I second this, I'd love to see the same scene recorded by both the Ninja and internal AVCHD. I want to see in person the difference 4:2:2 can make when it comes to colouring a shot.
You can download some ProRes footage here https://vimeo.com/54530924 It's from a Hyperdeck Shuttle so you will have to remove the pulldown yourself, so far it has been the only externally recorded footage from the C100 that I can find.

Sorry I do not have an actual clip to post but I do want to weigh in on something. On the surface, some footage shot to both the SD cards and the Ninja will appear noisier on the Ninja. It is a very, very fine grain that infiltrates into certain darker areas that is not apparent in the AVCHD footage. At first it appears to be a bad thing but when you scrutinize it, you see there is actually more detail in the area too. So the overall image seems sharper or more crisp. In comparison the AVCHD footage might appear cleaner but upon inspection the footage also appears a bit muddy in these areas as the compression is averaging pixels, which effectively reduces some noise at the expense of image detail.
Unfortunately I have been editing strictly with Prores since I got the camera in May, and prior to that I had the Samurai with my XLh1 and I edited strictly ProRes too. If I have the opportunity I will try to get some comparison shots. Honestly I don't see much of a difference most of the time though. The AVCHD is pretty robust.

Thanks for that interesting info. I have always shot compressed AVCHD and had heard about 4.4.4, 4.2.2, etc and never really bothered to find out about it. Then I decided to investigate what all the fuss over the C100 paired with the Atomos was all about and did my research. Second step was to download a Prores HQ clip (not from a C100) and mess about it with on my CS6 timeline. Didn't look any better than my c100 footage UNTIL I started to grade it and generally abuse it with colorista and WOW! Then I saw what all the fuss is about. You can do so much more grading with it and keep it looking fresh. Weddings will still be with AVCHD but music vid, promos, short films etc Prores is the way I'm going.

The AVCHD is fairly robust, but you still cannot edit effectively in AVCHD except for very short simple pieces. You still must transcode (whether in the background or not) to have an edit codec that you can work with efficiently. The Prores or DNXHD files save time with certain NLE's and make the edit smoother in the long run. ProRes HQ has more information and therefore more detail and that can show in the C100 as more noise. The place where the AVCHD falls apart is in the Chroma information. If you edit in AVCHD you will have problems with chroma noise and artifacts. Some of this can be dealt with in the transcode but varies depending on the footage. While there is no silver bullet (speed and quality) for C100 material, the use of the Ninja or possibly a Odyssey 7 series recorder recording Prores or DNXHD files gives the editor a fighting chance.
I now recall having to so some color correction on some AVCHD footage from the C100 of a Dance Recital. Upon doing normal corrections I did see a lot of blockiness in the dark areas that I have never seen when editing ProRes. It was harder to correct flaws in the footage without seeing obvious degradation. As I said however, I primarily use ProRes so I don't have many good comparisons.
Interesting....I downloaded the prores footage from the link that jaredcgray posted earlier in this thread. It wasn't from an Atomos (it was from a Hyperdeck Shuttle) but is from the C100. Once I started playing with levels, I immediately noticed what seemed to be noise in the trees, I wasn't pushing it that far but the noise jumped out at me. I'm sure there wouldn't have been that much with the straight AVCHD footage.

I shot the C100 and Ninja in ProRes for the Canon CN-E primes review and haven't had the time to go back and compare them. I didnt shoot in HQ but I think HQ is overkill for the C100 8bit out. I will try to compare and report back but I cant do this until next week. I'm curious to see but I already have seen the improvement in test done by others. I've had a few issues with the Ninja and need to contact Atomos about them. The issues is micro blocking and the recorder not recording in 24 frames after the Ninja 2 3:2 pulldown setup was completed.
probably because the prores is 220mb a sec ! and that footage is just 400 mb but its like 12 sec long !
we need some genuine prores 422 footage without compression, but its just not ideal to share on the net since its too big to download ~!
I really want to see it as well cuz im on the edge of buying a atomos blade for 422

I can understand wanting to compare the Ninja ProRes with the camera C100 AVCHD as i was also inquisitive before purchasing my Ninja 2. I decided to go for it and have found there are many other pros the Ninja/Samurai offer - second screen, no transcoding in post, true progressive in 25p, longer recordings, and in the case of the new Samurai Blade a high res screen for focus. (I'm not convinced by the C100 LCD or the Ninja 2 screen for focusing :-/ )
On the couple of occasions I used Acvhd I've realise I don't want to use it again unless i have to because it needs transcoding, especially when projects get big. The internet comparison tests I've seen have concluded that the ProRes is better for keying and green screen work and that Canon have done a good job with the internal codec. I have shot some 2 camera projects with the Red Scarlet and the C100 Ninja 2 combo and the editor / colourist was impressed with the ProRes footage from the ninja 2. In fact he found it harder to get the look he needed from the Scarlet - perhaps there can be too much colour information?

Audio Sync problems are a concern though on the Samuri Blade from a few reviews I read.

Ran across this video today showing both codecs. The ProRes is sharper showing more detail.

Eric,
Did you ever get your issues with the Ninja 2 worked out?
Was it a known problem with the Ninja 2 and current firmware or an operation issue?
I can't really count on the Ninja 2 if there are these constant problems. Mine comes in today.

Drew, have you raised the contrast on the LCD screen to help with focusing. I believe I have mine set at +50 on contrast and +4 on sharpness on the LCD setup menu. This does help with focusing, but your right, the screen is not ideal.

I haven't had time to mess with it but I'm concerned because I've only used it a few times and had two failures. Always double roll with the internal codec on SD cards this is the best practice anyway.
The one shoot that it worked flawless was for the Canon CN-E review I did. I was all over Balboa Park for several hours shooting. Powering on and off and setting up the pulldown several times with no issues. Then I shot some fireworks and the recorder was set to 24p but recorded in 29.97. Weird since it shouldn't be able to even record.

I see a color shift that doesn't make sense in the comparison. I don't think he was recording on the internal SD card at the same time. Makes judging the test a little gray.

From the Vimeo description:
So he had 2 cameras (side by side?), but also 2 SD cards and 2 Ninjas???
