Gen 5 uses a fixed log curve for all cameras that doesn't change per ISO so contrast is always consistent (it varies per ISO and camera on Gen 4), and also keeps the full range within video levels so highlight recovery in the right conditions is visible if checked, where on Gen 4 at native ISO or higher you generally need to pull the range down to see the recovered highlights. It makes grading from log more consistent and predictable and also for copying grades across cameras and even shots on the same camera at different ISO's. It also helps people using/making LUTs as the starting point is the same. Some people make LUTs and very precisely craft their gamma based on a certain ISO (usually "native") with Gen 4, but then someone may use a very different ISO that requires tweaking just to restore the contrast as intended by the LUT (I've seen people not realise this has affected their perception on liking some LUTs). Gen 5 doesn't have that issue.
So Gen 5 should become native on other Blackmagic Cameras like the Pocket 4K, Pocket 6K, UMPG2, and possibly the UMPG1 via a future firmware update?
This all sounds really awesome and amazing. Sounds like a great jumping off point for grading that will result in more consistent results.
Sadly just shot B-Cam with the G2 on a music video yesterday, but the director asked me to shoot ProRes because he had the Alexa Mini A-Cam shooting ProRes as well. Granted he is editing in Premiere Pro, and didn’t want to work in RAW. Still sounds like with the recent updates in the Beta that matching that ARRI would have been easier had he allowed me to shoot BRAW and processed it in Resolve.
