HD200 Grain Problem
 
I've been using the 200 for a while and I still get grainy footage. This especially happens when I'm shooting wider open. I don't have the Gain turned up so whats goin on?

The Full Auto switch isn't turned on accidentally is it?

Juan Pablo Ramirez September 17th, 2009 07:01 PM

No it isn't. I don't understand why the grain shows up.

If you're shooting at 720P60, the GOP is 15 frames and there CAN be significant MPEG "mosquito noise", especially compared to the 1xx series, or so I've read on here. My experience in 60P is fairly clean but I don't do any slow motion or anything which would show off noise more.

Can you post a frame grab?

I while ago I rented a 250 to try and match my 100 for a shoot. Looking at them side by side on the same 50 inch Plasma I thought the 250 looked a lot noisier than my 100. This is through component using the Paulo v3 settings for both cams (v3 for hd100 and v3 for hd250)
I think we were shooting 30p HDV if that info helps.

Kind of surprised me...

The 200 series
 
are noisier, just a sad fact, the only reason I bought the 251 was the HDSDI out so I could bypass the hdv codec and eliminate a large portion of the noise. Still a good picture though, most non video people won't even notice it!

hi juan,

do you mean with 'grainy' the noise in the grey and dark areas? or do you see grainy details as well in the white parts?
