Frame Rate

[Kathy Smith]

Hi,

I'm shooting a live conference with XF305 and I am wondering about the frame rate. I think I would choose 60p, right? I normally shoot at 24p but that's when I'm making a movie but for a live conference I think 60p would be appropriate. Am I right? Any reason to shoot 60i?

Thanks
Kathy

24p would be fine for a live conference as well, 60i or 60p would be appropriate if you would have faster pans to follow a subject, like shooting a soccergame, so the general motion will be smoother. There is nothing wrong in shooting 60i either if your endproduct is dvd.

Thanks Noa

The end product will be web not dvd.
I won't be panning too much (at least I don't think I will). One camera will be a wide shot, so it won't change and the other camera will be a close up and I might be panning a bit and zooming in and out.
What is this shot at:

The frame rate discussion can turn into a religious argument very easily; be careful. ;-)

I tend to base my frame rate decision on what the final viewing platform will be. That said, both DVD and Blu-ray can handle 24p directly, that is, without 3:2 pulldown, as can most of the HDTVs they are attached to. Internet platforms don't tend to care much these days. Broadcast OTOH is the least flexible. Broadcast will apply 3:2 pulldown to 24p sources to get them up to 30p, which is then fairly easily transcoded into either 60i or 60p.

If you're not going to present it via broadcast, it doesn't much matter technically. Aesthetically it's a matter of personal preference.

That said, I can't see much to be gained by shooting a live conference at 60p. If the presentation is over the 'net, I'd probably shoot at 30p, if over DVD / Blu-ray, probably 24p. I can't imagine when I'd ever want to shoot anything interlaced.

Thanks Bruce, that's very helpful!
