I'm also happy to share my emailaddress by PM to get some footage per mail. I'm interested in file size (although this has been discussed) and overall image quality comparing the color and bw model.
Hi Rainer, I've just sent you a few test clips, still too dark with max shutter, need to finish my flashlight monster battery mount

The filesize depends solely on bitrate, which you can set for each save. The final clip size depends again on which parts you've discarded/left in, for example, my clips average from 4 to 10mbit, but I think I always set higher values for the saving process, e.g. 15mbit. But that's just the maximum bitrate allowed, if the clips are too dark, like some of mine, they compress very nicely...

All the best
Martin
