Re: [Motion-user] Grainy video only with motion

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

The 2560x1920 dimensions are for the high-res stream. I commented them 
out when I switched to the low-res stream so I could remember the values 
when I figure out where they should go. The 800x600 resolution is the 
actual dimensions of the low-res stream coming from the camera.  Could 
MotionPlus possibly be still using the commented ones?  I would think 
that, even if that were the case, the later values would take 
precedence.  I can try removing them altogether.
