That is correct, although they don't pump out reviews that often. Their reviews are often followed by ads or product showcases. 

Thank you for the heads-up, Jarred has updated the forum's software but it's fixed in the meantime from your notice much appreciated :- )

Well, at least Jordan Drake from DPReview didn't grade these, the shots look exquisite!

In my experience, there are two kinds of (serious) codec tests that people do.
The first is for when you have controlled shoots and you are trying to understand the absolute sweet spot of the camera.  For this, you shoot a controlled scene using a model (or two), test charts, and anything else you might think is usable, and you shoot it at 0, and then under and over by 1 stop, 2 stops, 3 stops, 4 stops.  Then you bring everything back to proper exposure in post and look at the skin tones and noise and other image attributes.
This is used in seriousness by professional cinematographers who do the tests and then work out that perhaps the sweet spot is +0.5 stops, and they'll shoot the camera there for every shot on 8 and 9-figure productions because that's the best place for skin tones, or whatever.  "You expose camera X at X stops under/over" is common knowledge once a camera comes out and is tested and everyone will do that - why wouldn't you?
The second is for when you're not shooting in controlled shoots and you want to know how far you can push the camera.  For this, you shoot a range of situations and deliberately push the camera in all sorts of ways, under and over exposing in a range of circumstances, doing things like in low-light under exposing with native ISO and raising in post vs rising ISO in-camera etc, filming in mixed lighting and fixing in post, filming in radically contrasty lighting, filming highly saturated things like neon signs and car tail-lights to see how it handles extreme saturation, etc.  These tests are designed to work out how far you can push the camera.
Taking one shot is suitable for neither scenario and tells you very little.  It's.....lazy.
I'd suggest that the people who use 5D with ML are actually out shooting rather than talking about cameras.  It's one of the closest matches there is for an Alexa (the others being OG BMPCC / BMMCC, and maybe Sigma FP, etc) so once you get that setup it's camera choice = solved so move onto next choices like lenses and lighting and composition and story and then navigating the entire process to make and publish something.
Here's a test I did with the GH5 10-bit 150Mbps mode, which isn't even the GH5s best mode BTW, in trying to break the codec.  


I chose a flat looking scene and tried to break the flattest looking part of it (the clouds) to see what was there.  This is informal but is an example of a test to see where the limits of the 10-bit are.
I'm not in the R3 target market (or Canon Cripple Hammer target market for that matter) but if I was spending $6K on a camera then I'd want to know:
where the sweet spot of the camera is how far I can push the darn thing and still get a "nice" image (ie, acceptable for a main shot - according to my standards) how far I can push it and get a shot that is still usable in an edit (ie, for 1 second) ..and you want to see some work that puts things in context?  Sure.  I am an amateur who shoots travel and events for family and friends in available lighting (which is absolutely awful lighting BTW).
Here's a couple of videos where the camera was pushed beyond its/my capabilities.
and 
and lest you think I don't know WTF I'm doing, here's a test video I shot where the camera was within its capabilities.
Of course, all of this is hypothetical anyway, because if I was spending that much on a camera (the R6 costs about as much as all the cameras I have ever purchased put together BTW) I'd pretty much be asking Tarot Card readers for their opinion on it before listening to Jordan! 

DR is great but also really overrated. It's one of those things that really only matters to us video dorks. 

I'd say he was showing what can be done with the camera...
Logically, you wouldn't raise the shadows in that shot because there is no light source behind him, so his back should have been shadowed... even silhouetted.
And that's why it looks unnatural. 

low/no budget referred to the production value of the review itself, not to the type of productions it would be used on. As in - this review has been shot with a very low budget. They obviously don't use a big crew or have a gaffer with them, or even a proper DP. It's a run and gun review. With that knowledge, I don't expect too much. I just want to see simple demonstrations to illustrate what they're talking about.
Maybe your expectations are different, which is fine. Maybe if you post some examples of your work we can see what kind of level you're expecting? Not trying to provoke, only to understand where you're coming from.

Would love some more love for Canon 5d raw on this forum. Rather than topics about tech journalists. I used to enjoy Jordan and Chris. But my fascination for new cameras was the highest in the days of the gh2, gh3 and gh4, with some G6 magic inbetween. This cam tech youtube stuff is super videoish with dull images and astera lights of boredom most of the time. Kye discussed the phenomenon of microfilms and leisure time filming pleasures, personal vignettes with a personal and intimate approach. These tech channels do not inspire that. Jordan and Chris made many exiting videos for the camerastore but they were depending on the pioneering times of 5Ds, GH cameras and so on. Now its just a race for the lazy image with dynamic range overkill and pixel madness.

Now now, he's a camera reviewer who reviews cameras for making camera reviews, you have to keep a hold of your expectations!
These are the same people that keep making endless "how to get cinematic images" videos but for some unfathomable reason keep talking about new cameras and higher resolutions when the people who actually make cinema have basically been using the same cameras for a decade.

It's funny because when i was watching the video this morning I was thinking, "what a bad grade!" Sure, it is kind of a bland shot of a bland Alberta sunset but Jinkies, Scooby.

 Jordan: "if you need tons of flexibility in post, this lets you record RAW video internally--"
and the example of the flexible grading you're able to do with the internal RAW looks like he did the example grade in 5s, he raised the shadows in the underexposed clip and upped the saturation but that's it. Lazy if you ask me.

I am indeed! I meant to thank bloggers (including Andrew specifically) for bringing the issue of overheating up so much. The pressure about the timer nonsense forced Canon to change the way the camera monitors temperatures, which is the reason the mod works at all.

Everybody loves Mr Undone. The YouTube bros line up around the block to circle jerk with handsome Gerald, but I for the life of me cannot find any of the great guru's shoots!

Smug S1H owners titter in the background 😬
Canon R5 owners counter and bring up the subject of tracking AF 🤣
I like pretty much everything about the R5 and wouldn’t mind adding the fan…but then the power bank also…? 

Actually after watching the YouTube video all desire for this camera evaporated. Definitely an incredible deal but the reviewer in the video used a $43K lens, $4K+ stabilizer, generated 990GB of data, etc, etc and IMO after YouTube got done with it, the footage honestly did not look any better to me than C70, S1H, or A7S3 footage. The image stabilization wasn't even close to what even my S5 delivers without a gimbal let alone with a gimbal.
Cameras like these are like sports cars. No matter how good the deal is for the car, you need to be prepared to pay for all of the additional costs required to get the most out of it.
I have no doubt that the 12K source footage looked amazing, but for me, my final delivery platform is Vimeo, YouTube, and Instagram for most of my projects where all of that extra quality would be wasted.
