Canon 70d grain even at low iso (100) using wide angle lens

Hi,
I am a canon 70d user. I have been using 70d for more than one year. Now i noticed a problem with my cam when shooting video. I was planning to do a musical video outdoor. I use 18-55, tokina 11-16 and 50 1.8 lenses.
There is pretty much noise or grains in the video when i use wide lenses even at iso100 Ap: 2.0 shutter:100. (i shoot in 720p 50f (Pal))
Picture Style: cinematic /standard/neutral (all have grains)
White balance : Auto
The video quality is very bad. Even i shoot in shades in woods or in bright sunlight i can see grains even in live view .video is very pathetic and gets wirse when edited

Please help me to solve this problem

Do you still [see] the noise when you take still photos?  Can you post a sample of the noise, either a still or a frame grab? 

 

You could always try resetting the camera, which is performed in two places in the menus.  Try changing the memory card, too.

Try ISO 160 instead. It is ISO 200 overexposed and digitally pulled back.

And at aperture 2 you will loose light because of the design of your sensor. Canon increases the ISO and you can't change it.

Can you post a sample of it?  You say this only happens with your wide angle lens?  I am beginning to suspect that there might be nothing wrong.  It is possible to zoom in close enough on almost any image and see some noise, especially with the lenses you listed.

Are you sure you're not just using variable ISO with 100 as the floor?
