@cosimo_bullo
Thank you always! I respond to your request. :-)

Of course, I have also already tried his patch before travel.
I liked the extreme setting as you knew, but his set was too going too far to completely use FOR ME truly.
Many frames have fallen at the time of the practical highest stress which I assume.
Although I am thinking the character under lowlight as important, I think that balance is important.
If used only under limited conditions, I will also think that his patch is very attractive.

After 3days travel, I came back to the house. :-)

@Stray
Probably I also regard my 154M set as the ability of neither ETC nor the 80% mode to be tested under high stress.
However, it is although I do not think that I would like to raise QP in order to be able to use these... ;-)

@Ralph_B
Thank you very much for your wonderful test!
I am satisfied with the result of your test.
Although, as for the set of Q10, frame size should become larger, did you test it?

@sohus
Thank you for testing my patch!
What is QP or AQ in your new 154M GOP3 patch which survives your test?
By the test of my past, if it is Q14 or more than Q16, also not AQ3 nor AQ4, it turns out that the form of cadence at the time of super-high stress does not become a flat line easily, but since I am thinking as important the practical use level, especially lowlight, I am using Q12 and Q10 or AQ3.
I do not feel a problem at all on these practical use.
Although it becomes behavior also with AQ3 same flat cadence under super extream stress, since frame size becomes small from Q10 AQ3 at the time of lowlight, I like Q10 version.

Most tests were not created for the Sandisk but on the Sandisk.

Also, I see future cameras leveraging the UHS-1 cards so I don't think it is a very wise investment to buy heavily into the Extreme Pro cards now. Most patches run fine on the Transcend, only @bkmcwd and @henryolonga's new patch have serious problems on the Transcend card, but they are extreme settings.

I am sure @Stray's 88M was never created with SanDisk Extreme in mind. I will retest the two patches mentioned above once I get my card, all other patches run fine on the Transcend so no need to retest.

@stray I took your dense chart, imported it in After Effects, and put a 'Wigglerama' filter on it that zooms, scales, rotates in variable speeds and intervals. I was not sure if it would work but so far I have crashed many patches that survived my regular Death Chart test just fine. I loop it and do 2min - 4min tests. So far, it has resulted in memory card speed errors for many patches. I am pretty confident that it does work as I hoped for that reason. I have an iMac 27" high res screen. I test them using the 14-140mm lens at 25mm, F/5.6 and ISO800 (and 1600).

I think this test is as extreme as it can get. But because it is indoors, lit by my monitor and an AE project, it is very easy to test every new patch this way and compare results.

@Driftwood's GOP1 patches survive it just fine, his GOP3 132M fails (also on static Deathchart)
@Cbrandin's GOP12 patches survive it just fine (MAX VAR as well)
@Sohus' new 154M GOP3 patch (based on foundation of H. Olonga's patch) survives it just fine
@bkmcwd has to wait, as my Transcend doesn't like it, so I ordered a 8GB SanDisk Extreme for test purposes, arriving tuesday. I also hope to improve upon my modification of Olonga's patch to get it stable with that card.

@sohus

The notes say: bkmcwd 154&154MB 3GOP Q=12 FBx3 FLx1 TBx8.6 VB3.6
When I downloaded it, I put the date Oct 9, 2011 on it. Hope that helps.

@sohus Yep, I'm onto it, and the ETC/80% problems. I'm pretty sure I can fix both and tighten it all up, but it will take about a week or so with my other commitments at the moment.

@Stray 88M can become unstable (in controlled testing). I have made a motion deathchart in After Effects and I get occasional drop-outs with Stray's 88M patch. It only happens once in a while but it indicates a buffer overrun. I see it in other patches too, where you get one or 2 frames that are like 10k in size.

More HDMI Testing - BATTLE OF THE TITANS

It's come time to test the high end contenders against the absolute reference - lossless HDMI output. This was a punishing nighttime test at ISO 6400. HDMI capture was done simultaneously with in-camera recording. The lineup:

Driftwood's 176M GOP1
bkmcwd's 154M GOP3
Stray's 88M GOP12

These are Photoshop TIFs with layers. HDMI is on the bottom, AVCHD on top. Toggle the top layer on and off and compare the two.

IMPRESSIONS:

It's a tie between bkmcwd's 154M GOP3 and Driftwood's 176M GOP1. Both are perfection. I don't believe you can get any closer to the the HDMI than these two patches. Stray's 88M comes close, very close. And at half the data rate, it's a viable option for high end recording.

EDIT:

I have since run these clips through stream parser.

@PixCanFly I really cannot recreate the problem with ETC mode that you get, and with the same card too. The image quality of the 176M isn't actually that different. If you look at stills in post of the same scene and push the image a lot, the size of the blocks are actually the same as the 66M AQ2 GOP12 settings. The I-frames themselves are quite a bit smaller with the 176M. However, the motion of GOP1 is breathakingly good, but when it comes to post work it's actually no better. http://personal-view.com/talks/discussion/comment/18767#Comment_18767 the motion does make it look amazing, but it doesn't actually mean the image quality is better in terms that relate to post work (grading, compositing, colour correction etc).

But if you are doing a lot of heavy post work, and you aren't transcoding your footage first to another intra format then the GOP1 will be better everytime as it won't suffer the generational loss as badly as a long GOP stream. If you love the look of the 176M GOP1 though I'd say stick with it, you'll only be constantly hankering after it's look now you've experienced it shooting everytime that you use other settings. ;) Actually the codec is doing more work arguably with a longer GOP than GOP1 really (creating spatially based I-Frames alone is probably a lot easier than creating B and P temporally based frames), maybe thats the problem/difference with the 88M settings.

Thanks stray. I'm going to keep your 88m loaded on my camera despite the occasional card speed error. It seems to be the best compromise between motion quality, image quality, and file size.

@Stray
I get the same result like @bdegazio.
I am using Sandisk Extreme Pro 32GB UHS.
24H - ETC on, works OK; 80% mode fails with card speed error about 50% probability.

@Stray
Just to be sure that it's not an issue with my Sandisk Extreme Pro 45MB/s, I'll borrow a 'approved' Sandisk 30MB/s extreme to test your 88M again.
