Even at ISO 200, my video is very grainy and pixelated, primarily in the darker spots, but I've seen nice videos with this camera, but when I set my shutter speed to 1/30th, quality to 1920x1080 30fps, aperture 3.5 and ISO 200, it still looks like crap! I'm getting really discouraged because I bought this camera for video and pictures, and I wanted to use it for a YouTube channel, but the footage is grainy and unusable!!! Please help, I hate dealing with all this. I bought it used on Amazon a couple months ago, but this is just crap video. Even in moderate light, the darker spots still look like crap!
If the exposure is not accurate, particularly if video/still images are under exposed, few DSLR cameras can make videos/images free of noise. Photographer/videographer knowledge and skill is still required to make acceptable video with any DSLR camera.
