Flashing white random pixels in all BMCC footage

PostWed Dec 05, 2012 11:10 pm

Hi,

I found single white pixels popping up for 1 frame at random parts of the image in almost every BMCC footage I watched starting from John Brawleys stuff.

I don´t mean the stuck white pixels I opened another thread for some time ago.


You can see it here perfectly


Look from 1:45 min. (I think the whole review was shot with a BMCC)
White flashing single pixels every few seconds randomly. Watch fullscreen in 1080p on a big enough display.

In the review they say they have only one camera, but those white pixels match exactly with any other BMCC footage.

What is this???

Mr Frank Glencairn: Have you run into those problems with your BMCC? Maybe you could just shoot an evenly coloured wall in prores and raw for a few seconds.

I'm pretty sure that part is being filmed with another camera, not the BMCC.

You´re right. Just saw the reverse angle but nevertheless it is an anomaly i saw in BMCC footage, too.
If I could just find the Prores samples of John Brawleys Afterglow shot...I only find the RAW stuff but I specifically saw it in the prores files.

You can see the black spot issue though when he is going through the shutter angles :oops:
