@bhwhitz Don't want to put more pressure on you but, what the hell, now that you've already put the idea out there, if you don't make that "GH2 Intra grading tutorial" cute little kittens will start to drop dead all over the place. Are you sure you can live with that burden? ;)

@bwhitz
Sounds great.

lenuisible

@bwhitz yes !!! please, please ...

kavadni

@bwhitz I think that's a great idea too

astraban

@bwhitz "I'm also thinking of doing a GH2 intra grading tutorial..." Please do this ! :')

Never, never buy a memory card on eBay. You're just asking to get a fake. For SanDisk, you really ought to buy from a SanDisk authorized reseller.

Any luck with Transcend 32 gb class 10 30MB and spanmybitchup? Great deals on ebay, 20$

Thanks! And amazing work on the patches! I was almost about to put some money together for a Scarlet, but I looked at my GH2 footage after shooting the beginning of a new project last night... and said screw it. I even pushed the CRAP out of it in post, didn't see any blocking or artifacts, and it retained it's fidelity/sharpness. Scarlet isn't going to make my stuff look much better than this. And it's going to weigh more and be slower.

Amazing work... :) I'll try to do some more technical testing soon. I'm also thinking of doing a GH2 intra grading tutorial... since I just found a way to get great skin-tones with some mid-tone adjustments.

@driftwood Just a heads up that I shot SpanMyBitchUp at 80% (30P) tonight for a wide cam and I am thrilled with the results. I used a cheapo card to see what it could handle, opting to rest the Sandisk Extremes and go with a Lexar Pro, locked in MF and used 800 ISO. Despite a theater shoot with predominantly dark areas galore, I can't find a single macroblock. IMO this is a major, major accomplishment and I'll be testing the Aqua v2 with spanning in similar circumstances soon. Very impressed. Great work as usual.

@bwhitz Welcome back :-)

Hey, been busy last month with a few things... ready to start testing again. Anyways, just loaded the SeAQuake patch and all I get is gray... with blips of blurry/glitch images... but mostly just a gray screen. Is there some playback method or something I've missed?

*never mind

I accidentally patched SeAQuake with PTools3.1

I'm dumb...

@driftwood,
is there a chance to get non-interlaced video 1080 50i in your patches ?

balazer

@wigginjs, just in case you didn't know, you'll get even higher quality 1080/30p shooting in variable 80% mode. You lose audio recording that way though. It spans in Aquamotion.

driftwood

@wigginjs I will defo take a good look at helping 1080i60 spanning. It could mean less bitrate & frame combinations though. Thanks for the report.

wigginjs

Just another data point: I tried SpanMyB****Up as well and it spans great for 1080p24, but 1080i60 doesn't span. I also am shooting in "P" exposure mode with auto-focus on. In case anyone is wondering why I care about 1080i60, if you run it through Handbrake and use the decomb filter it comes out looks really beautiful at 1080p29.97. It's a good way to shoot high-quality, high-action stuff in my experience.

Sandisk Extreme 32GB (non-pro)

driftwood

@wigginjs Interesting result. I havent had a lot of time to test AQuamotion v2 FSH with spanning. The initial test of mine worked well. I'll look into it for ver 3. What SD card was it out of interest? 1080p24 is safe, that I know.

wigginjs

FYI. Just shot a bunch using Aquamotion V2 1080i60 (FSH) and got a lot of write speed errors after various lengths of time. I had one clip make it to 9:07, but then stopped when the file size reach 4GB. Is this unusual? Does the patch only span at 1080p24?

@driftwood
The result above was with ISO12800.
Although I am testing again with ISO800 now, continuation recording can already be carried out over 20 minutes.
With ISO3200, but, it did not span.
I am not testing about other ISO.

"streameye"
Although there is no telling whether I can use, I try also on ...!

driftwood

@bkmcwd That new graph looks better to me. Also use streameye to check your macroblocking :-)

bkmcwd

@driftwood
Instantly, now, when I tried, recording stopped at 4:59 as expected. :-(

BTW,Although I used Elecard for the first time, I think that this is very interesting.
Since what was not visible until now can be seen, selection of the parameter currently afflicted becomes easy now. :-)

@driftwood
Thanks for your reply!

"you could bring 176M down to something"
"Yes!"
After being pointed out by you, I tested a lot of times in a hurry, and I adjusted to 143M.
Of course, I readjusted frame buffers and Top and Bottoms.
Although it is still in the middle of creation, probably I think that it becomes the patch without waste of bitrate.
But on the other hand, I think from the result of high stress tests, and when I walk shooting upper in a forest(like my vimeo /32247121), I am imagining that the maximum frame size will be compressed. :-(
From yesterday, since the weather is bad, I cannot try in the forest yet.
I think that the 143M patch may be sufficient as long as it is satisfactory, even if I walk actually shooting upper in the forest.

"Actually have you checked to see if your latest patch spanned?"
Since I thought that it naturally did not span, I have not tested yet.

driftwood

@bkmcwd There is nothing wrong with the patch you did but its just that drop in the graph and its collective use of bitrate which suggests you could bring 176M down to something much lower for the H setting and still get the same results. Actually have you checked to see if your latest patch spanned?

bkmcwd

@driftwood
Thank you always.

I thought if there is possibly a misapprehension between you and me when I try many things after that.
I think that the advice to me from you is "using the special high bit rate effectively."
However, as for what I aim at with this Q18 patch, "usually, it is the low bit rate as much as possible, and frame size becomes large in case of under high stress."
Although I think that the result of 66-88M probably comes out of this patch in the common range, if the high stress in the case of carrying out the action shot in a forest like me is expected, with 88M, the frame size of civil time will become very small in 3GOP.

From the above reason, I have set this as 176M.
I also think that the bit rate may be useless as surely you say, but this is just the result of my aiming.
Since you have solved the frame size under the lowlight which was before scrupulous, I am making the more practical variation now. ;-)

Supposing that I doubt has the frame size as a result, and an ideal chart of Streamparser, it is satisfactory even if the buffer is not the maximum then?
Possibly ... what ... it is ... although there may be a problem, I think that I am satisfactory here unlike the problem of the maximum video bit rate pointed out from Stray or Chris.
Supposing it only simply "is wasteful", this Q18 is satisfactory.

However, supposing there is a defect fatal in addition to it, what is it?
Although I think that such a problem cannot be found by me, how am I?

Thanks for your exact advice!
Although my real intention gets across to you in my strange English or I am worried ... :-(

P.S:
About the encoder setting which you pointed out, IMHO, I consider that what I changed from your original slightly by myself is better.

@Huckster
VK has mentioned that he is still fixing the search engine in P-V, so while he is doing that, simply use Google 'in site' search, type this into Google:

foobar site:personal-view.com

(replace foobar with your search word- you can also search for images this way as well)

Considering that the 45MB/s are suddenly working 32gig + (8-16 never worked) and the 30MB/s 32gig work- now 64gig 95MB/s have been reported to SPAN INTRA 170! (huge news) I should go through the old posts and try to make up a spread sheet of peoples finding...

Howdy, Stranger!
