Pentax K5 Video Issue

Hey everyone,

Recently I used my K5 to film some stuff around New York City and although almost unnoticeable on the display screen at the time, the video had some pretty noticeable lighting fluctuations when played back on the computer. It'd go from bright to dark over and over again, as if a cloud is constantly moving back and forth over the camera. Are there any ways to reduce that? I'd like to film something with consistent lighting throughout the video because it gets very disturbing.

Here's one of the videos:

Ignore the content of the video because it is crude and irrelevant. The largest lighting shift occurs early on. The fluctuations also happen in the day time as well.

Any suggestions?

Auto-exposure lock (AE-L). Press it.

I guess you also have center weight light metering selected, that means it will concentrate on getting the right exposure on a very small spot in teh middle of the screen and thus change exposure drastically depending on what you aim at.
