I have recently asked about Auto ISO for video, and got great responses. I would like to have further clarifications in these regards.
I am planning to film an event in a public place. The scene will be fairly dynamic, and I won't have much of a control over what will be going on. I believe I won't have much time for settings either.
For these reasons, I was planning to use AWB and Auto ISO. Specifically, I was thinking about setting the ND filter and aperture such that the correct exposure would correspond to ISO 200. That way, the camera should be able to go up and down when needed.
Now, considering that each clip will be no more than 4 seconds, will I run into any issues with the above strategy?
PS: I will be using a 5DMIII (no Magic Lantern).
