Canon 6D - Shutter Speed 1/100 or 1/125 Problem?
on Feb 10, 2015 at 1:26:33 am

Hi, I don't know how common this problem is, but when I raise the shutter speed to 1/100 or above, I start to get jagged edges on straight lines and sometimes random colours showing up. Now I already know I shouldn't have to go that high when shooting at 24 or 25fps, but this seems kinda worrying when I've had something similar when shooting at 60fps when I'm supposed to shoot at 1/125. Or what if I simply want to increase the shutter for artistic effect?

Do I have a setting wrong, is the 6D known for this, or is there anything I can do to fix it in post? Or am I entirely wrong about it being the shutter speed causing this?

If I'm not being clear, you can find examples of what I mean in this video:

P.S. I'm aware this is a rather rookie question haha.

Are you talking about the wires? If so, two thoughts come to mind:
I'm not familiar with the 6D, but shoot a lot with the T2i (550D) and the T5i (700D). To my knowledge the internal resizing from that 18MP sensor (20MP with the 6D, isn't it?) is not really the best you can imagine. From what I read, it's not really a downsampling, but simply a skipping lines (I can be wrong here), that leads to jagged edges. So I presume(!), that if you shoot higher shutterspeeds, this becomes more apparent, because you have less motion-blur - if that makes any sense. Random colours can be a side-effect of that as well, or it simply is colour noise, introduced by higher ISO needed with faster shutterspeeds.
All just assumptions
