GH2 Noise problem?

Recommended Posts

Hi guys,

I did some test shooting in lowlight and high ISO on my GH2, nothing scientific, just pushing the camera.

I noticed a strange dark pattern on the lower half of my footage on high ISO settings. Exactly the same darker line as this guy gets: https://vimeo.com/19563762

Sometimes it's visible, sometimes not, at ISO 2500 or lower it disappears. Is it a faulty sensor or normal behaviour in low light? I use the EOSHD Unified 88Mbit hack.

From what I gather this is a common issue with the GH2 in lowlight conditions where you are tending to be underexposured. I get it at any ISO but particulary higher ones. Sometimes its very obvious- other times you have to look really hard for it. Filming at 30p or 25p eliminates it completely. Just one of those things!

      i tend to get a lot of noise in my shadows, even with a very low ISO (100-800)
      I am shooting on a sony a6500 with the PRO LOG cine picture profile.

      Does anyone have any advice on this, is it like S-LOG where you have to expose +2 stops?
      Here is an example (Rendered at maximum depth and exported with vbr 2 pass 25/30)
      especially the first couple shots is noisey in the shadows the exposure shouldn't be less than -0,3 and this shows even before youtube compression.

      Hope you can help

      Greetings folks! Does anyone still happen to have EOSHD Unified Patch? The file is no longer accessible on Andrew Reid's website. I found the Vanilla Hack on here and hope to find the Unified Patch.

      Recently created a new (one-off) LUT for the Panasonic GH2 because like me, I know there are people out there who still use (or would love to get back into using) this soon to be forgotten gem of a camera for video. Though it's not free, it's still cheaper than a Golden Arches Meal and worth checking out the page even if it's just out of curiosity. Thank you.

      Just to be very clear... not shot by me!! I wish it was! It looks great. 
      But I just happened to come across it, and had to share it, as it is a nice example of what can be shot with GH2 in capable hands.
