R5C with 16mm f2.8 Lens - Video looks constantly dark.

[SCSR_Studios]

I have an R5C and I'm shooting with a 16mm f2.8 lens. I have auto iris and auto ISO turned on and everything looks super dark. Even with studio lights, I feel like the camera is several stops down from where it should be. I've talked to canon support multiple times and we just cannot figure out why the video looks awful. I have to color grade everything substantially in Davinci Resolve. I followed both tech support and a youtube video about setting up auto exposure on videos and I feel like the settings are all correct. Anyone have any ideas?

What were the settings used for the scene (aperture, shutter, ISO)? If you take a photo, is that also underexposed? If you put the camera in full auto, do the photos also end up underexposed?

Any details you can provide on the continuous lights you used would also be helpful.

Greetings, 

Adding to Ricky's questions... Can you test with another lens?  What video mode are you shooting in?  Are you shooting in RAW / CLOG?

Might you have set low or high aperture/ ISO values?  

Please provide as much information as possible as it will help us understand your issue better.

Photos are absolutely perfect. I used Auto ISO and Auto Iris on all videos.

I can test with another lens yes, I will get that done, but photos look amazing. I am not shooting in Raw or CLOG. I don't really know how to shoot in CLOG just for the fact that I don't know how to setup Resolve color grading for CLOG.

Greetings,

Please also verify your kevin, white balance setting.

For the photo, what were the exact settings? If you then set to manual with those same settings, the video should be good. Of course account for the desired shutter speed by adjusting aperture and ISO to an equivalent exposure.

[SCSR_Studios]

You can't do that with the Cinema OS, the modes are completely different.

Auto white balance.

Surely you're able to see what the settings are though. For the photo with proper exposure, what are the exact settings being used? When taking video footage, what are the exact settings used there?
