best 24 p settings?

Hey I am somewhat new to the dvx100b and have been learning new stuff everyday. I have done numerous test shots at 24p, 24p advanced, interlaced 60i, and a bunch of other stuff. Now my question is why is it that I find filming at 60i to be much more clearer and sharper, while filming at 24p tends to look a little grainy? I have set my shutter to 1/48 (double frame rate), set dial to F6, white balance, set the gain to low, and the whole nine yards but the picture is still somewhat grainy and laggy in some instances. For example I shot some indoor stuff which was in low light and filmed in both 24p advanced ad 60i. I then watched the footage on my television and saw that 60i looked much better. Now I'm guessing I must have something not set right? In detail can I have some of your settings you use?
 
Standard shutter for 60i is 1/60; standard shutter for 24p is 1/48. In 60i with 1/60, the shutter is always open and letting in light all the time. In 24p with 1/48, the shutter is only "open" half the time. So, 60i at 1/60 lets in twice as much light.

You can equal the light in 24p by setting the shutter to 1/24, but you'd be giving up a lot of the filmic motion by doing so.
 
If 60i looks much better, as it should, then use it. Video is all about things looking good. i suspect the reason in this case is that you're using the camera without the tripod. The constant motion causes far more blur and/or judder at 24fps.
 
Thanks

Yeah that's what I noticed when filming moving objects. It would be somewhat blurred and jittery, but on a tripod it works out very nice. I guess it really depends on what you're filming; however, I'm still curious about the settings other people use. If anyone could give me good settings that worked out good for them in low lighting and indoors using 24p I would greatly appreciate it. Thanks again.
 
filmic motion is always present in 24p it just may have tons of motion blur. Mann shot some of Collateral at 1/40 shutter and the low shutter blur looks gritty and makes everthing look as if it is moving faster than it actually is. 1/24 can be pulled off with a tripod hardly any motion goin on in the shot. too much motion and u got some generic flashback from law and order.

The best thing to do is to add more light.

Part of cinematic motion is the stutter, though. A slower shutter can give a desired effect -- it's all subjective -- but one of the reasons the DVX looks so film-like is because it shoots more like a film camera than other video cameras do. Part of that is the shutter speed. Slowing the shutter makes a move back toward how a video camera works.
 
that's a great point. also you need to open ur iris up. you said you had it a 6, that's really closed for indoors, it expose my dvx so that the iris is always a t around 1.6.
