Some overall questions

[mobiledeli]

I've had the dvx100a for about... a year or so now, and im very pleased with it. the only thing that im very annoyed about (and maybe its just ignorance) is that somtimes something blue, will have so much grain i cant even bear to look at it! also, like if i want to film something in a room, i have the blue from the sun pour in, is ther a way to like,.... i dont really know what im asking there. and last ting, is that somtiems the image is just so dark in a house or hallway, is that just the lighting?

If I understand you, you want to color balance that sunlight to match your interior lighting so that the sunlight never looks blue. The easiest way to do this will be with gels. You need to get some gels called CTOs (Color Temperature Orange) and tape them up over your windows or whatever, so that the blue sunlight is filtered to come out matching your interior lighting.

As far as in a house or hallway...That very well could be a lighting problem, also check iris and ped.

shutterspeed will play a factor. You might of known this already but a higher shutter speed in a darker place will ultimately make your footage extremely grainy.

inside depending on what your shooting and your lighting conditions, shoot at 1/24 or 1/60.

Some interesting suggestions here.
Here is my 2 cents, take it for what it is worth.

First, not shooting the color blue is not an option, you can indeed get nice looking blues with the dvx, but you have to make some adjustments. I use daylight as a nice background fill when shooting with tungsten lights, all the time. You do need to be aware of your exposure, and if your blues get too noisy, turn down the saturation, I usually keep it around -2 or -3 for most things.
As far as shooting indoors, well, it will be dark if your room is dark. Just like shooting with any camera, if there isn't sufficient light, you need to add it, or it will just be dark and grainy.

If your shooting 24p, I don't reccomend using a 1/24 shutter speed, unless you want the "blurry" look. Add more light so that you can keep your shutter speed constant.
