Shutter speed and angle question with AF100

I'm trying to be sure that I'm calculating my shutter speeds correctly with the AF100. I'm shooting at 24P. So, should be shooting with a shutter speed of 1/60? I've heard it said that you should be doubling my frame rate. So shouldn't that be 1/48th? The AF100 won't let me choose that shutter speed natively when i'm at 24p.

Also, I'm going to be shooting a polo match tomorrow with my AF100 and my 80-200mm Nikon zoom. Any thoughts on the shutter speed I should shoot at when at 24p? I will also be shooting some slow motion at 60p. I've shot some action shots in the past and am curious what shutter speeds are best for fast action in 24p and 60p on the AF100.

Thoughts?
 
Just set the camera to 180 degrees and you are all good. If you are outdoors it can be worthwhile trying to use a faster shutter speed when shooting faster moving stuff to preserve sharpness.
 
I will be shooting outdoors. I'll be shooting horses galloping. Any thoughts on what shutter speed to go to?

My experience is that with a faster shutter speed, say 90 degrees or 1/250 or 1/500, you will freeze the action but the result is very 'video' looking frames. I've been shooting a lot of action with a 270 degree shutter that tends to blur the edges but while in motion, it provides a more 'filmic' look at action. A frame grab will looked blurred but in motion it is very pleasing.

I would suggest doing a test of both shutter speeds and picking the one you like. Again, it's two totally different looks, especially @ 60fps.

Set the camera to 180 degrees, and then it will be always be double the frame rate at any frame rate (ie, 12fps will be 1/24, 24fps will be 1/48th, 30fps will be 1/60th, 60fps will be 1/120, etc).
 
At 24p I don’t go over 1/60. Since it’s a preset and it’s fast to dial it in, but in lower light 1/48 is money!

Fast shutter speeds are jarring and very unnatural looking. If slow motion capture is necessary shoot 48 or 60 FPS for those shots. Polo at high frame rates would be awesome!

I used to turn the shutter off but lately have been seeing a tad to much motion blur in moving objects or subjects.
 
And that's as close as you can get to 1/48 (or double the frame rate) on the AF. Although I would imaging 1/60 allows you to pan a bit quicker with less strobing.

Well, you can get exactly 1/48 if you want, you just have to use the Syncro Scan shutter.

Again a word of caution though, on this or any MOS-sensor camcorder, you have to be very careful when you change the shutter speed to anything but 1/60th (or 1/50th in PAL territories) and you're shooting under fluorescent or HMI or other ballasted light sources; using anything other than 1/60th can cause rolling bands in the footage.

Whenever I go to an Asian 220v country and shoot at 1/60 under fluorescents I feel like I get rolling bands. Should I just be experimenting with the synchro shutter to find the right speed?

No, that's exactly what will happen, and you have to use 1/50th when in those countries.

"shutter off" in an AF100 results in a shutter speed of 1/50 (when shooting 1080p).

Really (I am not doubting you, just a little surprised)? Is that at 24p or at 25p? On the HPX/HVX, I seem to remember shutter off was 180degree, resulting in 1/48th if you were at 24p, and assumed that it was the same on the AF100. I keep mine at 180degree setting as I like the piece of mind of seeing it say I am at 180degrees (so I know I did not leave it set on something else from a previous shot), so it makes no difference to how I shoot on a day to day basis, but I would like to know for the sake of knowledge.
 
"shutter off" has always been 1/50 on all the Panasonic AG series, excepting the HPX300/370 and HPX250. On those, "shutter off" is actually no shutter, so it'd be 1/24 on 24p and 1/25 on 25p.
 
Fluorescents with high speed ballasts, like Kinos, & HMIs with electronic ballasts, can be used with most any shutter speed/angle.

When in countries with 50 Hz juice I change the shutter angle to 172.8* for 24p.

So Barry, to clarify. Should I keep it at Shutter off for normal shooting situations? Or keep it dialed into 1/60th most of the time?
 
Depends on what lighting conditions you shoot under. If you're in daylight, then yeah, shutter off is fine, or just put it on 180 degrees and leave it there. But if you're shooting under magnetic fluorescents or magnetic HMIs, you simply MUST NOT use 'shutter off', you have to manually go in and set it on 1/60th.

So, for safety's sake and to not have to worry about it ever again, just put it on 1/60th and only ever change it when you know specifically what you're doing and why.

Awesome! Thanks Berry!

Also, I've been shooting a lot of 60P slow motion at 1/120 shutter. Would you recommend a faster shutter if your shooting fast sports? Or is 1/120 natural enough looking?
