Question for Barry Green
Barry,
Let me start by saying I am anxiously awaiting the arrival of your Bootcamp Series and Noah Kadner’s Panasonic P2 Workflow with Final Cut Pro and the HVX200.
100% of our work still winds up in 480i. Either on DVD or SD broadcast. However, we shoot everything in HD for future use with our HVX200. Other than 1080i 60 I haven’t found an HD format that doesn’t strobe when viewed on an NTSC CRT. I’d like to shoot in 720 30pn in order to take advantage of the smaller file sizes but I my clients complain about the strobing.
Here’s what I do. Using FCP v5.1.4 I edit my sequence using the 720 30p preset. I then export my finished sequence as a self contained movie. Then I import it back into my project. Next I create a new sequence using the DVCPRO 50 anamorphic preset with the field dominance set to lower (even.) Also, I set the motion rendering quality to best. I drop my self contained 720p 30 movie into it and render it. What am i doing wrong?
Below is the closet answer I could find to my question.

Subject: Re: 720p Vs. 1080iThree of the major US broadcasters are broadcasting 720p; the others are mainly broadcasting 1080i. Overall the market is something like 75% 1080i, 25% 720p. HVX lets you do both; pick the format that’s appropriate for the job you’re shooting.
1080/24p is better than 720/24p. 1080/30p is better than 720/30p. 720/60p is better than 1080/60i. But 720pN takes up half (or less than half) the storage space of 1080, so that has to be a factor.
For ultimate resolution and smoothest compression, 1080/24p or 1080/30p is my first choice. For best “reality” motion rendering, 720/60p is better than 1080/60i. For variable frame rates, you have to use 720.

Hi Robb,
Any FCP-related questions should go to Noah Kadner; I don’t use FCP.
Strobing is going to happen when you use a slower frame rate and move the camera too fast. That’s a given. 720/60P will be completely strobe-free (but will be larger file sizes, of course). If you want that glass-smooth look, you’re not going to get that with 30P. 30P is more like the film look, closer to 24P, and will give you strobier motion than 60P will.

Hi Robb-
You’ll see my recommendations on the DVD. I think 720p/24pN is the best format to use with the HVX200. And you should be cutting in HD then downconverting to SD when all is said and done. As for strobing- that’s kind of a subjective view of 24p in general and can be due to either inexperience with the format, too fast of panning along a scene or perhaps incorrect export settings.
