@MinorHD Really nice!

Just been running a few tests of Sedna A Q20.

Aiming for high detail deep DOF shots with a Tokina 11-16 and an ND filter Aperture closed down to around f11 mostly. In camera I stuck to 200 400 or 800 iso and 1/50 shutter, I only shot at the highest bitrate 24H option in cinema 24. NR was -2 everything else -1 and 'Film Mode' was Nostalgic, exposure manual.

When I reviewed some of my shots they had a band down the right side of the shot that is about 1/10th of a stop darker than the rest of the shot. This didn't happen in all shots though.

I was able to fix it in post without too much trouble but wondered if there was something I was missing that could be causing it?

Here is an example, the first shot and last shot have the band of lower exposure (there are only 3 shots in the video).

And here is a graded version which corrects it -

Thanks in advance!

@Bueller Would be great to include it in the follow-up testing. :)

@thepalalias Thanks I will do this over the weekend then post.

@bmcent1 Yeah I think v1.1 maybe fixed it cause I never seem to have to do that with my camera.

@exilenorth I will definitely let you know next time we test.

The PTool 3.64D patches should still work with PTool 3.65D but my suggestion is to create two versions of .BIN file (one with PTool 3.64D and one with the newest 3.65D with FW 1.1) and do a controlled shot with one right after the other.

If the artifacts only show up in one vs. the other, we should be able to identify them in screen grabs and possibly debug the issue. If the two turn out to be similar, then it may be that the shooting conditions were the issue rather than the setting.

@bmcent1,

Nick (Driftwood) is always primarily concerned with improving quality. Second to that is satisfying the needs of, for example, documentary shooters who want spanning. Sedna followed Quantum so Sedna is an attempt to 'better' quantum and its various matrices. He provides these 'updates' free of charge and for the benefit of the community. There's no go to update that will satisfy the needs of everyone. It's a £600 camera that is being pushed a lot further than its maker intended.

Unfortunately you have to read a lot and ask questions, but never demand. My understanding from reading these forums is that HBR will never be as good as 24p because of the interlaced wrapper business. And I don't think the gh2 will ever be a 'great' low light performer, but it's still good. I've shot at 1600 ISO and used a denoising filter...the results are acceptable. The best thing to do though is light your scene and stay within ISO 160 - 800 (don't forget the ISO bug though!)

I'm using Sedna A Q20 and have found that there is more latitude when grading when compared to earlier releases. I'm only interested in shooting 24H(p). In Nick's opinion (I think?) Mysteron and Mysteron Burst are theoretically better than Sedna (but they are experimental and some are saying they don't grade as well). Canis will be the best for 24H(p) when Nick releases it, but for other modes...who knows? There are too many variables to have a one update fits all solution if maximum quality is your prime goal. Horses for courses I'm afraid, but Nick always provides enough information about his updates so that you can make informed decisions.

Best of luck

Thank you @thepalalias!

On the your second bullet point, you said Sedna twice, what has more detail than Sedna or Sedna has more detail than what?

Is it safe to assume that the newer settings, provided they don't give you write errors, have higher quality than older settings?

@DavidHjlindberg Are you adjusting the white balance to compensate?

@Siddho, thank you

Thanks for the reply @thepalalias. I saw your table. I'm not that interested in spanning, personally. But I have to think when @driftwood or @LPowell set out to make new settings, they must have some goal in mind. Looking through the threads I haven't figured out what it is but a table or quick summary could be a good starting point to understand if it's a setting I should try or not. For example, has someone optimized for HBR (30p), or has someone optimized for low light or higher motion scenes, etc? There are a lot of variations even within Driftwood Quantum X series, so I wondered if it's spelled out somewhere what the "subspecies" ;) are intended to do.

@jrd It's a playback only issue, at least if you are encountering what the rest of us have from time to time.

@bmcent1 It's not quite that simple. If you want tables, here is one I started for the spanning data on the different settings. http://perlichtman.com/pasdenapulse/wordpress/gh2-hack-reference/

As you can see, if you are using a SanDisk 64GB 95MB/s, you can get spanning with either Sedna or Mysteron inn 24H mode, but if you want to span in SH mode, you are much safer using Mysteron than one of the Sedna AQ1 A modes. In theory, SpanMyBU V2 should span on a wider range of cards but I have not tested Orion in this respect using the setup for the table.

Other than that, Pictoris takes up less space than the above settings and Cluster takes up even less space than that (thought Cluster is not an intra setting like the others).

@Siddho, Hi I am interested in trying the settings you mention, where can I find GOLGOP3 to combine with Sedna? Or is it possible for you to post here a zip with the settings combined for those of us that do not feel at ease with combining settings in Ptools? Thank you in advance
