Hi there, judging from the original video provided, the noise is in the normal range. When shooting DLog material, you can adopt the strategy of exposure to the right, which can capture the details of the dark parts well, while retaining the details of the bright parts, but it should be noted that once the exposure is underexposed, DLog is prone to a lot of noise; if in the optimization, you need to adjust the exposure value lower than the right exposure, which means that you need to use the price of increased noise in the dark part to exchange the details of the bright part. Shooting with DLog can expand the dynamic range and color gamut of video recording. After the shooting is completed, after the color correction, the human eye's look and feel are restored. During the color correction, the most interesting brightness interval can be selected for preservation. It should be noted that the DLog mode will compress video files, resulting in a loss of image quality. Therefore, under a high dynamic range, it is wise to use DLog at the expense of image quality. If the dynamic range is not high, do not choose DLog mode. DLOG and HLG tend to prioritize post-processing space and dynamic range modes, and it is recommended to use low ISO sensitivity shooting when the light is good.
Usually, post-processing software (such as the Temporal NR function in Davinci Resolve Studio) can effectively eliminate the noise in DLog-M and HLG videos.
Both our senior in house editor and the colorist both know what they are doing,, thx.
I don't feel these images are underexposed since the noise appears on the entire left and right side is darker as well as lighter parts. But could be informative for new buyers: expect noise in your images.
