Mystery green "bubble" dot in viewfinder (which is also recorded)- how to turn off please?
on Oct 27, 2014 at 1:14:13 am

Hey folks, I have a Panasonic HVX200 and I must have pressed something externally because all of a sudden I have a small green "bubble" dot at the bottom of the screen left of centre in the viewfinder and I cannot turn it off.

I believe that it is something around the area of inside the viewfinder covered area as didn't change any menu settings but do remember holding it cradled while the viewfinder was open and thinking that I hoped I hadn't set something.

This "bubble" dot could also be a very tiny "1" and looks like the 3D dots which were so popular with the first OSXs. It appears ON the recorded clips too. :(

Can someone help me work out how to get rid of this before I go completely mad please? Thank you!

Hi, thank you for your response. I couldn't see how to do that before. :O

Yes, I can post a screen-grab from where it first became apparent (note- I now see a faint grey vertical line running up and down through the green "bubble" dot which is not shown here):



It is in Brigid's hair, her right hand-side and bottom left of centre of the screen..

Looks like it might be a faulty pixel on the imaging chip(s). Check with support for your camera and see if there is a procedure for masking bad pixels.

Thanks Tom, I sort of realised that when I saw the grey line (which only appears in certain light conditions and on low movement- almost like a "shadow"). Unfortunate as I will need to get it repaired now. Drat, drat, drat!

I know how to deal with it on existing footage, thanks (duplicate clip, clip to equal numbers of pixels immediately adjacent and off set to cover) but really hoped that it was just a digital "light" of some sort. It just looks so weirdly 3D. :(

Again, check with Panasonic support. With many cameras there is an engineering/setup routine that may be able to mask or restore the bad pixel. It's a software/firmware fix and shouldn't cost anything (or very little). I just don't know whether its available on the HVX200, but a phone call should answer the question.

I actually did go to Panasonic support directly and have yet to hear back. In my experience users are generally better sources of information that "support" anyway as they actually have the best test experiences ever. But I solved its riddle for myself and will, as stated, need to get it repaired one day.

I have solved this- it is not a dead pixel (didn't think it was- it is lurid green and has a dark halo which makes it appear 3D).

It is the result of a £60,000 laser scanner's light hitting the CCD for the duration of one frame. :'( I even have the footage of it happening still and was reviewing the clip as it is in the video I am editing and thought to myself "hmm... Same colour... What if-" and WHAM there it was.

So that is why the 3D effect- it literally burnt and left the blackened edges.

Question is now- who in the UK still sells parts for the camera and/or is the CCD on the NTSC model the same as my PAL model... Oh boy- research time!
