Hello, I recently started shooting video with the Voigtlander 25mm on my Lumix GH2. At my last shoot I started to get these large rolling lines through the image. Here is a clip:

Anyone have an explanation for this? I've shot in this environment plenty of times with the kit lens and it's never happened.

Thanks in advance for your help.

Just that lens causes the interference?

That is not a flaws, it is the shutter speed not correct under the type of light that you have, change the shutter speed and it will go away.

I am in agreement with Khoi.

+ 1 Definitely shutter speed

It was fluorescent lighting I'm sure. Happened to me and I had no idea what what going on, it freaked me out. I eventually figured it out.

Anyway to minimize this issue in post?

I agree with the rest....flicker. I don't know any to fix it n post though.

No easy way to fix in post. I am curious about the conditions that could create this as it resembles the bane of analog video, radio interference in the wires. If this is the result of 60hz fluorescent, I assume a shutter speed of 1/20th would cause this as the chip scans down.

Thank you all for your help. I will definitely adjust the shutter next time!
