seat.

Thank you for helping me with the frame rates so I know what my delivery options are for the different ways the footage
is shot.
I like the way 30p looks and since all of my wedding clients currently want DVDs I may do more of it.
