    Hey guys,


    I'm normally a DP/2nd Unit director but have picked up some covid side work helping a friend with an edit (as much as I feel like editing is pulling my teeth out I think it helps my shooting/directing).

    I wasn't on the shoot and I know the operator was new to the camera. There is odd noise in certain Luma and chroma value areas but it doesn't really appear to be very predictable between shots and lighting schemes. One shot is ok and then next is horrible. I've been using Neat Noise with good results on a few of the clips that have a clean area to pull a good sample from. Unfortunately, many of the shots don't have a good area to sample, normally I'd just pull a sample from the clip after or before but the randomness of the affected clips won't let me do that.

    The operator feels horrible and lives in town and would love to help out in any way. I had an idea to put the bad clips back onto the camera and use the same settings from each bad shot to shoot the Neat Noise target (https://www.neatvideo.com/support/ho...bration-target).

    I'd just use the metadata if it was my Red but the Sony menu options are so deep that I think there is something weird and more obscure than I'd probably notice.

    Anyway, has anyone put clips back on a Sony FX9 or similar?
    Has anyone shot Neat Noise targets after the fact?

    Thanks!

    You can check the original settings for each clip with catalyst browse. You can then use those same settings for shooting the noise profile target. Hope you find this info useful.

    Thanks Luis! I've been trying the Catalyst program. Everything seems in order there but I'm not a Sony expert to say the least. I have some screen shots of the noise issues and of the metadata if anyone would care to take a look if there is a blaring setting issue that I'm not noticing. I'm sure the operator would greatly appreciate it as well.

    Video of example (with the H264 export it all kinda looks bad if you look at the full res screenshots below the rocks are noticeably horrible) :

    I don't know anything about the camera, but just happened to have read this story yesterday:

    Thanks Brian, sounds like the noise issue discussed on CineD was the issue was from the more recent 2.0 firmware and the footage was from back in February on the original. Thanks!
