what is the correct setting for 24p shutter speed on the HPX 300?

I know that you are supposed to double your shutter speed to 1/48 when shooting in 24P. But I don't see that as an option in the shutter menu on this camera.

Does the camera do it automatically when you set the camera to 24P ?

As an example, I have a Canon 5D and when I shoot in 24P I can get as close as 1/50 th shutter speed, the only thing I see as an option is 1/60th for the HPX 300.

Anybody know the answer ?

Thanks.
 
From the available shutter speeds shown in the menu it looks like 1/60 is as close as you can get. Shutter off gets you shutter = frame rate. Unfortunately they only give you one stop increments, not very flexible.
 
Ok thanks, I just wanted to make sure that there isn't some trick to adjusting it closer.
 
Presumably you can set the shutter to display in degrees rather than seconds, in which case 180 degree would give you 1/48th sec.

Thank you Mark and Steve I will try those suggestions and see what effect if any it has.
I really don't see a problem with it off I just recently learned about the1/48 rule and I'd like to try it and see what it does to the video. Thanks.
 
The problem with having the shutter Off is that you then get quite a bit of blur which can be unacceptable. Too fast a shutter speed and it's to storby.

As long as we're at it, has anyone figured out how to get the 300 / 370 into a manual WB mode? The Sony EX has the scrolling WB - where you can depress the WB button, scroll to the desired Kelvin temperature and then lock it in by depressing the WB button again.

I've found the +7 / -7 WB setting in the 300, but there must be a way to manually advance Kelvin?
 
erik - short answer is no.
you can do a white balance offset, but you can't dial it into a specific color temp.

carlos - change the shutter display to degrees and select 180 - that'll get you where you need to be.
 
From Adam Wilt's 370 review:
http://provideocoalition.com/index....sonic_ag-hpx370_1_3_3-mos_p2_hd_camcorder/P0/

"When the shutter is off, the shutter time is the inverse of the frame or field rate, e.g., 1/24 at 24fps.
This is perfectly normal for 60i video cameras, but those used to implementations on some other cine-oriented cameras might be expecting the default shutter speed at 24 fps to be 1/48—
and annoyingly there is no 180-degree shutter setting in the preset speeds; you have use synchro scan to dial it in.
It’s not a big deal, but it can slow things down a bit, especially because the synchro scan setting has a tendency to revert to 1/60 whenever modes or frame rate are changed. "

Looks like Brian's way should make it into Adam's review?
 
hi Steve,

I did see your post earlier and I said Thank you. I believe I have it now but I'm not sure, I didn't see a setting in the menu to change the shutter to degrees. The only thing I have been able to do is set the shutter to 1/60th and I used the syncro scan and dialed it to 180.3 If I recall correctly, it that how its done?
 
Carlos,
Go to MAIN MENU > 7.DISPLAY SETUP > SYNC SCAN DISPLAY > sec/deg... There you may select "deg"
You can reach the shutter degree angle values through the SYNCHRO SCAN +/- buttons on the left side of your camera...
Regarding shutter speeds, I agree absolutely with Adam Wilt. I have always used the corresponding speeds for 24p or 30p frame rates setting the shutter off and then selecting 1/60.0 variable default shutter to select 1/48 or as is, accordingly. Be adviced that after changing frame rates or shooting modes, the shutter speed will return to the 1/60 camera default speed...
Hope this helps.
Best.

Ok Henry, I found it and set it to 180 and it seemed a bit washed out, then I set it to 48 and the colors came back and I can see clearly the difference in blur.
I see the point the guys made earlier, one other thing I noticed was that the jello is much more noticeable especially when I shot of the shoulder.

I guess that again you would use this only in a very limited amount or in a traditional film style and let the movement happen in the frame and not the camera.

I have to check it out on a tripod and see what effect it has.

Great info guys Thanks.
