Noise

It would be a lot easier to get an answer if you told us all of your settings...mode used in ....lens...etc.
 
My bad Ian. I was in M mode, shutter at 30, ISO 1000 and using 14-140 kit lens. I don`t have much experience shooting video with this camera. Been using the HMC150, but i know the GH2 can shoot cleaner in low light than the HMC150. I`ve seen it.

Instead of using my HMC150 last night i took my GH2 out for work. When i got back and edited my video i notice alot of noise. Anybody have any suggestions on why so much noise?

Personally I'm going 'what noise'... for the conditions, the youtu.be video looked pretty clean. What I did notice was that the flashing lights of the emergency vehicles did 'add' a bit of flicker to things, but I did not see
'noise' like 'intensity jitter in pixels' in the dark areas, as I've seen on really noise low light, nor did I see any banding associated with low light and high ISO, that I've seen on my own GH-1.

If you mean "M mode" as in the M that sits along with S, A and P on the control dial, that might be your problem. You need to turn the dial to the setting that has the movie camera icon with an M behind it. That will let you into Creative Movie Mode where the highest bitrate settings are.

Note also that if you set your shutter speed to be lower than your frame rate, you will force the camera to produce low bitrates.

Low bitrates = noise.

Thanks i appreciate the feedback and help. So should i not use IR and ID in low light? and is the shutter speed not lower than the frame rate a general rule for any camera?
 
Nope, they negatively effect the image as the algorithms they use are more primitive versions of what you can easily do in post with more powerful hardware. IR I personally wouldnt use in video as some people complain that it's too sharp even with sharpness dialed down. ID I'd leave off too, as unlike the canon/nikon dynamic range extender, it prioritises and boosts the shadows (thus boosting noise) so the user has to apply some negative exposure to keep the highlights safe, whereas Canon/nikon slightly underexpose the scene and then use a different tone curve to bring back the mids and shadows.

I've learnt that there arent really any "rules" per se, rather, generalisations, typically, you use the 180 degree shutter (25fps,1/50) however, you can use different shutter speeds for different effects. One cool thing on the gh2 is it normally wont let you go lower than 1/25th i think, but if you switch the focus dial to MF, you can pick any shutter speed the camera can do.

If you just press record on the camera in any mode other than the movie camera icon mode, it will record in 50i/60i depending on your location, put it into movie mode for progressive options. Lastly, the kit zoom is quite slow, a lens like the 20mm pancake with etc might be long enough for the shots you wanted, and being around 3 stops faster, would easily let you use lower isos
 
I really appreciate all the help. I`ll do some more playing around now that i have feedback from you guys. I`ll see what i can come with later tonight. Thanks once again.
