I have a video, shot with a recent but low-end camcorder (Samsung HMX-Q10) in Full HD 1920x1080/50i.
The problem is that there wasn't enough light (I guess) and the camcorder added some "parasites" to the video on the zones in the shadow (blacks are quite okay, but dark zones are not).
The kind of parasites that you may see on that video (on walls for instance) (this is not a video shot with that camcorder, nor my video).
So, I don't seem to be able to remove them when shooting, whatever the parameters of the cam are. I still need to try with more light, but I'd like to know if it is possible to correct that with a post-production effect on my existing video, especially with Sony Vegas Pro.
Moreover, is there a way to prevent the cam to add those artificial elements to the video ? This looks like some numeric elements added to the video, like the cam tries to correct the lighting. Can't the camcorder write exactly the image it gets from the lens, even if it's too dark ?
Can I achieve this kind of dark image with my cam (or maybe it is darkened in post production ?)
