EOS M3 Noise

[Idkwhat2putheresowhatever]

Hey everyone, a few days ago I bought a Canon Eos M3.  Photos look fine but video looks grainy and glitchy on my Dell Monitor. I have attached a screenshot from the video and the photo. For the Sky, video was taken at 1080p, 25fps, ISO 800, F5.6. Photo was taken with the same ISO ,aperture but with 1/20s shutter speed.

Taken as photo

Here's another Photo: ISO 800, F5.6, 1/8. Video: ISO 800, F5.6, 1080p 25p

what is the shutter speed you use for the video?  25p is just framerate, do you use 1/25 or 1/50 or 1/something for shutter speed? and do not equalize ISO for photo like ISO for video with some cameras.  for photo the EOS m3 is capturing 24megapixels anmd for video it is taking the sensor resolution and scaling down to 1080p resolution.

The m3 is doing full pixel readout for videos?

I don't know if the low light video capabilities on the M3 is any better. To get the most out of the video quality, I'd lower the ISO to the native 100. If you need more light, use a lower shutter speed, on 25p, I'd personally use 1/50, and open your aperture to the widest possible. If f5.6 is as low as you can go with your lens, consider buying a prime lens f2.8 or even f1.4. Also, shooting in good lighting conditions is the best way to improve content quality.

I don't think there is something wrong with the camera, but in most cases, at any camera, you'd get less noise on stills, compared to video.

The shutter speed in the video is the same as the photos. Don't know much about cameras btw, just my first venture into the world of photography.

I can't seem to bring the ISO below 200 though. And I just realized I can use f3.5 but still a bit grainy.  I commonly film in places where there isn't as good lighting as maybe outdoors or studio lighting. Maybe it's time for me to up my photography skills lol.

That is weird, I haven't got the camera myself, but looking up the specs, it seems like it would be possible to set the ISO to 100. I also recommend using shutter speed 1/50, nothing less, and if you shoot in low light, you don't want to go any higher neither.

There is also an option where you can use your editing software to do noise reduction. Be careful, when you use the effect, you might blow out details if you push it too far.

Thanks, will try that later on. But I'm just wondering what exactly caused that graininess. It's sorta bugging me now ? If someone could suggest the cause of it please do so. Thanks. FYI, it's still grainy even outdoors where there's a decent amount of light

Noise is apparent on every digital camera, especially when shooting in low light. It is the sensor which receives electrical noise from other sources than the photons. 

When we use a higher ISO, we are amplifying the signal we receive from the light photons. Unfortunately, as we amplify the signal, we also amplify the background electrical noise that is present in any electrical system.

In low light, there is not enough light for a proper exposure and the longer we allow the image sensor to collect the weak signal, the more background electrical noise it also collects. In this case, the background electrical noise may be higher than the signal.

The M3 has a small image sensor, which often is more sensitive to noise than other formats.

Each photosite itself generates electrical noise that can contaminate its neighbor. In a larger image sensor, the photosites can be physically further apart and thus be less affected by that contamination.

A larger image sensor also means that the photosite can be larger, thus have a larger light gathering capacity. It is therefore able to generate a larger signal to noise ratio.

video camera in low light usually records video that looks very noisy and is especally worse with the code/compression in your camera

[Mihle]

Video is lower resolution than pictures, so I think noise will be more apparent on the video.

 

I don't. Know if that's the reason tho.
