late afternoon indirect natural light, indoors. grain and noise was constant and pleasing. Color was great and faithful...

But: In the middle of the shoot (two and a half mins in) after a pink shirt appeared on 1/5th of the frame, the image turned greenish, specially on the skin tones Mids.

this samples are two frames apart. direct screenshots from quicktime with avc plugin for playback of mts file.

I've also noticed this almost a year ago in a shoot, using original firmware. In a scene where yellow was background and blue and pink elements appeared in the foreground while panning. kind of like the pink shirt that comes in and out of the frame.

In this case it never goes back to normal up to the end of the clip, up to 5 minutes, the shirt keeps coming on and off frame every 10 seconds.

Anyone noticed this? It looks like although everything is locked the codec is performing some kind of auto white balance adjustment?!

I'm aware of the possible color shift in the first few seconds after you start recording, but this is different.

I've posted this on another thread but it was out of place.

I appreciate your input.

thanks
