Troubleshooting gamma issue from Panasonic S1 night videos

[Stuart Richardson]

Hello all. I hope that you might be able to help me. I am a professional photographer but a video neophyte. I am working on a series of videos taken at night for an art piece, and I am being stymied by a mismatch from how the footage looks in camera, versus the resultant footage as viewed in VLC and DaVinci Resolve. Videos that look like they have decent shadow detail in camera come out with blocked shadows and significantly darker on the computer. I am not sure what I am doing wrong here...I run a custom printing studio and use a calibrated Eizo CG-3184k monitor, and my workflow worked fine with the Sony A7S...something with the S1 is not working the same for me. Right now I am using the Camera Natural picture setting and the 4K 10bit 422 150m 25p MOV mode. In the past, I was using the MP4 mode. Luminance level says 0-1023. If anyone has any suggestions, I would be happy to hear them.

Thank you!
