Re: What does ISO have to do with HDR PQ or C-Log?

I normally shoot HDR PQ with my R5 and deliver HDR videos with Final Cut Pro on my Macbook M1 Pro. I have no problem with  editing and grading either HDR PQ or CLOG 3 in same video but:

I have a question regarding low light shooting.

HDR PQ have base iso of 400, and Clog 3 have base iso 800.

If I'm shooting in low light.. city lights or similar and end up using iso 12800.

Is there a difference in HDR PQ or CLOG 3 noise wise shooting at iso 12800 caused by the different base iso?

shooting at iso 12800

* HDR PQ is 5 stops over prefered iso 400

* Clog 3 is 4 stops over prefered iso 800

Anyone with knowledge?
