Canon 70D grainy (Noise)
I have a canon 70d with a SIGMA 30MM 1.4 and a TAMRON 90MM. but there is a lot of grain and maybe bad quality in my video shots. I have seen other videos on youtube of this camera and the old 60D with the same lenses with much better quality. And i have tried the same settings as them, but it still comes out much more grainy then theirs. My settings: FPS 24. Shutterspeed 1/60. Aperture 2.8. ISO 800. Do you know what the problem could be.
And i also tried going for the same settings as this video was set at in a bit of low light, But my video shot came out so much worse and grainy than this one : https://www.youtube.com/watch?v=sTqFriZvQ-4
And my video location was much lighter, which does not make sense that it is more grainy than this.Thanks in advance!

All of the Canon camera forums are mapped together. We don’t have a ton of photography posts, so any post in one of those forums appears in all of them, in an attempt to provide the best chances for an answer. We do this with a number of lower-trafficked topics, such as shared storage.
So this one’s as good as many. 🙂
Anyone have any experience with this?

Try setting your shutter to 1/50 to emulate the 180 (actual 178) degree shutter of a film camera since you are shooting at 24fps.
Also, only shoot with ISO in multiples of 160: 160, 320, 640, 1250 (as there is no 1280). I get no noise at 640 on a 5D mark III. I know this is a different camera but it should be close to the same as far as noise. at 800 with no or very little light you will get noise in the shadows.

I second all the Warren says. Trying to get your shutter speed as close to 180 degrees (or double the frame rate) is best practice, though that won’t really impact your noise levels as much as your motion blur in the frame. If you’re looking for explanation about what this is see here. What Warren says about ISO is exactly right with Canon DSLR’s. Trying to stay on the multiples of 160 is best practice. See here for explanation.
I’d also add that the video you linked to looks like it went through some color grading (or they had a really hard time finding the right white balance! :-). So the blacks are very crushed in that video which would hide some of the noise. They may also have run a denoise filter on the clips as well, further reducing it. But keep in mind anytime you raise your ISO, making your sensor more sensitive to light, you’re going to increase your noise as well. Depending on the camera, the shot, and what you are demanding the increased noise may be ok….or it might not be acceptable. If it’s not acceptable then you need to bring more light into the scene so that you can lower your ISO setting.
Hope that helps a bit!
