AC130: 24P and Potential Hiccups

[tylerdlugolecki]

Hello-

So after six months with my first pro camera, AC130, I've become quite comfortable with the camera in regards to the tools, monitors, and effects. One aspect which I haven't fully explored yet is shooting at a framerate of 24P. I've been shooting events and sports so I've been switching between 720/1080 at 60p and 30p respectively. I haven't given 24p a go yet as I want to fully understand its limitations before I do. I have a wedding coming up and I feel that shooting at a 24p frame rate will allow me the look and feel I am after. I've decided that 720 will be the optimal resolution as I will be creating a standard DVD from the footage as well as be sharing it online.

After reading Barry's book, it is clear that for first timers, stobing may be an issue. Taking your time panning and sliding(just recently purchased a ZAZA) is essential in getting a great picture. I guess my first question is then about shutter speed. I'll be shooting in a church and then in a hotel for the reception. Should I set a shutter speed and leave it or will there be some times I may need to adjust? Strobing is probably my number one fear in shooting at this framerate.

2nd question: Does anyone recommend a scene file(either stock or from Barrys CD) that will work great for a wedding?

3rd question: Any other limitations I should be aware of? Is 24p more difficult to shoot in low light conditions?

4th question: I've recently heard people talk about shooting at a higher framerate (say 60p) and then dropping it in a 24p timeline. This confuses me. Does this make everything slow-mo? After increasing the playback speed of the clip does it give you a 24p look and feel or does it just mimic a fast paced 60 fps shot?

Thanks for any help you guys can pass along.

Tyler

Yes I use Filmic and bright from Barry's settings. Yes I caution you that if you do use 24fps to stabalize as much as possible becuase if you need to stabilze in post it is more difficult becuase there are less frames to work with... I tell you this based on my limited experience I'm sure someone here can explain the tech side of 24fps

While I don't do weddings, I've recorded a number of business functions and music events indoors at 24p, and have not noticed any strobing problem. These are events that don't have much movement in them with stationary speakers, musicians performing, etc.., and I've thus recorded with the shutter set to 1/24th. I would think that for a wedding ceremony, people would not be that actively moving around either. So I would bet that you could get by with 1/24th second for the shutter at the ceremony.

For the reception, though, I would try Barry's suggestion of 1/36th second for the shutter. For if you do have any quick movement when shooting at 1/24th second, you will most definitely see some noticeable motion blur.

I've been shooting in a shutter speed of 1/48 and haven't had any strobing issues but have also noticed that I don't seem to be getting as much out of the 24 fps effect as I could. I need to experiment more with 1/24 and 1/36 to see where the acceptable motion blur threshold might be.
