I just bought this and the picture seems to change focus every few seconds. If you watch the grass
it is more noticeable. Any Ideas?

Due to the way video compression works, details in the image shift slightly at a regular interval; the rate depends on the "I-frame" interval of the H.264 stream. That's what I see in the video here. If you go into video configuration setup and change the I-frame interval I think you'll see that change. If you want the best possible image you have to set the highest bitrate; good resolution on all those grass blades takes a lot of bits.

I will give that a try. The U Tube video actually looks better than the live stream.

I lowered the resolution to 2304 x 1296, changed the FPS - 12 , I-frame - 24 ,bitrate - 8192 seems to be better. I will play a little more.
Thanks, cam235 for the suggestions.
