Samsung NX300 produces strange flicker in video recordings?
1

Hello there,

I'm new here and also new to the Samsung line of cameras. And already I have a question

(And beforehand: please excuse my English, it's not my native language)

My girlfriend bought the NX300 a few days ago, and we have started to make some test photos and videos with it. Everything seems fine with the photos, but as we were reviewing the videos on a computer, we found that there is some sort of "flicker" in all the recordings. I'm not so very experienced in digital filmmaking, so it may well be that I'm doing something wrong here - or has anyone had the same issue?

Here's some info on what we did.

- Setting: HQ Video, PAL, 1080p50

- Lens: 18-55

- Firmware: 1.32 (I'm aware there's newer firmware available, but due to the problem described above we're not yet sure to keep the camera, so I'm hesitating updating it yet)

- Tried in AF as well as in MF

When recording static scenes, there's a flicker effect. For example, if there is grass on the ground, it's "pulsating" ca. every 1 second becoming blurry and then sharp again. The same happens with stuff in the background. It looks more like a "pixelization" problem, not so much like the AF working. 
Has someone noticed that before?
Could this be related to the Samsung H264 codec? Or the SDHC card being too slow (it's class 4 only)? Or has that something to do with not handling settings right, like EV / shutter speed? 
In another thread on this forum I found info that the bitrate is higher when recording in NTSC, so we'll gonna try this tomorrow on a SD card class 6 (better SD cards are coming, but right now it's the fastet we got).
Any help or tips are appreciated - thanks in advance!
And sorry for the long post. 
tl;dr: Video on Samsung NX300 flickers, need help.
