dvx100a 24p focusing

Hey everyone,

I did some searching and couldn't find the answer.

Is it hard to focus well using the DVX100 while in 24p?
Also, because of the jerkyness when filming in 24p, is it hard to film using it?

And, if I get an external LCD, will there still be jerkyness?

Thanks in advance.
 
i'd suggest manual focus regardless of 24p or not..
that way you can always get the things you want in foucs, and the things you don't, out of focus.
 
its no harder to focus in 24p than in 60i or any other mode.

personally I've never understood other people's issue with the "strobing" of 24p. It looks just like anything shot 24 frames a second. As far as difficulty, besides maybe taking a little more care with your pans and such, its really no more difficult.

and if you think it looks "jerky" in the viewfinder, than it will look jerky on an external monitor.

Not quite sure what you mean by it being "hard" to film using 24p because of strobing. Are you asking if it is possible to get no strobing while in 24p mode?

Basically, to get no strobing it should take 7 seconds for something to move across the screen. Practice makes perfect, but as cheesesailor says-If you need to pan fast, then the strobing is something that you'll need to put up with. The best thing to do would be to purchase Barry green's book and dvd on the dvx. You can find it through this site. That will give you all the info you need in regards to this camera.
 
To reduce the strobing effects, set your shutter speed to 1/24. This will lessen the strobing, at the same time give a bit of motion blur, which adds to a more "filmic" look. If that's the effect you're after.

I hate to post right after someone else while contradicting them but I can't agree less with shooting 1/24th having a more filmic look. Shooting 1/24the will give more motion blur, to the point that everything is blurry, if you like the blurry look go ahead and shoot at 1/24. Leaving the shutter speed set to "off" is the equivalent of a 180 degree shutter angle that is used in film cameras and for the most part every motion picture film being shot, except for special visual effects. If you are seeing excessive strobbing in your picture you are

A. Panning the camera too fast
B. Judging the picture based on what you see in the LCD screen and shooting 24PA footage
C. You are shooting 24PA or 24PN and your editor is removing the pulldown incorrectly.

Now I say excessive strobing becasue all film strobes more than 60i footage, which is what gives it a look closer to film. Another option would be to shoot 30P which will still maintain a more filmic look, but since your shooting at a higher frame rate you have more temporal information.

I've been shooting with the DVX, 16mm and HD cameras for several years (well not the HD cameras, just recently started using them) and I can tell you that 24p is 24p regardless of which camera you are using, unless you are using an FX1 in 24f mode. All of the cameras I have used capture the temporal information exactly the same way. Please take a gander at some of the examples on my website, if you see excessive strobbing please let me know.
