This past week, Canon released new firmware for the Canon EOS R5 C that improved image quality in C-log 3 when shooting AVC or MP4.
It turns out this update has allowed the Canon EOS R5 C to be approved for Netflix productions when shooting in XF-AVC (4K).
Why Netflix has an approved camera list
To help creatives produce their best work and create compelling visual experiences for our audience, Netflix requires 90% of a program’s final total runtime to be captured on approved cameras using the following capture requirements. For nonfiction content, this threshold may be more flexible.
We collaborate extensively with the creative community, camera manufacturers, and globally recognized experts to approve cameras that support reliable and flexible production workflows. Approved cameras have been evaluated by Netflix technologists to ensure they meet image capture benchmarks for dynamic range, color accuracy, detail rendition, signal to noise ratio, resolution, and key workflow requirements. These evaluations help our partners know they’re using the best and most appropriate capture technology when telling their stories.

I have doubts whether the firmware upgrade has anything to do with Netflix approval. Netflix test procedures take time and the new firmware is not even 48 hours old!
But whatever it is, that R5 C is now Netflix approved makes me happy.
Oh wait, where are those who \"It doesn\'t shoot in Clog2, it\'s a trash camera\"?
Autofocus is rarely used on features. The R5c autofocus is great compared to the majority of cinema cameras.
Regardless cinema cameras usually don't have AF, likely not a criteria for Netflix
Even though the sensor cannot fully utilize the full log2 curve, it would still offer something better than log3. No reason why the user cannot decide for themselves if they want to use Log2 or Log3.
I really, really dislike that I have to use Clog3 on my R5 and it comes out in H265 when I can grab my Sony and record Slog3 in H264...
You can verify yourself using RAW and switching between CLOG2 and CLOG3.
This seems, to me, that it is a workaround with the issue that Canon worked together with Netflix to achieve. Something that meant they didn't need to build a new camera from the ground, neither Netflix needed to keep rejecting an existing camera for use. It's sort of a win-win situation for them. And I do think that Netflix and Canon have been working on this together in the same manner that Netflix worked with Sony for the certification of the FX3 - something that took around 6 to 7 months.
Biggest thing looks like a faster turnaround time between stills and video mode and a energy saving feature.
Battery Saving mode is specifically related to 4K 60 XF-AVC footage and should use 30% less power.

Because Canon does not want users to shoot bad footage with the Canon cameras. Simple as that. Sony having SLOG3 in all cameras is a marketing gimmick. It's not a technically desirable feature.
CLOG2 requires the sensor to be capable of 15 stops of dynamic range. 16+ for extended CLOG2 on the DGO sensors.
The R5 only has 13 stops of dynamic range. Canon squeezed another stop of dynamic range out of that sensor with CineOS in the R5 C. And that is why it only get CLOG3 and never will get CLOG2.
If you were to record with CLOG2 on the R5 C, all you'll get is more noise in the shadows. Nothing more. Tests using RAW footage interpreted as CLOG2 have exactly shown that. You just add garbage, if the sensor can't handle it.

Both the a7iv and R5 measured a similar 14.7/14.6 EV sensor.
According to cined, the R5 with clog3 shows 10 stops, the a7iv and a1 with slog2 are at 13.
Now maybe it’s not the log curve, or maybe it’s because canon forces us to record in h265 and information is lost in the high compression, but all I am saying is, Sony gave me an option to use a log curve developed for high grade sensors, and it made “some” difference.
Even if clog2 cannot be fully utilized, maybe we can get 1 more stop if dynamic range? Maybe for pro’s it will make streamlining footage from a cinema camera and the R5/R5c a little easier since they’re shot in the same log?
My point is, why not give us the options to use what we want to use. I would love h264 compression so I can actually edit the footage and not have to convert it in post.
Maybe the option of 4k120 ipb, etc
