The 2.5x video is taken on a cool dry night(although it did rain a little later that morning). The 5x video was taken on a night directly after a 4 hour rain. It was the kind of night everyone knows where its 90 degrees and it feels about like 110 degrees. Just wanted to post so people can see the difference in the images produced. Also, between the times that these two videos were captured there was a firmware upgrade which fixed an issue with aspect ratio. So, there is a slight difference in size(PAL vs NTSC). Even so, I think the point still gets across.
