GH3 Getting Odd flickering on footage shot in daylight

It's the light from the building interior. The flickering light is 'orange', from the inside. All the exterior 'blue' light is flicker free. To avoid this you need to shoot a 50th ( here in PAL land) or i believe a 60th shutter (else where) depending on the country you are shooting in.

I experienced the same thing here, but I shot at 1/60. Wonder what the shutter solution here is in the states?

What about 25th/sec?

What types of lights did they have back there lighting it? Some Flo tubes and LED lights (not intended for video work) flicker when dimmed on camera but can't be seen by the eye. The new LED lights in a lot of household lighting sucks for this when dimmed.

For docs/factual sometimes you don't have control of all the lighting (well often). Would 25th/sec also work as it would get 2 full cycles? Should this of shown up in the viewfinder?

UPDATE: Now this is very weird. Did some experiments and in the viewfinder 50 looks good but 25 does not. I find this a little strange but the really bizarre thing is 100 also looks good!

The worst part is that not only do you sometimes not have control over the lighting, but also the SS is fixed! I was shooting that dance at 30FPS b/c I needed extended zoom. That meant, I really needed to keep SS around 60 fps. I obviously couldn't control the light. I have pretty limited options at that point!
 
Which is why when shooting theatre performance, if the client is serious about getting a decent video, you need to do a specific shoot where you have some control over lighting levels. Sad thing is that even if you explain that they still complain when it does not come out as they want it. We recently shot a performance with very low lighting and surprise, surprise it came out very dark and of course it was our fault;(.

As a side note were they using a projector to backlit the sheet, that would cause flicker. Did it show up in the viewfinder.
