[The common feature of my settings]

For example, if some setting tries to use low qp with the frame size limited like Intra, many level lines of the high qp macroblocks will also appear in each frame pictures. Although it is unclear for appearance in looking with eyes, it means that the codec is not committing this correctly. I am making the settings which can use the lowest possible qp appropriately, avoiding this isuue by using the biggest possible I-frames. On the high detailed scene, if the minimum qp is too low, the range of qp will spread and, as a result, many of these level lines of the high qp macroblocks will appear.

Therefore, in my settings, on the high detailed scene, it has adjusted so that the minimum qp may become high appropriately. On the other hand, it has adjusted so that the lowest possible qp can be positively used under the lowlight. I think that 3GOP can realize this all-round performance with the motion. Therefore, when using my settings as only for lowlight, you may feel thing insufficient only a few, although sufficient dark place performance is still given. However, also in a bright scene, the codec hardly wavers with my settings. This is the point that especially I am scrupulous.

And

My top priority is "recording does not stop by any means in any situations."

*The issue which the high bitrate hacked GH2 cannot often span more over 4GB is not contained in this.

In order to adjust so that recording may not stop in a high stress scene, you have to test supposing the stress beyond it. I have spent many hours also on the torture test for it.

*The purpose tested with this screen is the check of durability or reliability to the last. About image quality, it cannot check at all by this test.

I understand that this test exceeds the stress assumed practically. However, in the settings which cannot clear this test, the Risk of Freezing Camera momentarily practically is large.

Moreover, although the issue of "freezing the moment a focus suits" is recognized in many other GH2 settings, about it, it cannot necessarily solve only by this test. I have also solved this issue now by the test which repeats focusing for several minutes.

I aim at the setting not freezing.

If my settings may become unstable with SanDisk 95MB/s SDXC, please give me feedback.

*The spanning is possible perfectly in 24p with SanDisk 95MB/s SDXC.

These features are common in almost all my settings.

REMEMBER: IF YOU USE THESE SETTINGS PLEASE MAKE A DONATION ABOVE TO VITALIY KISELEV FOR HIS TIRELESS WORK IN MAKING THIS HAPPEN. THESE SETTINGS ARE TOTALLY DEDICATED TO HIM. THERE ARE MANY QUIET USERS OUT THERE WHO HAVE NEVER BOTHERED OFFERING ANYTHING. PLEASE, PLEASE HELP TO KEEP THESE HACKS GOING. NO MORE DONATIONS = NO MORE SETTINGS. IF YOU HAVE MADE A SMALL CONTRIBUTION IN THE PAST, NOW IS THE TIME TO DONATE AGAIN. Thank you, bkmcwd

Again, special thanks to @driftwood, @cbrandin, and of course @Vitaliy_Kiselev! :-)

AN "Valkyrie", GOLGOP3-13, GOP3ZILLA, natural, Freeze-less Reliable All-round GOP3 Settings :-) http://personal-view.com/talks/discussion/2960/an-valkyrie-golgop3-13-gop3zilla-natural-freeze-less-reliable-all-round-gop3-settings- Sat, 21 Apr 2012 02:30:56 +0000 bkmcwd 2960@/talks/discussions Series 2: http://www.personal-view.com/talks/discussion/5385/gh2-freeze-less-reliable-all-round-settings-series-2-valkyrie-golgop3-13-gop3zilla-natural-


The meanings of my account name "bkmcwd" are "Burger King, McDonald's, and Wendy's." LOL Please do not mistake! :-)

At the same time as the silent users of my settings have increased in number, the request to me has also increased. Moreover, those who improve my settings uniquely also appeared. Therefore, I start a new topic, in order to arrange them.

I am a resident of Official Low GOP Topics. I was shocked from @kae's 3GOP in August, last year. In compromise to image quality and motion, I have thought since then that 3GOP is the best solution, in some mode like 24p at least. Although surely many wonderful longGOP settings also exist, the clearness of noise grain does not match Intra and 3GOP.

It is serious that I acquire information from this forum since I am poor at English. And in Japan which is a home country of GH2, I was hardly able to acquire information. However, I have learned much know-how from many experts, @cbrandin, @LPowell, @Ralph_B, @balazer, @towi, @Stray, @proaudio4..., especially the great settings of @driftwood!

I do not know whether my settings are the best. However, since those who are pleased with my settings adhering to big I frame size and short GOP have also increased in number, I continue improvement further more.

Because my English is poor, there may be many unclear things, but I do my best in some questions to answer enduringly.

These features are common in almost all my settings.

[The feature according to type]

About "Valkyrie", it is to here:http://www.personal-view.com/talks/discussion/4391/apocalypse-now-quest-for-simulated-444-smooth-cinema-quality-driftwood-cbrandin-bkmcwd/p1

Since the link place was closed, Valkyrie of the new improved versions have been released in this thread. Please look at the latest information on downward.

"GOLGOP3-13" series is the settings for using low qp under lowlight positively. Simultaneously, it has tuned up so that a codec may work also in the high stress scenes as correctly as possible. The value of "Q13" to which I have stuck from last year realizes high image quality by practically lowest qp.

Furthermore, the original matrix is adopted in the newest GOLGOP3-13s. It is the middle of a Sedna matrix and a stock character. If it says plainly, it will be the Sedna matrix optimized in 3GOP structure.

"GOP3ZILLA" series is the all-round settings which covers all the scenes with the mean bit rate. In a general shooting, this series realizes the highest image quality with the value of "Q15" to which I have stuck from last year.

This is the simple setting which harnessed the feature of the stock as it was. I recognize this to be the normal evolution version of the stock.

"natural" series is the economical settings which covers all the scenes with the mean bit rate. In these series, it has also aimed that a codec works correctly also in a however high-stress scene. The value of "Q18" to which I have stuck from last year realizes the safest and good balance setting.

"MAX" versions in each types are the settings using maximum I-frame size which GH2 can use in24p mode. However, with MAX version, playback in camera may not often be available in 24p. This is because the maximum frame size which can be played back by GH2 may be exceeded. Of course, the file which cannot be played back in camera can also be satisfactorily played in PC. Supposing you consider that the playback in a camera is important, I will not recommend you this setting. Please use normal version. However, IQ of MAX version is better than normal versions, IMO.

"A" means "Almighty" or "All-around". Since former GOLGOP3-13s were not able to use the too much low base Q all around, "standard" and "lowlight" were prepared, but since latest GOLGOP3-13 controlled qp appropriately on all the scenes, it was taken as "A." Unlike "MAX", in this "A" edition, in-camera-playback can be available in all the modes also including 24p.

*I decided that I did not use the name of "standard" and "lowlight" in the newest settings.

"standard": The Almighty setting which the codec works correctly as much as possible on bright scenes, and realizes low qp under the lowlight.

"lowlight": Although the codec may waver in a satisfactory grade on bright scenes, realize strongest high image quality under the lowlight.

*These features are mainly in 24p.
