  • @mclarenf1 Buy 6 more 32GB cards..?.....jk

    @driftwood --- but seriously how much SHOULD you be able to get on a 32gb?
  • Format the card?!
  • I ran reAQuainted on Transcend 32GB class 10 card. Blowing tree leaves looked amazing while not throwing away dark background detail. Amazing. But, alas, I am only getting 6 minutes on the card. Any ideas?
  • I'm totally agree with Driftwood. For me reAQuainted is the best GOP1 patch. I only need 1050 i/720 25 P stable settings in the same patch . It will possible?
    Thanks
  • @driftwood

    I quickly tried your latest intra patch 'reAQuainted'. It looks great.

    Thanks and keep your great studies!

  • Sorry, also @driftwood. The 100 mb GOP1 settings you posted a while back. Two questions: 1) did you have any problems with them and 2) if I wanted to apply your better Q quality from the lastest GOP1 patch, what would I alter? Sorry man, I know you must get bombarded with questions, but I'm really curious about the 100 mb GOP1 -- I'm getting excellent, excellent run time and quality from it and it feels to me the perfect thing to load into 24L for doc interviews, while keeping 24H free for B-roll & beauties with the latest and greatest of your ever evolving 176 gop1, or at least keep one loaded on one SD card and another on another SD card.

    PS: It also spans!
    PPS: And it runs fine on Transcend, ADATA and Lexar so maybe those won't be relegated to gopro afterall...

    EDIT: Tried bumping up AQ to 3 -- stopped spanning. So ignore most of the questions. But driftwood, if you did find any bugs with the 100 mb GOP1 let me know -- I assume you didn't as you're known for your rigorous testing, but I wanted to ask just in case.
  • @JDN You can get away with 135M but it will buffer underrun on a death chart. 145M is a safe bet, so not much on the saving sorry :-( This is the only way to keep the i frames and buffer top notch.

    Also, everyone, I very much doubt we will be able to take this any further in terms of size of i frames. I believe 'reAQuainted' could be the best GOP1 INTRA patch now but I would like some of the other chaps to test it against QuantMeBaby, the 244M patch, etc.. etc...

    My own tests confirrm 'reAQuainted' is making best use of quality macroblock QP. But I'll be happy to be prroved wrong. :-)

    I just wanna thank Vitaliy, cbrandin, Kae and ALL you other guys for inspiring me to achieve the very best INTRA settting we can get.
  • @Driftwood -- just tested the new patch. No problems, looks great. Chews up card space like a mofo, but that's the price of quality.

    On that note, what is the lowest bit-rate GOP 1 that you've got stable? I was wondering about setting it as 24L to give a longer-run option for doc work -- I don't mind starting a new clip every 10 - 12 minutes in an interview, but every 4 minutes is a little much :-)
  • I have another Video Made with Driftwood's 176 v3 - I'm not as good as the others and is is sometimes a little bit shacky and focus loss during zoom. But i like it! All Hand Hold...

  • @Driftwood, what do you reckon will be the max size for P/B frames in a GOP3 patch with maximized iFrames (1,180). About 500 - 700? Is there a way to set a minimum size for those? I know you have two great GOP3 patches at around 800k constant but I would love to have a GOP3 (1180/X00/X00) patch. Where x stands for the maximum size of the P/B frames (and would love to have it constant).

    Something else:
    I have a 176M/154M GOP3 setting that survives my motion deathchart for 1500+ frames with great P/B frame sizes. Then I get a 2 frame drop-out, after which the streamparser graph drops 2 frames every 100 - 200 frames. What does this mean? Maximum reached? Or do I need to adjust FB1, FB2 or FL? I have a gut feeling that at a certain point a buffer overflows and the whole stream starts to stutter because of panic :)

    Can you tell me what FB1 and FB2 do (why 1, 2) and do they relate to each other and/or the FL? I am trying to understand some important parameters and their relation so I can figure out a way to fix things. Also: what does the Muxer buffer do? Is it related to writing to the card or constructing the TS stream?
  • Well, its more in control of Q now. :-) Try it against the others -have fun.
  • @driftwood - Higher or lower average rate than the last 176? Will test shortly.
  • People want min QP of 4 and max QP in the 20s for great quality? Then try this AQ3 'reAQuainted' variation of the killer INTRA patch.

    Very Nice! I like it!
  • Let's hear about it Perry!

  • WOO IM EXCITED FOR SO MANY THINGS RIGHT NOW!!!
  • Driftwood's GH2 cam1 is out of action after finally sending it in to fix the two dead pixels in the EVF. So GH2 cam2 is out with some improvements to GOP1 coming soon.
  • @Rambo

    Thanks - appreciate it.
  • Captivating Hallvalla....
