In terms of RAW, the XF605 doesn't capture that. See page 53 in the User Manual for details on the two different formats that can be recorded (XF-AVC and MP4).

I would like to know if there's a way to reduce video grain in lowlight with a bumped ISO or Gain. Is there in-camera setting for the XF605 for this?

Your camera records in XF-AVC and MP4. It does not support Cinema RAW or Cinema RAW LT. Let me do a few minutes or research for the other questions.

Canon introduced CLOG3 (what your camera has) which offers similar performance to CLOG2 in a codec that is not as processor intensive. When you shoot in CLOG3 the contrast and saturation of your video is reduced. This helps with file size. You then have to apply a LUT or color grade in post.

Anyhow, for both cinema cameras and camcorders, the maximum possible dynamic range can only be achieved when using an ISO/gain value that isn't at the minimum. For the EOS C70, base ISO is 800. You can certainly use lower ISO/gain values (for less grain/noise), but at the cost of lower dynamic range. For scenes though with low dynamic range to being with, this isn't a problem.

Manual ISO Speed Gain value. Think of this like a gamma curve. How smoothly black transitions to white. Your options are (L, M, H). You'll probably want to stick with low or medium in most cases.

Which Video Style do you recommend I use that has the best possible Dynamic Range (for blacks or shadows, and lights or highlights), that also allows me to use the lowest possible ISO or GAIN to reduce any or all grain in my footage?

Shooting in LongGOP vs IntraFrame. Basically this. LongGop captures only the difference between the captured frames. Less processor intensive, smaller files. IntraFrame (All-I) captures every frame individually. Larger files and more processor intensive. This is a representation of how each affects file size. The higher bit rates and resolution are capturing more detail. This is at the expense of file size. Becoming familiar with proxy recording can help with this.

In LOG3 mode, set to Gain, it starts at 0 dB, is that the same as 500 ISO or lower, thus does that mean little to no grain at all, is using Gain better in another sense?

Do you have a copy of your user manual? You should spend time reviewing it as it will help you understand and control your camera better.

It appears that the minimum ISO of the XF605 is ISO 200 (gain of -6.0 dB). A gain of 0 dB should be ISO 400. See page 61 in the User Manual for details.

The advent of the microscope in the operating room revolutionized neurosurgery. We traced the origin and evolution of this important invention from the first magnifying lens to its practical application in neurosurgery. The concept of magnification evolved from unexplained observations in ancient times to the invention of the microscope by the late 16th century. In the subsequent 3 centuries, scientists made technical advances that greatly improved the power and utility of the microscope. By the early 20th century, otolaryngologists became the first surgeons to use the microscope in clinical surgery. After World War II, ophthalmologists and vascular and plastic surgeons began using the microscope in the operating room, making further technical improvements. It was a relatively small group of pioneering neurosurgeons in the late 1950s and 1960s who transformed microneurosurgery from a revolutionary and unorthodox "experiment" into the standard of care in much of modern neurosurgery.

At this point, I think I would spend time with the manual and the camera side by side. Your camera also has built in ND filters which allows you to control exposure with finer granularity with wide open aperture when a shallow depth of field is desired. The 605 is a very nice camera. I'm sure you will enjoy it.

Your camera also has 3 built in BT.709 Picture Styles (Normal, Wide, Standard) which can be used during filming to further reduce the amount of post processing required for a finished product.

Hi thank you for responding. I still have an issue with grain or noise in the video even during daylight using low gain at 0.0 dB with Main Rec Format at MP4(HEVC) YCC420 10 bit, Main Resolution 3840x2160, 23.98 Frames Per Second, Gamma/Color Space BT.709 Wide DR / BT.709 video profile. I think the video profile is what matters, but I am not sure. I want to know anyone who has knowledge using this camera, which video settings for outdoor daylight shoot gives you the optimal image quality/resolution, best Dynamic Range, color, and sharpness and noise/grain free video.

Camera gainvs exposure

ISO is interchangeable with gain. Camcorders typically use gain values for sensitivity whereas photo cameras and cinema cameras use ISO. A full stop of ISO is doubling or halving a certain value. Whereas for gain, a full stop is a difference of 6 dB (which I really dislike since for other things, 3 dB means a doubling of power).

Earlier you asked why your ISO was set to 500 in CLOG3. The minimum or maximum ISO value can be set based on shooting conditions. The camera defaults to a estimated "safe" value which could work in many shooting scenarios but might not be ideal in every shooting situation. The camera's processor has some influence here as far as the level of detail it is able to capture "cleanly". Again, it has limitations and requires your input or decision based on the shooting scenario.
